Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments.

With the development of electronic technology, electronic devices (such as smartphones, tablet computers, etc.) have become more popular and have more powerful communication functions in people's daily lives. For example, the electronic device needs to have a near field communication function, a navigation function, and a far field communication function. Since different communication functions correspond to different communication frequency bands, the communication frequency band can be subdivided into a plurality of communication frequency bands even under the same communication function.

For example, the communication band of the near field communication function may include a bluetooth communication band, a WIFI band, and an NFC communication band. The WIFI frequency band may include, for example, at least one of WIFI2.4G frequency band, WIFI5G frequency band, and WIFI7 frequency band. The communication bands of the navigation function may include a GPS-L1 band and a GPS-L5 band. Far field communication bands include Low Band (LB), medium high band (MIDDLE HIGH band), and Ultra High Band (UHB). Specifically, the far-field communication frequency band may include various frequency bands of the NR frequency band and the LTE frequency band and a combined frequency band to satisfy wireless communication of the electronic device under 2G, 3G, 4G, 5G, and even 6G broadband. Currently, the wireless communication frequency band under the common 5G broadband is a UHB frequency band, and the UHB frequency band can specifically include an N77 frequency band, an N78 frequency band, an N79 frequency band and the like.

In view of the requirement of operating in multiple frequency bands in an electronic device, a common way is to provide multiple antennas corresponding to the multiple frequency bands in the electronic device. However, providing a plurality of antennas may require a large space, which is disadvantageous in terms of miniaturization and portability of the electronic device. Therefore, a technology of arranging a plurality of antennas for realizing a plurality of wireless communication functions in a small space is demanded.

It is proposed in the related art that the functions of a plurality of antennas can be implemented using antenna assemblies in a common form. The radiator of the common antenna can realize the common body of a plurality of different antenna modes, different antenna modes can meet different communication functions, and the common body form also reduces the occupation space of the antenna component.

However, how to enable the antenna assembly in the form of a common body to cover the frequency band for navigation communication, the frequency band for near field communication, and the frequency band for far field communication at the same time and occupy a small space is a technical problem to be solved.

As a possible way, as shown in fig. 1, the antenna assembly 10 may be arranged to comprise a first antenna element 11 and a second antenna element 12. The first antenna element 11 comprises a first radiator 111 and a first feed 112. The second antenna element 12 comprises a second radiator 121, a second feed 122 and a third feed 123. A slot 13 is formed between the first radiator 111 and the second radiator 121, and the first radiator 111 and the second radiator 121 are coupled through the slot 13, so as to realize that the first antenna unit 11 and the second antenna unit 12 are a common-caliber common-body antenna. In other words, the first radiator 111 and the second radiator 121 belong to the same radiator, and the one radiator has a slit 13 to divide the one radiator into the first radiator 111 and the second radiator 121. The first antenna element 11 or the second antenna element 12 formed as a common body antenna may use not only the radiator itself but also the radiator on the opposite side when operating. Meanwhile, the antenna assembly 10 can realize multi-band signal transmission in cooperation with different radio frequency signals (also called feed current or exciting current) received or transmitted by the first feed 112, the second feed 122 and the third feed 123.

It should be noted that the coupling in the embodiment of the present application is "capacitive coupling". By "capacitive coupling" is meant that an electric field is generated between two radiators, the signal of one radiator can be transferred to the other radiator by the electric field, and correspondingly, the signal of the other radiator can be transferred to one radiator by the electric field, so that the two radiators can realize the conduction of an electric signal even under the condition that the two radiators are not in direct contact or are not directly connected. For example, the coupling of the second radiator 121 with the first radiator 111 through the slit 13 means that the second radiator 121 generates an electric field with the first radiator 111, and a signal of the second radiator 121 can be transmitted to the first radiator 111 through the electric field, so that the second radiator 121 and the first radiator 111 can be conducted by an electric signal even without direct contact or direct connection. Accordingly, the first radiator 111 may generate an electric field with the second radiator 121, and a signal of the first radiator 111 may be transmitted to the second radiator 121 through the electric field, so that the first radiator 111 and the second radiator 121 may be electrically connected even without direct contact or direct connection.

As shown in fig. 2, the antenna assembly 10 may be employed within an electronic device 20. The electronic device 20 may include a top wall 21 and side walls 22 on either side of the top wall. As shown in fig. 2, the sidewalls are a first sidewall 221 on the left side and a second sidewall 222 on the right side. Wherein the first sidewall 221 and the second sidewall 222 are areas for gripping.

The first ground D is located at an end of the first radiator 111 away from the second radiator 121 and is used for grounding GND1. The first free end C is located at an end of the first radiator 111 near the second radiator 121. The first feed point E is located between the first ground terminal D and the first free terminal C, and the first feed 112 is connected to the first feed point E.

The first feed 112 corresponds to an antenna ANT1, the antenna ANT1 having a resonant mode corresponding to a first target frequency band.

Optionally, a first matching circuit M1 may be further disposed between the first feed source 112 and the first feed point E, where the first matching circuit M1 is configured to perform impedance matching on an excitation signal sent by the first feed source 112, so as to excite the first radiator 111 and/or the second radiator to resonate in the first target frequency band, so that an antenna ANT1 corresponding to the first feed source 112 has a preset S parameter. Meanwhile, the first matching circuit M1 is further configured to filter the radio frequency signal received or transmitted by the first feed source 112.

With continued reference to fig. 1, the second radiator 121 has a second ground terminal H, a second free terminal I, a second feeding point F, and a third feeding point G. The second ground H is located at an end of the second radiator 121 remote from the first radiator 111 and is connected to the ground GND 2. The second free end I is located at an end of the second radiator 121 near the first radiator 111 with the gap 13 between the second free end I and the first free end C. The second feeding point F and the third feeding point G are located between the second ground terminal H and the second free terminal I.

The second feed source 122 is connected to the second feed point F, and the radio frequency signal received or transmitted by the second feed source 122 may excite the first radiator 111 and/or the second radiator 121 to resonate in the second target frequency band. The second feed 122 corresponds to the antenna ANT2, and the antenna ANT2 has a resonant mode corresponding to the second target frequency band.

Optionally, a second matching circuit M2 may be further disposed between the second feed source 122 and the second feed point F, where the second matching circuit M2 is configured to perform impedance matching on an excitation signal sent by the second feed source 122, so as to excite the first radiator 111 and/or the second radiator to resonate in the second target frequency band, so that an antenna ANT2 corresponding to the second feed source 122 has a preset S parameter.

The radio frequency signals received or transmitted by the first feed 112 may excite the first radiator 111 and/or the second radiator 121 to resonate, which may include the radio frequency signals received or transmitted by the first feed 112 excite only the first radiator 111 to resonate, and/or the radio frequency signals received or transmitted by the first feed 112 excite only the second radiator 121 to parasitic resonate, and/or the radio frequency signals received or transmitted by the first feed 112 excite the first radiator 111 to resonate and excite the second radiator 121 to parasitic resonate.

Similarly, the radio frequency signals received or transmitted by the second feed 122 may excite the first radiator 111 and/or the second radiator 121 to resonate, including the radio frequency signals received or transmitted by the second feed 122 excite only the second radiator 121 to resonate, and/or the radio frequency signals received or transmitted by the second feed 122 excite only the first radiator 111 to parasitic resonate, and/or the radio frequency signals received or transmitted by the second feed 122 excite the second radiator 121 to resonate and excite the first radiator 111 to parasitic resonate.

With continued reference to fig. 1, the third feed source 123 is connected to the third feeding point G, and the radio frequency signal received or transmitted by the third feed source 123 may excite the second radiator 121 to resonate in the third target frequency band. The third feed 123 corresponds to the antenna ANT3, and the antenna ANT3 has a resonant mode corresponding to a third target frequency band.

Optionally, a third matching circuit M3 may be further disposed between the third feed source 123 and the third feed point G, where the third matching circuit M3 is configured to perform impedance matching on an excitation signal sent by the third feed source 123, so as to excite the second radiator 121 to resonate in a third target frequency band, so that an antenna ANT3 corresponding to the third feed source 123 has a preset S parameter. In addition, the third matching circuit M3 is further configured to filter the radio frequency signal received or transmitted by the third feed source 123.

In some embodiments, as shown in fig. 1, the first ground D may be grounded GND1 through the switch circuit M4, in other words, one end of the switch circuit M4 is connected to the first ground D, and the other end is connected to the ground GND 1.

In some embodiments, the switching circuit M4 may be connected with the motherboard. It is understood that the switching circuit M4 may also be referred to as a matching circuit M4.

The manner in which the first ground terminal D is connected to the ground GND1 and the second ground terminal H is connected to the ground GND2 is not particularly limited in the embodiment of the present application. For example, the connection between the ground terminal D or H and the ground may include, but is not limited to, direct electrical connection (such as soldering), or indirect electrical connection via coaxial lines, microstrip lines, RF lines, conductive clips, conductive adhesives, embedded metal, or a center frame connection of an electronic device in which the antenna assembly is mounted.

In another embodiment, the antenna assembly 10 itself has a reference ground, also referred to as ground pole or ground. Specific forms of the reference ground include, but are not limited to, a metal conductive plate, a metal conductive layer molded into the interior of a flexible circuit board, in a rigid circuit board, and the like. When the antenna assembly 10 is disposed within the electronic device, the reference of the antenna assembly 10 is electrically connected to the reference ground of the electronic device. In other embodiments, the antenna assembly 10 itself does not have a reference ground, and the first ground D of the antenna assembly 10 is electrically connected to the reference ground of the electronic device or the reference ground of the electronics within the electronic device, either by direct electrical connection or indirectly through a conductive member.

In some embodiments, the second target frequency band may include a fourth frequency band, a fifth frequency band, a sixth frequency band, and a seventh frequency band.

The seventh frequency band may be represented by the reference point 8 in fig. 5, where the frequency of the reference point 8 is 7.9069GHz and the radiation efficiency is-17.653 dB.

Accordingly, the antenna ANT2 has a second resonant mode, where the second resonant mode includes a first sub-resonant mode and an eighth sub-resonant mode corresponding to the marking point 1-marking point 8 in fig. 5, and the first sub-resonant mode and the eighth sub-resonant mode are respectively used to support the frequency bands corresponding to the marking point 1-marking point 8.

In some embodiments, the third target frequency band may comprise an LB frequency band. The LB frequency band includes a frequency band less than 1 GHz. For example, as shown in FIG. 7, the LB band may be represented by a mark point 1, the frequency of the mark point 1 is 0.74327GHz, and the radiation efficiency is-10.3748 dB. Accordingly, the antenna ANT3 has a third resonance mode, which is a resonance mode corresponding to the LB frequency band, and the third resonance mode is a 1/4 wavelength mode from the ground GND2 to the slot 13, and is used to support the LB frequency band.

The length of the first radiator 111 and the second radiator 121 is not particularly limited in the embodiment of the present application. As one implementation, the length of the first radiator 111 corresponds to the 1/4 medium wavelength of GPS and the length of the second radiator 121 corresponds to the 1/8-1/4 wavelength of the LB segment.

The antenna assembly 10 has the characteristics of small volume, small occupied space and wide frequency range which can be covered. However, as can be seen from the foregoing, since the first radiator 111 implementing the GPS-L1 band is located at the upper left corner of the electronic device, it is easily blocked by the user's hand, and thus the navigation performance is degraded. Particularly, when the electronic device is a folding electronic device, after the cover is folded, the finger gripping position of the user holding the electronic device can just cover the first radiator 111, so that the navigation communication performance of the folded electronic device can be greatly reduced. Meanwhile, the antenna assembly 10 covers only one navigation band (GPS-L1 band), and has a limited coverage. In summary, the navigation accuracy of the antenna assembly 10 is not high enough, and the navigation communication performance thereof needs to be further improved.

In view of the above, the embodiments of the present application provide a new antenna assembly. The antenna assembly is small in size, occupies small space and can cover a plurality of communication frequency bands, the second radiator for realizing the navigation frequency band in the antenna assembly is positioned on the top wall of the electronic equipment, the problem that a user holds the electronic equipment to shield navigation signals is avoided, and meanwhile, the antenna assembly can cover the first navigation frequency band and the second navigation frequency band at the same time, so that the navigation performance is effectively improved.

The antenna assembly 80 in the embodiment of the present application will be described in detail with reference to fig. 8.

The first antenna element 81 comprises a first radiator 811 and a first feed 812. The second antenna element 82 includes a second radiator 821 and a second feed 822. A slit 83 is formed between the first radiator 811 and the second radiator 821, and the first radiator 811 and the second radiator 821 are coupled through the slit 83 to realize that the first antenna unit 81 and the second antenna unit 82 are a common-caliber common-body antenna.

The second radiator 821 also has a second ground terminal H ', a second free terminal I ', and a second feeding point F '.

The first radiator 811 or the second radiator 821 may have a line with a uniform width on the extended path, or may have a line with a gradual width change and a wide area or the like.

As an example, as shown in fig. 8, the first radiator 811 may have a polygonal line shape folded by 90 degrees. The first ground terminal D 'and the first free terminal C' are both ends of the first radiator 811. The second radiator 821 may have a linear shape. The second ground terminal H 'and the second free terminal I' are both ends of the second radiator 821.

As shown in fig. 20 and 21 hereinafter, the first radiator 811 is arranged to extend from the top wall 21 of the electronic device 20 to the side wall 22 of the electronic device, and the second radiator is arranged only to the top wall 21 of the electronic device 20.

In an embodiment of the present application, the first radiator 811 and/or the second radiator 821 may be formed in any one or more of a flexible circuit board (FPC, flexible Printed Circuit) antenna radiator, a laser direct Structuring (LDS, laser Direct) antenna radiator, a printed direct Structuring (PDS, print Direct) antenna radiator, or a metal bezel.

In some embodiments, as shown in fig. 8, the second antenna element 82 may also include a third feed 823. The third feed 823 is electrically connected with the second radiator 821, and radio frequency signals received or transmitted by the third feed 823 can excite the second radiator 821 to resonate in a third target frequency band. The third feed 823 corresponds to ANT3 'with the antenna ANT3' having a third resonant mode supporting a third target frequency band.

It should be noted that, in the embodiment of the present application, the first target frequency band is a non-navigation frequency band. The type of the first target frequency band is not particularly limited in the embodiment of the application, so long as the first target frequency band is a non-navigation frequency band. In some embodiments, the first target frequency band may include a WIFI5G frequency band. Optionally, the first target frequency band may further comprise a UHB frequency band.

The second target frequency band and the third target frequency band are related frequency bands including navigation frequency bands. In contrast, the second target frequency band includes a first navigation frequency band, the third target frequency band may include a second navigation frequency band, and the second target frequency band may include a non-navigation frequency band in addition to the first navigation frequency band. One of the first navigation frequency band and the second navigation frequency band is a GPS-L1 frequency band, and the other is a GPS-L5 frequency band. In other words, if the first navigation band is the GPS-L1 band, the second navigation band is the GPS-L5 band, otherwise, if the first navigation band is the GPS-L5 band, the second navigation band is the GPS-L1 band. The non-navigation frequency band included in the second target frequency band is not particularly limited in the embodiment of the application. As one implementation, the non-navigational frequency bands of the second target frequency band may include the WIFI2.4G frequency band. As another implementation, the second target frequency band may also include a UHB frequency band at the same time.

From the above, it can be seen that the first target frequency band, the second target frequency band, and the third target frequency band may be a combination of a plurality of different frequency bands. For example, the first target frequency band includes a WIFI5G frequency band+uhb frequency band, the second target frequency band includes a WIFI2.4G frequency band+gps-L1 frequency band, and the third target frequency band includes a GPSL5 frequency band. Or the first target frequency band comprises a WIFI5G frequency band and a UHB frequency band, the second target frequency band comprises a WIFI2.4G frequency band and a GPS-L5 frequency band, and the third target frequency band comprises a GPSL1 frequency band. Or the first target frequency band comprises a WIFI5G frequency band, the second target frequency band comprises WIFI2.4G frequency bands, a GPS-L1 frequency band and a UHB frequency band, and the third target frequency band comprises a GPSL5 frequency band. Or the first target frequency band comprises a WIFI5G frequency band, the second target frequency band comprises WIFI2.4G frequency bands, a GPS-L5 frequency band and a UHB frequency band, and the third target frequency band comprises a GPSL1 frequency band.

By incorporating the implementation of the GPS-L5 band into the implementation branch of the GPS-L1 band, in other words, by using the same branch to generate both the GPS-L1 band and the GPS-L5 band, the antenna assembly 80 can cover more navigation bands, thereby having better navigation performance, and simultaneously improving the radiation efficiency of the GPS-L1 band and the GPS-L5 band.

The embodiment of the present application does not specifically limit the manner in which the third feed 823 is electrically connected to the second radiator 821.

As an implementation manner, as shown in fig. 8, the second radiator 821 further includes a third feeding point G ', where the third feeding point G ' is located between the second feeding point F ' and the second ground H ', and the third feeding source 823 is electrically connected to the second radiator 821 through the third feeding point G '.

The form of the first feeding point E ', the second feeding point F ', or the third feeding point G ' is not particularly limited in the embodiment of the present application. For example, the first feeding point E ' and the second feeding point F ' or the third feeding point G ' may be a welding point or a conductive dome or a conductive paste.

As another implementation, as shown in fig. 19, the third feed 823 is connected to the second radiator 821 through a second feed point F'. That is, the ground triple feed 823 shares a second feed point F' with the second feed 822. By sharing the feed point, one feed point can be saved, wiring of the antenna assembly 80 can be reduced, and space cost and design cost can be reduced.

For ease of understanding, the operating frequency bands and corresponding modes of operation of the antenna assembly 80 are described in exemplary fashion below in connection with fig. 9-12.

In some embodiments, the first target frequency band may include a WIFI5G frequency band. Accordingly, the antenna ANT1 corresponding to the first feed source has a first resonance mode, and the first resonance mode may include a first sub-resonance mode-a third sub-resonance mode supporting the WIFI5G frequency band.

As shown by the arrowed line in fig. 9 (a), the first sub-resonant mode is a 1/4 wavelength mode of the first feed 812 to the slot 83. As shown by the arrowed line in fig. 9 (b), the second sub-resonant mode is a three-quarter wavelength mode from the second ground GND2' to the slot 83, while a strong co-directional current is present through the slot 83 to the first feed 812. As shown by the arrowed line in fig. 9 (c), the third sub-resonant mode is a three-quarter wavelength mode from the second ground GND2' to the slot 83, while there is a strong reverse current flowing through the slot 83 to the first feed 812.

In some embodiments, the first target frequency band or the second target frequency band may further comprise a UHB frequency band. The UHB band may include an N78 band and an N77 band, respectively. Wherein the N78 frequency band is 3.4-3.6GHz frequency band, and the N77 frequency band is 3.3-4.2GHz frequency band. Correspondingly, the antenna ANT1 'corresponding to the first feed source or the antenna ANT2' corresponding to the second feed source has a sixth sub-resonance mode and a seventh sub-resonance mode for supporting the UHB band.

Fig. 9 (d) and 9 (e) show path schematic diagrams of resonant currents when the antenna ANT1' corresponding to the first feed source has a sixth sub-resonance mode and a seventh sub-resonance mode for supporting the UHB band when the first target band includes the UHB band. Specifically, as shown by the arrowed line in fig. 9 (D), the sixth sub-resonant mode is a quarter-wavelength mode from the first ground D' to the slot 83, and a strong current flowing in the same direction passes through the slot 83 to the second feed 822. As shown by the arrowed line in fig. 9 (e), the seventh sub-resonant mode is a quarter wavelength mode from the first ground D' to the slot 83, while there is a stronger reverse current through the slot 83 to the second feed 822.

It will be appreciated that the sixth and seventh sub-resonant modes constitute the E-E radiation mode and the balanced mode. The second and third sub-resonant modes constitute the E-E higher order radiation mode and the balanced mode.

As shown in fig. 10, a simulation diagram of S parameter and efficiency of the antenna ANT1 is shown. The UHB band may be represented by reference point 1 and reference point 2 in fig. 10, and the WIFI5G band may be represented by reference points 3-5 in fig. 10. The frequency of the marking point 1 is 3.0972GHz, the radiation efficiency is-9.9035 dB, the frequency of the marking point 2 is 3.9999GHz, the radiation efficiency is-33.587 dB, the frequency of the marking point 3 is 5.1976GHz, the radiation efficiency is-7.8795 dB, the frequency of the marking point 1 is 5.5103GHz, the radiation efficiency is-7.654 dB, the frequency of the marking point 1 is 5.7935GHz, and the radiation efficiency is-24.769 dB. As can be seen from fig. 10, the efficiency of the higher order mode is higher, and the higher working efficiency is satisfied in the 3-6G band, so that ultra-wideband coverage is realized.

In some embodiments, the second target frequency band may include a GPS-L1 band and a WIFI2.4G band. Corresponding to this, the antenna ANT2' corresponding to the second feed source has a second resonance mode, and the second resonance mode is used for supporting the receiving or transmitting of the second target frequency band. Specifically, the second resonant mode includes a fourth sub-resonant mode and an eighth sub-resonant mode. Wherein the fourth sub-resonance mode is used for supporting the first navigation frequency band and the eighth sub-resonance mode is used for supporting the WIFI2.4G frequency band.

As shown by the arrowed line in fig. 11 (a), the fourth sub-resonance mode is a quarter wavelength mode from the second ground GND2' to the slit 83. As shown by the arrowed line in fig. 11 (b), the eighth sub-resonant mode is a quarter wavelength mode from the first ground GND1' to the slot 83, while a weaker co-current is present through the slot to 83 the second feed 822.

As shown in fig. 12, a simulation diagram of S parameters and efficiency of the antenna ANT2' is shown. Wherein a first navigation band (e.g., GPS-L1 band) is represented by reference point 1 and WIFI2.4G band is represented by reference point 2. The frequency of the marking point 1 is 1.5632GHz, the radiation efficiency is-17.641 dB, the frequency of the marking point 2 is 2.4718GHz, and the radiation efficiency is-21.296 dB.

The antenna component in the embodiment of the application generates the navigation frequency band through the second radiator positioned on the top wall of the electronic equipment and the second feed source connected with the second radiator, so that the receiving position of the navigation signal avoids the hand holding position of a user, thereby avoiding the phenomenon of sudden reduction of the radiation efficiency of the navigation frequency band caused by the grasping of the user and effectively improving the navigation performance of the antenna component. As previously described, the third target frequency band includes the second navigation frequency band. In response thereto, the antenna ANT3' corresponding to the third feed 723 has a third resonant mode including a fifth sub-resonant mode for supporting reception or transmission of the second navigation band.

In the embodiment of the present application, the fifth sub-resonance mode is also a quarter wavelength mode from the second ground GND2' to the slit 83 as shown in fig. 11 (a). That is, the path of the resonance current corresponding to the fifth sub-resonance mode is the same as the path of the resonance current corresponding to the fourth sub-resonance mode.

Fig. 13 is a simulation diagram showing S parameters and efficiency of the antenna ANT 3'. In fig. 13, the second navigation frequency band is taken as an example of the GPS-L5 frequency band, and the GPS-L5 frequency band is denoted by the reference point 1. The frequency of the marking point 1 is 1.1679GHz, and the radiation efficiency is-14.159 dB.

Since paths of resonant currents for supporting the first and second navigation bands are identical, in order to ensure radiation power of the first and second navigation bands, as shown in fig. 8, a third matching circuit M3' may be further provided between the third feed 823 and the second radiator 821. The third matching circuit M3 'is configured to filter out clutter of the excitation signal transmitted by the third feed 823, so as to isolate the first navigation frequency band from the second navigation frequency band, so that a quarter wavelength mode from the second ground GND2' to the slot 83 resonates in the second navigation frequency band. In addition, the third matching circuit M3 'is further configured to perform impedance matching on the excitation signal transmitted by the third feed 823, so as to excite the quarter wavelength mode from the second ground GND2' to the slot 83 to resonate in the second navigation frequency band.

Therefore, although the resonant mode corresponding to the second navigation frequency band is the same as the resonant mode corresponding to the first navigation frequency band, the third matching circuit M3 'can have a stronger adjusting effect on the resonant mode corresponding to the second navigation frequency band, so that the third matching circuit M3' can be isolated and distinguished from the first navigation frequency band.

Optionally, a first matching circuit M1 'may be disposed between the first feed 812 and the first feed point E'. The first matching circuit M1' may be configured to filter clutter of the excitation signal transmitted by the first feed source 812, and may be further configured to perform impedance matching on the excitation signal transmitted by the first feed source, so as to excite the first radiator and/or the second radiator to resonate in the first target frequency band.

Optionally, a second matching circuit M2 'may be provided between the second feed 822 and the second feed point F'. The second matching circuit M2' may be configured to filter clutter of the excitation signal transmitted by the second feed 822, and may be further configured to perform impedance matching on the excitation signal transmitted by the second feed, so as to excite the second radiator and/or the first radiator to resonate in the second target frequency band.

In some embodiments, the first matching circuit M1', the second matching circuit M2', and the third matching circuit M3' may have an isolation function between frequency bands in addition to a filtering function and an impedance matching function.

The structure of the first matching circuit M1', the second matching circuit M2', or the third matching circuit M3' is not particularly limited in the embodiment of the present application. M1', M2', or M3' may include, but is not limited to, series and/or parallel arranged capacitive, inductive, resistive, etc. frequency selective filter networks. In some embodiments, M1', M2', or M3' may include a plurality of branches formed by capacitors, inductors, resistors connected in series and/or parallel, and a switch for controlling the on/off of the plurality of branches. The frequency selection parameters (such as resistance value, inductance value and capacitance value) of the matching circuit can be adjusted by controlling the on-off of different switches, so that the filtering range of the matching circuit is adjusted, and the matching circuit can adjust corresponding radio frequency signals. The different matching circuits may be different, and the specific circuit implementation is not intended to limit the scope of the present application. The matching circuit is used for adjusting the impedance of the radiator electrically connected with the matching circuit, so that the impedance of the radiator electrically connected with the matching circuit is matched with the frequency of resonance generated by the matching circuit, and further, the receiving and transmitting power of the radiator is higher. By setting the matching circuit and adjusting the parameters of the frequency adjusting circuit, the resonant frequency of each antenna can be moved along the low frequency or the high frequency, the ultra-wideband of the antenna assembly 80 is realized, and the coverage and the communication quality of the antenna signals of the antenna assembly 80 are improved.

The first matching circuit M1', the second matching circuit M2', or the third matching circuit M3' may be exemplarily constructed as shown in fig. 14. Wherein the first inductor L1 and the first capacitor C1 are connected in series in FIG. 14 (a), the first inductor L1 and the first capacitor C1 are connected in parallel in FIG. 14 (b), the second capacitor C2 connected in series with the first inductor L1 and the first capacitor C1 in parallel in FIG. 14 (C), the second inductor L2 connected in series with the first inductor L1 and the first capacitor C1 in parallel in FIG. 14 (d), the second capacitor C2 connected in parallel with the first inductor L1 and the first capacitor C1 in series in FIG. 14 (e), the second inductor L2 connected in parallel with the first inductor L1 and the first capacitor C1 in series in FIG. 14 (f), the second inductor L2 and the second capacitor C2 connected in series with the first inductor L1 and the first capacitor C1 in parallel in FIG. 14 (g), and the second inductor L2 and the second capacitor C2 connected in series with the first inductor L1 and the second inductor C1 in parallel in FIG. 14 (h), and the second inductor L2 connected in series with the second inductor L2 and the second capacitor C2. It should be understood that the structure of the first matching circuit M1', the second matching circuit M2', or the third matching circuit M3' is not limited to the structure shown in fig. 14, and may further include a switch or other impedance adjusting element.

In order to verify the operation efficiency of the antenna assembly 80, fig. 15 shows a simulation diagram of S parameters of the antenna ANT1' corresponding to the first feed source, the antenna ANT2' corresponding to the second feed source 822, and the antenna ANT3' corresponding to the third feed source 823 in the antenna assembly 80. Fig. 16 shows a simulation diagram of the system radiation efficiency and the system overall efficiency of the antenna assembly 80 for the antenna ANT1' corresponding to the first feed, the antenna ANT2' corresponding to the second feed 822, and the antenna ANT3' corresponding to the third feed 823.

As shown in fig. 15, the frequency bin generated by the excitation of the antenna ANT1' includes frequency bin 2-frequency bin 6. The frequency of the frequency point 2 is 3.1063GHz, the return loss is-9.881 dB, the frequency of the frequency point 3 is 4GHz, the return loss is-33.534 dB, the frequency of the frequency point 4 is 5.2004GHz, the return loss is-7.877 dB, the frequency of the frequency point 5 is 5.5024GHz, the return loss is-7.6501 dB, the frequency of the frequency point 6 is 5.7886GHz, and the return loss is-24.405 dB. The frequency points generated by excitation of the antenna ANT2' include frequency points 7-8. Wherein, the frequency of the frequency point 7 is 1.5633GHz, the return loss is-17.549 dB, the frequency of the frequency point 8 is 2.4714GHz, and the return loss is-21.267 dB. The frequency point generated by excitation of the antenna ANT3' is frequency point 1, the frequency of the frequency point 1 is 1.1679GHz, and the return loss is-14.159 dB.

As shown in fig. 16, the frequency bin generated by the excitation of the antenna ANT1' includes frequency bins 2-4. The frequency of the frequency point 2 is 3.5079GHz, the total efficiency of the system is-2.8759 dB, the frequency of the frequency point 3 is 5.2687GHz, the total efficiency of the system is-3.3078 dB, the frequency of the frequency point 4 is 5.7009GHz, and the total efficiency of the system is-3.4689 dB. The frequency points generated by excitation of the antenna ANT2' include frequency points 5-6. The frequency of the frequency point 5 is 1.56GHz, the total efficiency of the system is-4.305 dB, the frequency of the frequency point 6 is 2.449GHz, and the total efficiency of the system is-3.0182 dB. The frequency point generated by excitation of the antenna ANT3' is frequency point 1, the frequency of the frequency point 1 is 1.18GHz, and the total efficiency of the system is-6.3786 dB. Therefore, the total system efficiency of the first target frequency band excited by the antenna ANT1' is between-2 dB and-4 dB, and the radiation efficiency is high. The total system efficiency of the second target frequency band excited by the antenna ANT2' is between-3 dB and-5 dB, and the radiation efficiency is also high. Meanwhile, the total system efficiency of the LB frequency band excited by the antenna ANT3' is about-6 dB, and the radiation efficiency is higher.

As can be seen from fig. 15 and fig. 16, after the GPS-L5 band is combined into the branch of the GPS-L1 band in the antenna assembly 80 according to the embodiment of the present application, the original bands of WIFI2.4G, WIFI5G, N78, etc. can still be reserved, and the radiation efficiency thereof is not reduced. Meanwhile, the performance of the GPS-L1 frequency band and the GPS-L5 frequency band in the free scene is also reserved. In addition, since the second radiator 821 implementing the GPS-L5 band and the GPS-L1 band is located on the top wall, i.e., the lateral short side, of the electronic device 20, the influence of the user's grip on the navigation band can be avoided. This advantage is particularly pronounced in a foldable electronic device 20 that can maintain good performance of closed-cover talk and closed-cover navigation in a hand-held scenario after closing the cover. Because the GPS-L1 frequency band and the GPS-L5 frequency band cannot be held, the performance resident in a closed-cover scene is realized, and the function of closed-cover navigation is favorably ensured.

In addition, the paths of the resonant currents corresponding to the GPS-L1 frequency band and the GPS-L5 frequency band in the embodiment of the application are the same, so that the GPS-L1 frequency band and the GPS-L5 frequency band both have very high upper hemisphere duty ratio, and the navigation communication performance is further ensured.

To verify the upper hemisphere duty cycle of the GPS-L1 band and the GPS-L5 band in the antenna assembly 80, fig. 17 and 18 show simulated diagrams of the upper hemisphere duty cycle of the GPS-L1 band and the GPS-L5 band in the antenna assembly 80, respectively.

As shown in fig. 17, the total 3D radiation efficiency of the GPS-L1 band is 0.031375839dB, the 3D radiation efficiency of the upper hemisphere is 0.017263043dB, and the 3D radiation efficiency of the lower hemisphere is 0.014112797dB. Therefore, the upper hemisphere of the GPS-L1 band is 55% and thus the upper hemisphere of the GPS-L1 band is very high.

As shown in fig. 18, the total 3D radiation efficiency of the GPS-L5 band is 0.011611791dB, the 3D radiation efficiency of the upper hemisphere is 0.0060605275dB, and the 3D radiation efficiency of the lower hemisphere is 0.0055512635dB. Therefore, the upper hemisphere of the GPS-L5 band has a 52% duty cycle and also has an upper hemisphere duty cycle exceeding 50%, and therefore the upper hemisphere duty cycle of the GPS-L5 band is also high.

The embodiment of the present application further provides an electronic device 20, where the antenna assembly 80 may be applied to the electronic device 20, that is, the electronic device 20 includes any of the antenna assemblies 80 described above.

The type of the electronic device 20 is not particularly limited in the embodiment of the present application, as long as the electronic device 150 needs to implement the wireless communication function through the antenna assembly. The electronic device may be, for example, a cellular telephone, a cordless telephone, a session initiation protocol (session initiation protocol) telephone, a wireless local loop (wireless local loop, WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a learning or electronic dictionary, and a smart watch. Preferably, the electronic device is a foldable electronic device. For example, the electronic device may be an electronic device capable of forming a small screen after being folded up and down. The folded small screen may also be referred to as a secondary screen.

As shown in fig. 20 and 21, the electronic device 20 may include a top wall 21 and side walls 22 on both sides of the top wall. As shown in fig. 2, the sidewalls are a first sidewall 221 on the left side and a second sidewall 222 on the right side. Wherein the first sidewall 221 and the second sidewall 222 are areas for gripping. The first radiator 811 is arranged to extend from the top wall 21 of the electronic device 20 to the side wall 221 of the electronic device 20, and the second radiator 821 is arranged to the top wall 21 of the electronic device. Thus avoiding that a user may block the signal from the antenna assembly 80 when holding the electronic device 20.
