Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

FIG. 1 is a schematic structural diagram 1 of an antenna module according to an exemplary embodiment. As shown in Figure 1, the antenna module includes:

Radiation structure 101;

the first feeding point 102, connected with the radiation structure, and combined with the radiation structure to transmit the wireless signal of the first frequency;

The second feeding point 103 is connected to the radiation structure and is provided separately from the first feeding point; wherein, the second feeding point is combined with the radiation structure to transmit the wireless signal of the second frequency; the second frequency is not equal to the first frequency .

In the embodiment of the present disclosure, the antenna module can realize communication between devices, and is widely used in terminal devices such as smart phones and smart watches.

The above-mentioned radiation structure is used for transmitting or receiving wireless signals. The radiation structure may be a structure formed by a flexible printed circuit (FPC) or a structure formed by a laser direct structuring (LDS). Of course, in the embodiment of the present disclosure, the conductive frame of the terminal device can also be directly used as the radiation structure, which can reduce the space occupied by the radiation structure of the terminal device.

It should be noted that when the radiation structure is a structure formed by FPC and the antenna module is set on a smartphone, the radiation structure can be located between the printed circuit board and the back cover of the terminal device; when the radiation structure is a structure formed by LDS , and when the antenna module is arranged on the terminal device, the radiation structure can be plated on the middle frame or rear shell of the smartphone through LDS.

The above-mentioned first feeding point and second feeding point can both be set on a circuit board, and the circuit board includes but is not limited to a printed circuit board (Printed Circuit Board, PCB) of a terminal device.

It should be noted that both the first feeding point and the second feeding point can transmit the first electrical signal generated by the radio frequency front-end component of the antenna module to the radiation structure, so that the radiation structure can radiate wireless radiation under the excitation of the first electrical signal. Alternatively, after the radiation structure converts the received wireless signal into a second electrical signal, the second electrical signal can be transmitted to the RF front-end component of the antenna module to implement subsequent processing such as wireless signal reception and signal decoding.

In the embodiment of the present disclosure, the first feeding point and the second feeding point are provided separately, and the two feeding points are feeding points for transmitting signals of different frequencies. For example, the first feed point is a feed point for transmitting frequencies in the GPS L5 frequency band, and the second feed point is a feed point for transmitting frequencies in the Sub-6GHz frequency band; or, the first feed point is for transmission in the Sub-6GHz frequency band. The mid-frequency feed point, and the second feed point is the feed point for transmitting the mid-frequency frequency of the GPS, which is not limited in the embodiment of the present disclosure.

In the embodiment of the present disclosure, the first feeding point is combined with the radiation structure to transmit the wireless signal of the first frequency.

Exemplarily, the first frequency may be a frequency in the range of 2515MHz-2675MHz corresponding to the N41 frequency band, a frequency in the range of 3400MHz-3600MHz corresponding to the N78 frequency band, or a frequency in the range of 4800MHz-4900MHz corresponding to the N79 frequency band. .

In the embodiment of the present disclosure, the second feeding point is combined with the radiation structure to transmit the wireless signal of the second frequency.

Exemplarily, the second frequency may be a frequency within the range of 1176.45MHz±1.023MHz corresponding to the GPS L5 frequency band.

Through the embodiments of the present disclosure, on the one hand, the two feeding points can share the radiation structure, so that the antenna module can simultaneously transmit and receive wireless signals of frequencies in different frequency bands. On the other hand, the embodiment of the present disclosure does not need to separately set the radiation structure corresponding to the first frequency and the radiation structure corresponding to the second frequency, which can reduce the number of radiation structures to be set, thereby reducing the space occupied by the antenna module of the terminal device, and improving the Space utilization of terminal equipment.

In some embodiments, as shown in Figure 2, the radiation structure includes:

The first radiator 101b is connected to the first feeding point and the second feeding point respectively;

The second radiator 101a is separated from and opposite to the first radiator, and is coupled with the first radiator;

Wherein, the first radiator, the second radiator and the first feeding point are combined to transmit the wireless signal of the first frequency; the first radiator and the second feeding point are combined to transmit the wireless signal of the second frequency.

In the embodiment of the present disclosure, the first radiator is a part of the radiation structure shared by the first feeding point and the second feeding point. In the radiation structure, in the process of using the first radiator or the combination of the first radiator and the second radiator for signal transmission, the combined length of the first radiator and the second radiator is greater than the length of the first radiator. That is, the length of the radiator can be changed by using different combinations. The length of the radiator is related to the wavelength of the radiation. Therefore, the transmission and reception of wireless signals of different frequencies can be realized according to whether the second radiator participates in radiation.

It should be noted that the first frequency is greater than the second frequency. Through the coupling of the first radiator and the second radiator, an additional high-frequency mode can be added to expand the frequency at which the antenna module can send and receive wireless signals, so that the antenna module can send and receive higher-frequency wireless signals.

In some embodiments, as shown in FIG. 3 , the antenna module further includes:

The first filtering network 104 is connected to the first feeding point 102, and is used for passing the first frequency wireless signal in the wireless signal when the radiation structure receives the wireless signal;

The second filtering network 105 is connected to the second feeding point 103, and is used for passing the second frequency wireless signal in the wireless signal when the radiation structure receives the wireless signal.

It should be noted that, in the process of transmitting and receiving wireless signals by sharing a radiation structure between two feeding points, the electrical signal converted by the radiation structure is transmitted to the radio frequency of the antenna module through the first feeding point and the second feeding point. Front-end components will interact with each other, resulting in low isolation between signals. Based on this, the embodiment of the present disclosure sets a first filter network and a second filter network, so that the first filter network passes the first frequency wireless signal to filter out the second frequency wireless signal; the second filter network passes the second frequency wireless signal, filters except the first frequency wireless signal. In this way, it can reduce the mutual influence between the signals when the two feed points share a radiation structure and can simultaneously send and receive wireless signals, effectively increase the isolation between the signals, and enable the antenna module to better realize the simultaneous sending and receiving of wireless signals. .

In the embodiment of the present disclosure, the first filter network and the second filter network may be set according to the characteristics of different frequencies of the wireless signals sent and received. When the first frequency is greater than the second frequency, the first filter network can be set as a high-pass filter network that filters out wireless signals lower than the first frequency, and the second filter network can be set as a low-pass filter network that filters out wireless signals higher than the second frequency network. In this way, based on the first filtering network and the second filtering network, the wireless signals of the frequencies that generate interference can be filtered out, which greatly reduces the interference between the signals.

It should be noted that the first filter network and the second filter network may be composed of inductors and/or capacitors. For example, the first filter network and the second filter network can be formed by the formation of parallel capacitors or series inductors. The first filter network and the second filter network can also be formed by a notch filter, which is used to eliminate signals of unwanted frequencies in the circuit.

In the embodiment of the present disclosure, the two filtering networks are designed to filter out signals of different frequencies. When both filter networks are LC circuits and the first frequency is greater than the second frequency, the inductor and capacitor in the first filter network can be connected in series and the inductor is grounded; the inductor and capacitor in the second filter network can be connected in series and the capacitor is grounded, At the same time, the inductance and/or capacitance values in the first filter network are different. For example, the capacitance value in the first filter network is greater than the capacitance value in the second filter network. When both filter networks are composed of notch filters, and the first frequency is greater than the second frequency, the stopband cutoff frequency of the first filter network can be set to be lower than the stopband cutoff frequency of the second filter network.

In some embodiments, as shown in FIG. 4 , the antenna module further includes:

a first radio frequency front-end component 107;

The first impedance matching network 106 is connected between the first filtering network 104 and the first RF front-end component 107, and has an impedance within a preset range together with the first feeding point and the first RF front-end component;

In this way, the embodiment of the present disclosure uses the first impedance matching network, so that the energy generated by the first radio frequency front-end component can be radiated to the greatest extent through the radiation structure, thereby reducing transmission damage and improving the transceiving efficiency of the first frequency.

In the embodiment of the present disclosure, when the output impedance of the first RF front-end component is 50 ohms, the first impedance matching network may use a Smith chart matching element to match the impedance of the first frequency to 50 ohms in the Smith chart near the area. In this way, it can be achieved that the energy generated by the first radio frequency front-end component can be radiated out through the radiation structure to the greatest extent. It should be noted that the network structure of the first impedance matching network is not fixed, as long as the impedance of the first frequency can be matched to the vicinity of the 50 ohm region in the Smith chart.

Exemplarily, the preset range can be set according to actual needs, for example, the preset range can be set to be in the range of 90 ohms to 110 ohms.

It should be noted that FIG. 4 is only an exemplary embodiment of the present disclosure, and the impedance matching network and filtering network of the embodiment of the present disclosure are not limited to the connection devices and connection relationships in FIG. 4 , as long as the impedance matching network of the present application can be realized and filter network requirements. Exemplarily, in FIG. 4 , C1 may be 2.5F, C2 may be 5.2F, C3 may be 0.5F, and C4 may be 0.5F; L1 may be 25H, L2 may be 35H, L3 may be 5.1H, and L4 may be 3.5H.

In some embodiments, the antenna module further includes:

a second radio frequency front-end component;

The second impedance matching network is connected between the second filter network and the second radio frequency front-end component, and has an impedance within a preset range together with the second feeding point and the second radio frequency front-end component.

In this way, the embodiment of the present disclosure uses the second impedance matching network, so that the energy generated by the second RF front-end component can be radiated to the greatest extent through the radiation structure, thereby reducing transmission damage and improving the transceiver efficiency of the second frequency.

In the embodiment of the present disclosure, when the output impedance of the second RF front-end component is 50 ohms, the second impedance matching network may use a Smith chart matching element to match the impedance of the second frequency to 50 ohms in the Smith chart near the area. In this way, it can be achieved that the energy generated by the second radio frequency front-end component can be radiated out through the radiation structure to the greatest extent. It should be noted that the network structure of the second impedance matching network is not fixed, as long as the impedance of the second frequency can be matched to the vicinity of the 50 ohm region in the Smith chart.

As shown in Figure 5, the abscissa is the frequency, and the unit is GHz; the ordinate is the return loss, and the unit is dB. The solid line S11 is the return loss curve of sending and receiving wireless signals of the second frequency after the second impedance matching network and the second filter network are set on the antenna module; S12 is the setting of the first impedance matching network and the first filter on the antenna module. The return loss curve of sending and receiving wireless signals of the first frequency after the network; S22 is the isolation curve between the signals when the corresponding impedance matching network and filter network are set for the antenna module when sending and receiving wireless signals at the same time. It can be seen from Figure 5 that the antenna module can achieve good impedance matching for both sending and receiving wireless signals of the first frequency and the second frequency, so that the return loss of sending and receiving wireless signals of the first frequency and the second frequency is close to 0; In addition, the isolation degree between signals in the isolation degree curve can be lower than 17.8dB, which greatly reduces the influence of the radiation structure when transmitting and receiving wireless signals of two frequencies at the same time.

FIG. 6 is an antenna efficiency diagram of the antenna module for transmitting and receiving wireless signals of the second frequency; FIG. 7 is an antenna efficiency diagram of the antenna module transmitting and receiving wireless signals of the first frequency. The solid line represents the radiation efficiency of the antenna module, and the dashed line represents the total efficiency of the antenna module. It can be seen from FIG. 6 that the total efficiency of the antenna module for sending and receiving wireless signals of the second frequency can reach -5.45dB, which meets the performance requirements of the antenna module for sending and receiving the second frequency. It can be seen from Figure 7 that the total efficiency of the first frequency in the N41 frequency band, the N78 frequency band and the N79 frequency band can all be above -3dB, which also meets the performance requirements of the antenna module for transmitting and receiving the first frequency.
