Description

Technical Field

[0001] The present invention relates to an antenna structure, and particularly to a three-dimensional antenna and an electronic device having the three-dimensional antenna. Background Art

[0002] Currently, with the popularization of full-screen, curved-screen, etc., the available clearance for antennas is getting less and less. And due to the increase in 5G and 6G NR frequency bands currently, the number of antennas is actually more compared with 4G LTE, resulting in difficult antenna layout and reduced efficiency. Currently, metal frame antennas are usually adopted to solve the problems of more antenna requirements and less clearance. However, due to appearance requirements, many slots cannot be opened in the metal antennas, resulting in a limited number of antennas that can be made on the frame. Therefore, in addition to the metal frame antennas, other antennas need to be added to meet the antenna number requirements without affecting the screen-to-body ratio. Summary of the Invention

[0003] An object of the present invention is to provide a three-dimensional antenna and an electronic device having the three-dimensional antenna to solve the above problems.

[0004] To solve the above technical problems, on the one hand, an electronic device is provided. The electronic device includes a rear case and a three-dimensional antenna. The electronic device further includes a three-dimensional antenna. The three-dimensional antenna includes a suspended antenna body, an antenna bracket, and branch antenna bodies provided on at least one side of the antenna bracket. Wherein, the suspended antenna body is provided on the rear case, the antenna bracket is close to the rear case and is spaced from the rear case, and the branch antenna bodies are coupled with the suspended antenna body.

[0005] On the other hand, a three-dimensional antenna is provided, which is applied to an electronic device. The three-dimensional antenna includes a suspended antenna body, an antenna bracket, and branch antenna bodies provided on at least one side of the antenna bracket. The suspended antenna body is used to be provided on the rear case of the electronic device. Wherein, the antenna bracket is close to the rear case and is spaced from the rear case.

[0006] The three-dimensional antenna and the electronic device provided by the present invention form a three-dimensional antenna by coupling the suspended antenna body and the branch antenna bodies on the rear case. Since the rear case is far from the internal components of the electronic device, a good clearance environment can be ensured, and the antenna signals of the corresponding frequencies supported by the branch antenna bodies are strengthened, effectively improving the overall antenna performance.

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0016] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "thickness" is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than implying or indicating that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0017] Please refer to Figure 1 and Figure 2 , Figure 1Schematic cross-sectional view of a partial area of the electronic device 100 in an embodiment of the present application. Figure 2 Simplified schematic diagram of the three-dimensional antenna 20 in an embodiment of the present application. As Figure 1 and Figure 2 shown, the electronic device 100 includes a rear housing 10 and a three-dimensional antenna 20. The three-dimensional antenna 20 includes a suspended antenna body 21, an antenna support 22, and branch antenna bodies 23 provided on at least one side of the antenna support 22. Among them, the suspended antenna body 21 is provided on the rear housing 10, the antenna support 22 is close to the rear housing 10 and is spaced from the rear housing 10, and the branch antenna bodies 23 are coupled to the suspended antenna body 21.

[0018] In the present application, a three-dimensional antenna is formed by coupling the suspended antenna body 21 and the branch antenna bodies 23 on the rear housing 10. Since the rear housing 10 is far from the internal components of the electronic device 100, a good clearance environment can be ensured, and the antenna signals of the corresponding frequencies supported by the branch antenna bodies 23 can be strengthened, effectively improving the overall antenna performance of the three-dimensional antenna 20.

[0019] Among them, the antenna support 22 and the branch antenna bodies 23 of the three-dimensional antenna 20 are provided inside the electronic device 100, and the antenna support 22 and the branch antenna bodies 23 of the three-dimensional antenna 20 are provided on one side of the inner surface of the rear housing 10.

[0020] As Figure 1 shown, the antenna support 22 includes a first surface S1 facing the rear housing 10 and a second surface S2 opposite to the first surface S1, and the branch antenna bodies 23 are provided on at least one of the first surface S1 and the second surface S2. That is, the branch antenna bodies 23 can be two, respectively provided on the first surface S1 of the antenna support 22 facing the rear housing 10 and the second surface S2 facing away from the rear housing 10; the branch antenna bodies 23 can also be one, provided on the first surface S1 of the antenna support 22 facing the rear housing 10 or the second surface S2 facing away from the rear housing 10.

[0021] Among them, the antenna support 22 is a plate-shaped support extending along the surface of the rear housing, and the first surface S1 and the second surface S2 are two opposite surfaces of the antenna support 22 parallel to the surface of the rear housing.

[0022] Among them, the surface of the rear housing refers to the surface of the rear housing 10 that serves as the back of the electronic device 100, and is also the surface of the rear housing 10 parallel to the display screen plane of the electronic device.

[0023] Among them, the antenna bracket 22 is a plate-shaped bracket that is generally flat, and the first surface S1 and the second surface S2 are two flat surfaces, that is, the two surfaces with the largest dimensions of the antenna bracket 22.

[0024] In one embodiment, as Figure 1 shown, the number of the branch antenna bodies 23 is two, including a first branch antenna body 231 and a second branch antenna body 232. The first branch antenna body 231 is disposed on the first surface S1 of the antenna bracket 22, and the second branch antenna body 232 is disposed on the second surface S2 of the antenna bracket 22. The first branch antenna body 231 and the second branch antenna body 232 form a coupled antenna.

[0025] Furthermore, as Figure 2 shown, a feeding point F1 is provided on the second branch antenna body 232. The feeding point F1 divides the second branch antenna body 232 into a first branch portion B1 and a second branch portion B2. The first branch portion B1 is used to support the transceiver of antenna signals of the first frequency, and the second branch portion B2 is coupled with the first branch antenna body 231 to support the transceiver of antenna signals of the second frequency.

[0026] That is, the part from one end D1 of the second branch antenna body 232 to the feeding point F1 is the first branch portion B1, and the part between the other end D2 of the second branch antenna body 232 and the feeding point F1 is the second branch portion B2. The feeding point F1 is used to connect with a feed source for feeding. In fact, the feeding point F1 divides the second branch antenna body 232 into the first branch portion B1 and the second branch portion B2.

[0027] The first branch portion B1 independently supports the transceiver of antenna signals of the first frequency, that is, the electronic device 100 can receive and send antenna signals of the first frequency. The second branch portion B2 is coupled with the first branch antenna body 231 to support the transceiver of antenna signals of the second frequency. That is, after the second branch portion B2 is coupled with the first branch antenna body 231, a coupled antenna is formed, and the electronic device 100 can receive and send antenna signals of the second frequency. Among them, the first frequency and the second frequency are different.

[0028] For example, the first frequency can be a frequency in the WIFI band, and the second frequency can be a frequency in the 5G band, and so on.

[0029] Among them, the length of the first branch portion B1 is 1 / 4 wavelength of the antenna signal of the first frequency it supports. That is, the length from one end D1 of the second branch antenna body 232 to the feeding point F1 is 1 / 4 of the wavelength of the antenna signal of the first frequency supported by the first branch portion B1.

[0030] The length of the first branch antenna body 231 is 1 / 2 wavelength of the antenna signal of the supported second frequency, that is, 1 / 2 of the wavelength of the antenna signal of the supported second frequency.

[0031] Although the second branch part B2 is coupled with the first branch antenna body 231 to support the transceiver of the antenna signal of the second frequency, in this application, the transceiver of the antenna signal of the second frequency can be mainly relied on the first branch antenna body 231. Therefore, the length of the first branch antenna body 231 needs to satisfy 1 / 2 of the wavelength of the antenna signal of the second frequency it supports. The length of the second branch part B2 can be appropriately set according to the supported second frequency. Specifically, the length of the second branch part B2 only needs to meet the requirement of improving the transceiver performance of the antenna signal of the second frequency. For example, the length of the second branch part B2 can be 1 / 3, 1 / 4, etc. of the wavelength of the antenna signal of the supported second frequency.

[0032] In this embodiment, the length of the floating antenna body 21 is an integer multiple of 1 / 2 wavelength of the antenna signal of the first frequency or the antenna signal of the second frequency. That is, the length of the floating antenna body 21 can be an integer multiple of 1 / 2 of the wavelength of the antenna signal of the first frequency or the antenna signal of the second frequency. For example, the length of the floating antenna body 21 is 1 / 2 of the wavelength of the antenna signal of the first frequency or the antenna signal of the second frequency, or equal to the wavelength of the antenna signal of the first frequency, etc.

[0033] When the length of the floating antenna body 21 is an integer multiple of 1 / 2 wavelength of the antenna signal of the first frequency, the floating antenna body 21 is coupled with the first branch part B1, and can effectively improve the intensity of the antenna signal of the first frequency and improve the transceiver performance of the antenna body for the antenna signal of the first frequency. In addition, although the length of the floating antenna body 21 is not an integer multiple of 1 / 2 wavelength of the antenna signal of the second frequency at this time, it can still improve the intensity of the antenna signal of the second frequency to a certain extent and improve the transceiver performance of the antenna signal of the second frequency. Therefore, when the length of the floating antenna body 21 is an integer multiple of 1 / 2 wavelength of the antenna signal of the first frequency, it can significantly improve the transceiver performance of the antenna signal of the first frequency and can also improve the transceiver performance of the antenna signal of the second frequency to a certain extent.

[0034] Similarly, when the length of the floating antenna body 21 is an integer multiple of 1 / 2 wavelength of the antenna signal of the second frequency, the floating antenna body 21 is coupled with the coupled antenna formed by coupling the second branch portion B2 and the first branch antenna body 231, and can effectively improve the intensity of the antenna signal of the second frequency, and improve the transceiver performance of the antenna signal of the second frequency. In addition, although the length of the floating antenna body 21 is not an integer multiple of 1 / 2 wavelength of the antenna signal of the first frequency at this time, it can still improve the intensity of the antenna signal of the first frequency to a certain extent, and improve the transceiver performance of the antenna signal of the first frequency. Therefore, when the length of the floating antenna body 21 is an integer multiple of 1 / 2 wavelength of the antenna signal of the second frequency, the transceiver performance of the antenna signal of the second frequency can be significantly improved, and the transceiver performance of the antenna signal of the first frequency can also be improved to a certain extent.

[0035] Therefore, in the present application, by providing the floating antenna body 21 on the rear case 10, the antenna performance of the branch antenna body 23 for transceiving the antenna signals of all supported frequencies can be improved, but the improvement degree is different.

[0036] For example, in some embodiments, the length of the floating antenna body 21 can be set according to the frequency frequently used by the electronic device 100. For example, when the antenna signal of the first frequency is the frequently used antenna signal, the length of the floating antenna body 21 can be set to an integer multiple of 1 / 2 wavelength of the antenna signal of the first frequency, and the transceiver performance of the antenna signal of the first frequency can be significantly improved.

[0037] A grounding point G1 is provided on the second branch portion B2, and the grounding point G1 is used for grounding. The grounding point is the grounding point of the entire three-dimensional antenna 20.

[0038] As described above, the feeding point F1 is provided on the second branch antenna body 232, and the second branch antenna body 232 is divided into a first branch portion B1 and a second branch portion B2. That is, the feeding point F1 is provided at the junction of the first branch portion B1 and the second branch portion B2. The feeding point F1 is the feeding point of the entire three-dimensional antenna 20. The first branch antenna body 231 and the floating antenna body 21 are both fed by a coupling method, and no feeding point and grounding point are provided on the first branch antenna body 231 and the floating antenna body 21.

[0039] As Figure 1 and Figure 2 shown, the projections of the first branch antenna body 231 and the second branch antenna body 232 on the antenna bracket 22 partially overlap.

[0040] Further, as shown in Figure 1 and Figure 2 , the projection of the first branch antenna body 231 on the antenna bracket 22 only partially overlaps with the projection of the second branch portion B2 of the second branch antenna body 232 on the antenna bracket 22. That is, a part of the first branch antenna body 231 faces a part of the second branch portion B2 of the second branch antenna body 232 in the direction from the antenna bracket 22 to the rear case. The first branch antenna body 231 and the second branch portion B2 can be coupled through the mutually facing parts.

[0041] As shown in Figure 2 , the projection of the floating antenna body 21 on the antenna bracket 22 at least partially overlaps with the projections of the first branch antenna body 231 and the second branch antenna body 232 on the antenna bracket 22.

[0042] Among them, the extending directions of the first branch antenna body 231, the second branch antenna body 232, and the floating antenna body 21 are the same.

[0043] Please refer to Figure 3 , which is a cross-sectional schematic diagram of a partial area of the electronic device 100 in another embodiment of the present application.

[0044] As shown in Figure 3 , in another embodiment, the number of the branch antenna bodies 23 is one. The branch antenna body 23 is disposed on the first surface S1 of the antenna bracket 22. A feeding point F2 and a grounding point G2 are provided on the branch antenna body 23. The branch antenna body 23 at least supports the transceiver of antenna signals of a third frequency.

[0045] Among them, according to the different positions of the feeding point F2 provided on the branch antenna body 23, the branch antenna body can realize the transceiver of antenna signals of one or more frequencies. For example, when the feeding point F2 is provided at one end of the branch antenna body 23 or near one end, the transceiver of antenna signals of one frequency can be realized. When the feeding point F2 is provided at a position farther from the end of the branch antenna body 23, the branch antenna body 23 can also be divided into two branch portions as described above, and the transceiver of antenna signals of two frequencies can be realized.

[0046] Among them, the third frequency is different from the foregoing first frequency and second frequency, or can also be the same as the foregoing first frequency or second frequency.

[0047] Among them, the length of the floating antenna body 21 is an integer multiple of 1 / 2 wavelength of the antenna signal of the third frequency, that is, the length of the floating antenna body 21 is an integer multiple of 1 / 2 of the wavelength of the antenna signal of the third frequency. Thus, the floating antenna body 21 is coupled with the branch antenna body 23, effectively improving the performance of receiving and transmitting the antenna signal of the third frequency.

[0048] Please refer to Figure 4 , which is a schematic cross-sectional view of a partial area of the electronic device 100 in another embodiment of the present application.

[0049] As Figure 4 shown, in another embodiment, the number of the branch antenna bodies 23 is also one. The branch antenna body 23 is disposed on the second surface S2 of the antenna bracket 22. A feeding point F3 and a grounding point G3 are provided on the branch antenna body 23. The branch antenna body 23 at least supports the receiving and transmitting of the antenna signal of the fourth frequency.

[0050] Similarly, according to the different positions of the feeding point F3 disposed on the branch antenna body 23, the branch antenna body can realize the receiving and transmitting of the antenna signal of one or more frequencies. For example, when the feeding point F3 is disposed at one end of the branch antenna body 23 or near one end, the receiving and transmitting of the antenna signal of one frequency can be realized. When the feeding point F3 is disposed at a position far from the end of the branch antenna body 23, the branch antenna body 23 can also be divided into two branch parts as described above, realizing the receiving and transmitting of the antenna signal of two frequencies.

[0051] Among them, the fourth frequency is different from the foregoing first frequency, second frequency, and third frequency, or can also be the same as one of the foregoing first frequency, second frequency, and third frequency.

[0052] Among them, in this embodiment, the length of the floating antenna body 21 is an integer multiple of 1 / 2 wavelength of the antenna signal of the fourth frequency, that is, the length of the floating antenna body 21 is an integer multiple of 1 / 2 of the wavelength of the antenna signal of the fourth frequency. Thus, the floating antenna body 21 is coupled with the branch antenna body 23, effectively improving the performance of receiving and transmitting the antenna signal of the third frequency.

[0053] Among them, as Figures 1-4 shown, the electronic device 100 further includes a PCB (printed circuit board) 30. The PCB 30 is disposed on one side of the second surface S2 of the antenna bracket 22. That is, the PCB 30 faces the second surface S2 of the antenna bracket, and the second surface S2 faces the PCB 30.

[0054] In some embodiments, the antenna bracket 22 is a pressing plate bracket disposed between the PCB board 30 and the rear case 10. While serving as the antenna bracket 22, it is also used to press and fix a specific component J1 on the PCB board 30.

[0055] Among them, the specific component J1 can be a component such as a BTO (board to board) connector disposed on the PCB board 30 that requires further pressing and fixing to ensure firm fixation.

[0056] That is, the antenna bracket 22 is a pressing plate bracket that shares the PCB board 30, thereby effectively reducing the thickness of the electronic device 100.

[0057] Among them, as Figure 1 shown in the figures, one end 221 of the antenna bracket 22 also extends to the board surface S3 of the PCB board 30 facing / opposite to the second surface S2 and is fixed to the board surface S3. A protruding portion T1 is provided on one side of the other end 221 of the antenna bracket 22 facing the PCB board 30, and the protruding portion T1 is used to press and fix the specific component J1 disposed on the PCB board 30.

[0058] Among them, the antenna bracket 22 can be made of materials such as resin and plastic, and the end 221 of the antenna bracket 22 can be fixed to the PCB board 30 by means of clamping or the like.

[0059] Among them, the aforementioned feeding points F1 to F3 are connected to the feed source 31 disposed on the PCB board 30 through the feeding connection member C1, and the aforementioned grounding points G1 to G3 are connected to the ground on the PCB board 30 through the grounding connection member C2.

[0060] Specifically, in one embodiment, as Figure 1 shown, when the branch antenna body 23 includes a first branch antenna body 231 and a second branch antenna body, and the feeding point F1 is disposed on the second branch antenna body 232 and the grounding point G1 is disposed on the second branch portion B2 of the second branch antenna body 232, the feeding point F1 can be directly connected to the feed source 31 disposed on the PCB board 30 through the feeding connection member C1, and the grounding point G1 can also be directly connected to the ground point G0 on the PCB board 30 through the grounding connection member C2.

[0061] As Figure 3As shown, in another embodiment, when the branch antenna body 23 includes only one, and the one branch antenna body 23 is arranged on the first surface S1 of the antenna bracket 22, the feeding point F2 and the grounding point G2 are both arranged on the branch antenna body 23 located on the first surface S1 of the antenna bracket 22, the antenna bracket 22 is further provided with a first through hole K1 and a second through hole K2 passing through the first surface S1 and the second surface S2.

[0062] In which, the feeding point F2 and the grounding point G2 of the branch antenna body 23 are both facing the first surface S1 side and are respectively opposite to the first through hole K1 and the second through hole K2, one end of the feeding connector C1 is electrically connected to the feed source 31, and the other end passes through the first through hole K1 and is electrically connected to the feeding point F2, one end of the grounding connector C2 is electrically connected to the ground of the PCB board 30, and the other end passes through the second through hole K2 and is electrically connected to the grounding point G2.

[0063] In some embodiments, the first through hole K1 and the second through hole K2 may be conductive through holes. One end of the feed connector C1 is electrically connected to the feed source 31, and the other end is connected to one end of the first through hole K1. The other end of the first through hole K1 is electrically in contact with the feed point F2, thereby establishing an electrical connection between the feed point F2 and the feed source 31. One end of the ground connector C2 is electrically connected to the ground of the PCB board 30, and the other end is connected to one end of the second through hole K2. The other end of the second through hole K2 is electrically in contact with the ground point G2, thereby establishing an electrical connection between the ground point G2 and the ground.

[0064] like Figure 4 As shown, in another embodiment, when the branch antenna body 23 includes only one, and the one branch antenna body 23 is disposed on the second surface S2 of the antenna support 22, Figure 1 The embodiment shown is the same. Since the branch antenna body 23 is arranged on the second surface S2 of the antenna bracket 22 and is opposite to the PCB board 30, the feeding point F3 can be directly connected to the feed source 31 arranged on the PCB board 30 through the feeding connector C1, and the grounding point G3 can also be directly connected to the ground on the PCB board 30 through the grounding connector C2.

[0065] The feed source 31 and the ground can be arranged on the surface S3 of the PCB board 30 facing the antenna support 22, or on the surface of the PCB board 30 facing away from the antenna support 22. When the feed source 31 and the ground are arranged on the surface of the PCB board 30 facing away from the antenna support 22, the connection between the feed source 31 and the feed connector C1, and the connection between the ground and the ground connector C2 can also be achieved by means of through holes.

[0066] Among them, the feeding connector C1 and the grounding connector C2 can be electrical connectors such as metal spring pieces, flexible circuit boards, wires, etc.

[0067] Among them, the PCB board 30 can be the main board of the electronic device 100.

[0068] Among them, there is a gap between the two branch antenna bodies 23 including the first branch antenna body 231 and the second branch antenna body 232 or the single branch antenna body 23 and the PCB board 30 or the rear shell 10 / floating antenna body 21, and the gap can be a value such as 0.15 mm.

[0069] In this application, the two branch antenna bodies 23 including the first branch antenna body 231 and the second branch antenna body 232 or the single branch antenna body 23 and the floating antenna body 21 in the above embodiments can be respectively formed on the antenna bracket 22 and the rear shell 10 by means of LDS (Laser Direct Structuring), silver paste printing, etc., or can also be metal sheets such as copper foils or FPCs attached to the antenna bracket 22 and the rear shell 10.

[0070] As Figures 1-4 shown, the floating antenna body 21 is disposed on the inner surface of the rear shell 10.

[0071] Please refer to Figure 5 , which is a cross-sectional schematic view of a partial area of the electronic device 100 in other embodiments. As Figure 5 shown, the floating antenna body 21 can also be disposed on the outer surface of the rear shell 10.

[0072] That is, in this application, the floating antenna body 21 can be disposed on the inner surface or the outer surface of the rear shell 10.

[0073] Among them, the inner surface of the rear shell 10 refers to the surface of the rear shell 10 located inside the electronic device 100, and the outer surface of the rear shell 10 refers to the exposed back surface of the electronic device 100.

[0074] Please refer to Figure 6 , which is a planar schematic view showing a partial internal structure of the electronic device 100 in an embodiment of this application. As Figure 6 shown, the electronic device 100 is generally a cuboid, and the three-dimensional antenna 20 is disposed at a vertex region of the electronic device 100.

[0075] That is, in one embodiment, the number of the three-dimensional antennas 20 can be one, and it is disposed at a vertex region of the electronic device 100.

[0076] Thus, by disposing the three-dimensional antenna 20 at the vertex angle region of the electronic device 100, it can be a certain distance away from the components and the PCB board 30 inside the electronic device 100, reducing interference to the antenna.

[0077] Among them, as Figure 6 shown, the branch antenna body 23 and the floating antenna body 21 can be generally strip-shaped antennas, and the length directions of the branch antenna body 23 and the floating antenna body 21, that is, the extending directions of the long sides of the branch antenna body 23 and the floating antenna body 21, are parallel to the long side of the electronic device 100.

[0078] Please refer to Figure 7 , which is a schematic plan view showing a partial internal structure of the electronic device 100 in another embodiment of the present application. In another embodiment, the number of the three-dimensional antennas 20 can be multiple, and the multiple three-dimensional antennas 20 are respectively disposed at different vertex angles of the electronic device 100.

[0079] For example, as Figure 7 shown, the number of the three-dimensional antennas 20 is two, which are respectively disposed at two adjacent vertex angle regions of the electronic device 100.

[0080] Among them, the structure of each three-dimensional antenna 20 can be the structure in any of the foregoing embodiments. In some embodiments, the structures of each three-dimensional antenna 20 can be the same. For example, it is the structure in a certain foregoing embodiment. In some embodiments, the structures of different three-dimensional antennas 20 can also be different. For example, one of the three-dimensional antennas 20 can be Figure 1 the structure in the shown embodiment, while the other three-dimensional antenna 20 is the structure in another embodiment shown in Figure 3 .

[0081] Thus, by disposing the three-dimensional antennas 20 at different vertex angle regions, the antenna frequencies / bands that can be increased by the electronic device 100 can be further increased, further meeting the requirements for the number of antennas in current 5G NR and 6G NR.

[0082] Among them, the electronic device 100 may further include structures such as a display screen and a glass cover plate, which are not described and illustrated because they are not related to the improvement of the present invention. For example, Figure 1 the cross-sectional view shown in the figure is a schematic view after removing the structures such as the display screen and the glass cover plate, only schematically showing the component structures involved in the present invention.

[0083] Among them, the electronic device 100 can be a mobile phone or a tablet computer.

[0084] The electronic device 100 and the three-dimensional antenna 20 provided by the present invention form a three-dimensional antenna through the coupling of the suspended antenna body 21 and the branch antenna body 23 provided on the rear shell 10. Since the rear shell 10 is far from the internal components of the electronic device 100, a good clearance environment can be ensured, and the antenna signals of the corresponding frequencies supported by the branch antenna body 23 can be strengthened, effectively improving the overall antenna performance of the three-dimensional antenna 20.

[0085] The above is the implementation manner of the embodiments of the present invention.
