The technical solution of the present invention will be further described with reference to the following embodiments and the accompanying drawings.
Referring to fig. 2 and 3, an embodiment of the present invention discloses an antenna assembly 100, which can be applied to a capsule endoscope. The antenna assembly 100 comprises a bearing plate 1, an antenna 2 and a metal piece 3, wherein the bearing plate 1 is provided with a first bearing surface 11, a second bearing surface 12 and an outer peripheral surface 13, the first bearing surface 11 and the second bearing surface 12 are oppositely arranged, the outer peripheral surface 13 is connected to the first bearing surface 11 and the second bearing surface 12, the antenna 2 is arranged on the first bearing surface 11, the antenna 2 is used for being electrically connected with a radio frequency end of a main board of the capsule endoscope, the metal piece 3 is arranged on the outer peripheral surface 13 and/or the second bearing surface 12 of the bearing plate 1, and the metal piece 3 is electrically connected with the antenna 2 so that the metal piece 3 can be used as an extension section of the antenna 2.
That is, in the antenna assembly 100 provided in the present application, the metal piece 3 electrically connected to the antenna 2 is disposed on the outer peripheral surface 13 and/or the second bearing surface 12 of the bearing plate 1, so that the metal piece 3 can be used as an extended antenna of the antenna 2, and thus the total length of the antenna 2 can be increased, and the transmission performance of the antenna 2 can be enhanced, which is beneficial to greatly improving the transmission effect and stability of the antenna 2, and further beneficial to effectively improving the performance of the capsule endoscope.
Further, the antenna assembly 100 provided by the present application utilizes the space of the outer peripheral surface 13 or the second bearing surface 12 of the bearing plate 1 to extend the length of the antenna 2, so that the transmission performance of the antenna 2 can be improved and the signal receiving effect of the antenna 2 can be improved without changing the size of the bearing plate 1.
As can be seen from the foregoing, the metal member 3 is disposed on the outer peripheral surface 13 and/or the second bearing surface 12, that is, only the outer peripheral surface 13 of the bearing plate 1 may be disposed with the metal member 3; alternatively, only the second bearing surface 12 of the bearing plate 1 can be provided with the metal piece 3; or, the metal piece 3 is arranged on both the outer peripheral surface 13 and the second bearing surface 12 of the bearing plate 1. It will be understood that, depending on the position of the metal element 3, the electrical connection between the metal element 3 and the antenna 2 may be different, in particular:
for a first example, when the metal part 3 is disposed on the outer peripheral surface 13 of the carrier board 1, the antenna 2 may extend to the outer peripheral surface 13 to be electrically connected to the metal part 3, so that the metal part 3 may serve as an extension of the antenna 2. The electrical connection is simple and convenient, and the antenna assembly 100 is easier to process and assemble.
As a second example, when the metal component 3 is disposed on the second carrying surface 12 of the carrying board 1, the antenna assembly 100 may further include a conductive component (not shown), which may be disposed on the outer peripheral surface 13, and the conductive component is electrically connected to the metal component 3 and the antenna 2, respectively, so as to achieve electrical connection between the antenna 2 and the metal component 3, so that the metal component 3 may serve as an extension of the antenna 2. By arranging the metal piece 3 on the second bearing surface 12, the metal piece is beneficial to having a longer length, so that the antenna 2 after being lengthened is beneficial to ensuring a longer total length, and thus the transmission performance of the antenna 2 can be effectively enhanced.
It will be appreciated that in the second example, in addition to the electrical connection between the antenna 2 and the metallic piece 3 that can be achieved in the above-described manner, the following can be implemented: the loading board 1 may be provided with a through hole penetrating through the first loading surface 11 and the second loading surface 12, the conductive member is disposed in the through hole, and both ends of the conductive member extend to the outside of the through hole respectively and are electrically connected with the metal member 3 and the antenna 2, so as to realize the electrical connection between the antenna 2 and the metal member 3.
In a third example, when the metal member 3 is disposed on both the outer peripheral surface 13 and the second bearing surface 12 of the carrier plate 1, in this example, the metal member 3 disposed on the outer peripheral surface 13 is electrically connected to the metal member 3 disposed on the second bearing surface 12, wherein the metal member 3 disposed on the outer peripheral surface 13 and the metal member 3 disposed on the second bearing surface 12 may be integrally formed or may be separately formed, which is not limited herein. Moreover, the antenna 2 extends to the outer peripheral surface 13 and is electrically connected with the metal part 3 arranged on the outer peripheral surface 13, so that the metal part 3 arranged on the outer peripheral surface 13 and the second bearing surface 12 can be used as an extension section of the antenna 2, thus the electrical connection mode between the metal part 3 and the antenna 2 is simpler and more convenient, and the processing and the assembly of the antenna component 100 are easier; meanwhile, the metal piece 3 can have a longer total length, so that the antenna 2 after being lengthened can have a longer total length, and the transmission performance of the antenna 2 can be enhanced more effectively.
In some embodiments, the metal piece 3 may have a sheet-like structure, and occupies a small internal space of the capsule endoscope, so that by disposing the metal piece 3 on the outer circumferential surface 13 or the second bearing surface 12 of the bearing plate 1, the length of the antenna 2 can be extended without changing the size of the bearing plate 1, so as to improve the transmission performance of the antenna 2, and at the same time, the size of the capsule endoscope cannot be made larger, that is, the length of the antenna 2 can be extended to enhance the transmission performance of the antenna 2, and it is still beneficial to make the capsule endoscope conform to a miniaturized design.
Illustratively, the material of the metal piece 3 may be any one of copper, silver, nickel and titanium, or any one of copper alloy, silver alloy, nickel alloy and titanium alloy.

In some embodiments, the carrier Board 1 may be a rigid Circuit Board (PCB). Compared with a Flexible Circuit board (FPC), the bearing plate 1 is a hard Circuit board, and the hard Circuit board has certain strength to bear the antenna 2 and the metal piece 3, so that the bearing plate 1 is not easy to deform and avoid warping, and the antenna 2 and the metal piece 3 are protected from being broken easily.
It can be known that the thickness of the hard circuit board is generally 0.8mm to 6.4mm, and the thickness of the flexible circuit board is generally 0.1mm to 0.2mm, so that the thickness of the flexible circuit board is generally thinner than that of the hard circuit board, and therefore, compared with the use of the flexible circuit board and the hard circuit board, the hard circuit board is beneficial to enabling the peripheral surface 13 of the bearing surface to have a larger area, so that the metal piece 3 is easier and more convenient to arrange.
Further, the bearing plate 1 may be a circular bearing plate, an oval bearing plate, or a polygonal bearing plate, etc., and the embodiment is not limited thereto.
It will be appreciated that the carrier plate 1 will normally be provided with other electronic components such as resistors, capacitors, etc. in addition to the antenna 2. In order to avoid the interference of the other electronic components with the signal of the antenna 2, the other electronic components are usually disposed on the second carrying surface 12 of the carrying board 1. Similarly, in order to reduce the signal interference caused by the other electronic components to the extended antenna (i.e. the metal component 3) as the antenna 2, as shown in fig. 4, in this application, it is preferable that the metal component 3 is disposed on the outer peripheral surface 13 of the carrier board 1, in this case, the metal component 3 may be disposed around the outer peripheral surface 13 of the carrier board 1, and the metal component 3 has a first end 31 and a second end 32, and any one of the first end 31 and the second end 32 is electrically connected to the antenna 2, for example, the first end 31 is electrically connected to the antenna 2, or the second end 32 is electrically connected to the antenna 2. Through setting up metalwork 3 at the outer peripheral face 13 of loading board 1 for other electronic components such as metalwork 3 and resistance, electric capacity set up on the different faces of loading board 1, thereby be favorable to avoiding other electronic components such as resistance, electric capacity to the signal production interference of antenna 2 after the extension, with the working property of guaranteeing antenna 2 after the extension.
Moreover, compared with the method of only disposing the metal member 3 on the second carrying surface 12, the method of disposing the metal member 3 on the outer peripheral surface 13 is adopted, and when the electrical connection between the metal member and the antenna is realized, no additional conductive member needs to be disposed, and no through hole needs to be formed in the carrying plate, so that the electrical connection method is simpler and more convenient, and the processing and the assembly of the antenna assembly 100 are easier.
In addition, the metal part 3 is constructed to surround the outer peripheral surface 13 of the bearing plate 1, so that the metal part 3 can have a longer length while the interference of other electronic components on the signal of the extended antenna 2 is avoided, the extended antenna 2 can have a longer total length, and the transmission performance of the antenna 2 can be effectively enhanced.
Illustratively, the metal member 3 may be an open-loop structure surrounding the outer circumferential surface 13, and the metal member 3 is provided with a gap 33, and the gap 33 is used for spacing the metal member to form the first end 31 and the second end 32. In this way, by configuring the metal part 3 to be an open-loop structure surrounding the outer peripheral surface 13, the area of the outer peripheral surface 13 can be fully utilized by the metal part 3, so that the metal part 3 can be ensured to have a longer length, and the extended antenna 2 can be ensured to have a longer total length, which can be more beneficial to effectively enhance the transmission performance of the antenna 2.
In some embodiments, the length of the indentation 33 in the circumferential direction of the carrier plate 1, e.g. in the direction indicated by the arrow x in fig. 4, is 0.2cm to 0.5cm, i.e. the distance between the first end 31 and the second end 32 of the metal piece 3 is 0.2cm to 0.5cm, e.g. 0.2cm, 0.25cm, 0.3cm, 0.35cm, 0.4cm, 0.45cm or 0.5cm, etc. Through the length control with breach 33 at 0.2cm ~ 0.5 cm's within range, can guarantee that metalwork 3 has longer length simultaneously, avoid metalwork 3's first end 31 and second end 32 to leave too closely, thereby be favorable to avoiding appearing leading to antenna 2 simultaneously and the condition of first end 31 and second end 32 electricity connection because of the distance is too close between first end 31 and the second end 32, and then be favorable to guaranteeing that antenna 2 after the extension can launch signal and received signal, can normally work.
In order to effectively utilize the area of the first bearing surface 11 to arrange the antenna 2 as long as possible, as an alternative embodiment, as shown in fig. 5, the antenna 2 may be arranged on the first bearing surface 11 in a spiral or zigzag shape. The adoption is the antenna 2 that is the heliciform or the shape of returning to the form, is favorable to satisfying the miniaturized design of loading board 1 simultaneously for antenna 2 has longer length, thereby is favorable to making the antenna 2 after the extension have longer total length, is favorable to strengthening antenna 2's transmission performance effectively like this.
In this embodiment, the antennas 2 may be arranged in a spiral or zigzag shape with the center of the first supporting surface 11 as the arrangement center. Therefore, the longer antenna 2 can be arranged by utilizing the area of the first bearing surface 11 as much as possible, so that the antenna 2 can be favorably used for a smaller bearing plate 1 when the same length requirement is met, namely, the longer antenna 2 can be favorably arranged on the smaller bearing plate 1, and the miniaturization design of the capsule endoscope is further favorably realized.
Further, as shown in fig. 5, the antennas 2 are arranged in a spiral or zigzag shape with the center of the first supporting surface 11 as the arrangement center, and the shape of the antennas 2 is adapted to the shape of the supporting plate 1, for example, as shown in (a) of fig. 5, if the supporting plate 1 is circular, the shape of the antennas 2 on the first supporting surface 11 of the supporting plate 1 is spiral. For another example, as shown in fig. 5 (b), if the shape of the carrier board 1 is square, the shape of the antenna 2 on the first bearing surface 11 of the carrier board 1 is an approximately square shape. For another example, as shown in fig. 5 (c), if the shape of the carrier board 1 is pentagonal, the shape of the antenna 2 on the first bearing surface 11 of the carrier board 1 is an approximate pentagonal loop shape. In this way, the effective space of the carrier plate 1 is utilized to the maximum, the length of the antenna 2 can be further increased, and the signal receiving effect of the antenna 2 is further improved. It is understood that, in other embodiments, the antennas 2 are arranged in a spiral or zigzag shape with the center of the first bearing surface 11 as the arrangement center, but the shape of the antennas 2 is not matched with the shape of the carrier board 1, for example, as shown in (a) and (b) of fig. 6.
It should be noted that the shapes of the carrier plate 1 are circular, square and pentagonal, which is only exemplary, and in practice, the shape of the carrier plate 1 can also be arranged as hexagonal, heptagonal or octagonal, etc., and then the shape of the antenna 2 on the carrier plate 1 is an approximate hexagonal loop shape, heptagonal loop shape or octagonal loop shape, etc. Here, the shape of the carrier board 1 is not particularly limited, and the shape of the antenna 2 on the first carrying surface 11 of the carrier board 1 is not particularly limited.
As another alternative, as shown in fig. 7, the antenna 2 may be disposed on the first bearing surface 11 in a bent shape. Adopt to be the antenna 2 of bending form, be favorable to satisfying the miniaturized design of loading board 1 simultaneously for antenna 2 has longer length, thereby is favorable to making the antenna 2 after the extension have longer total length, is favorable to strengthening antenna 2's transmission performance effectively like this.
In this embodiment mode, the antenna 2 may extend from one side of the carrier board 1 to the other side of the carrier board 1. Therefore, the longer antenna 2 can be arranged by utilizing the area of the first bearing surface 11 as much as possible, so that the antenna 2 can be favorably used for a smaller bearing plate 1 when the same length requirement is met, namely, the longer antenna 2 can be favorably arranged on the smaller bearing plate 1, and the miniaturization design of the capsule endoscope is further favorably realized.
In a first example, as shown in fig. 7 (a), the antenna 2 is disposed on the first supporting surface 11 of the supporting plate 1 in a sawtooth wave shape, and the sawtooth wave shaped antenna 2 extends from one side of the supporting plate 1 to the other side of the supporting plate 1.
In a second example, as shown in fig. 7 (b), the antenna 2 is disposed on the first supporting surface 11 of the supporting plate 1 in a square wave shape, and the square wave shaped antenna 2 extends from one side of the supporting plate 1 to the other side of the supporting plate 1.
