Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an antenna assembly and an electronic device. Background Art

[0002] The router is usually provided with an antenna assembly, which can transmit and receive signals. The antenna assembly usually includes two 2G antennas and two 5G antennas.

[0003] In the related art, the antenna assembly is obtained by cutting, bending and other processes on a complete sheet metal, wherein the two 2G antennas and the two 5G antennas are both bent portions formed by bending the sheet metal. Since the 2G antenna and the 5G antenna are both made of the same sheet metal, the two 2G antennas are functionally dependent on each other, and the two 5G antennas are functionally dependent on each other. Therefore, the two 2G antennas can only provide one feeding point for the antenna assembly, and the two 5G antennas can only provide one feeding point for the antenna assembly. In this way, the antenna assembly has two feeding points. In other words, the number of feeding points of the antenna assembly is different from the number of antennas of the antenna assembly. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides an antenna assembly and an electronic device, which can make the number of feeding points of the antenna assembly the same as the number of antennas.

[0005] In a first aspect of the present application, an antenna assembly is provided, comprising: an insulating support and at least two antennas. The at least two antennas are respectively fixed on the insulating support, and there is a gap between any two antennas. In other words, the at least two antennas are dispersedly fixed on the insulating support. Thus, the function of each antenna is relatively independent, and each antenna can provide a feeding point for the antenna assembly. Therefore, the number of feeding points of the antenna assembly is the same as the number of antennas.

[0006] Regarding the number of antennas, in one possible implementation, the antenna assembly includes four antennas, namely a first antenna, a second antenna, a third antenna and a fourth antenna, and the first antenna, the second antenna, the third antenna and the fourth antenna provide four feeding points for the antenna assembly. In other words, the antenna assembly has four feeding points, so that the antenna assembly can realize the function of four feeds. In electronic devices such as routers, four RF front-end modules are usually included, namely two 2G RF front-end modules and two 5G RF front-end modules. Each RF front-end module is electrically connected to the antenna assembly via a feeder. Compared with an antenna assembly with two feeding points, when the antenna assembly of the present application has four feeding points, the number of feeding points is the same as the number of RF front-end modules, and each RF front-end module can be connected to the corresponding feeding point via a feeder, without the need for a duplexer to combine the signal, thereby reducing the cost of the electronic equipment.

[0007] In another possible implementation, the antenna assembly may include two antennas, and the antenna assembly has two feeding points. Alternatively, the antenna assembly may include three antennas, and the antenna assembly has three feeding points. Alternatively, the antenna assembly may include five antennas, and the antenna assembly has five feeding points. Of course, the antenna assembly may also include a greater number of antennas.

[0008] With respect to the operating frequency bands of each antenna, in a possible implementation, the operating frequency band of the first antenna may be the same as the operating frequency band of the second antenna, the operating frequency band of the third antenna may be the same as the operating frequency band of the fourth antenna, and the operating frequency bands of the third antenna and the fourth antenna are both lower than the operating frequency bands of the first antenna and the second antenna. In one example, the first antenna and the second antenna are both 5G antennas, and the third antenna and the fourth antenna are both 2G antennas. In another example, the first antenna and the second antenna are both 2G antennas, and the third antenna and the fourth antenna are both 5G antennas. Thus, the operating frequency band of the antenna assembly includes two operating frequency bands, so that the antenna assembly can realize the function of dual-frequency quad-feed.

[0009] Based on this, the polarization directions of the first antenna and the second antenna are different. In this way, the antenna assembly can realize the dual-polarization function, that is, the antenna assembly of the present application can realize the dual-frequency four-feed dual-polarization function, thereby improving the throughput of the antenna assembly.

[0010] In another possible implementation, the first antenna, the second antenna, and the third antenna have the same operating frequency band, and the fourth antenna has a different operating frequency band from the first antenna. Exemplarily, the first antenna, the second antenna, and the third antenna are all 5G antennas, and the fourth antenna is a 2G antenna; or, the first antenna, the second antenna, and the third antenna are all 2G antennas, and the fourth antenna is a 5G antenna.

[0011] Regarding the structure of the insulating support body, in a possible implementation, the insulating support body includes a first support plate and a second support plate fixed to the first support plate, and an angle is formed between the second support plate and the first support plate. In one example, the end of the second support plate is fixedly connected to the end of the first support plate, whereby the insulating support body can form an "L"-shaped structure. In another example, the second support plate is fixed to the middle of the first support plate, whereby the insulating support body can form a "T"-shaped structure. Compared with a flat insulating support body, the insulating support body of the present application has a higher strength.

[0012] At least two antennas may be fixed on the insulating support body respectively. Some of the at least two antennas are fixed on the first support plate, and the other antennas are fixed on the second support plate. In this way, the number of antennas fixed on the first support plate or the second support plate is small, thereby increasing the distance between antennas fixed on the same support plate, thereby reducing signal interference between antennas fixed on the same support plate, thereby improving antenna isolation.

[0013] Exemplarily, the first antenna, the second antenna, the third antenna, and the fourth antenna may all be plate-shaped structures. The first antenna and the second antenna are fixed to the first support plate, and the third antenna and the fourth antenna are fixed to the second support plate. Of course, in other embodiments, the first antenna and the third antenna are fixed to the first support plate, and the second antenna and the fourth antenna are fixed to the second support plate.

[0014] Furthermore, the antenna assembly further comprises a decoupling portion, which can be fixed on the insulating support body and is located between the third antenna and the fourth antenna. In this way, the decoupling portion can reduce the coupling between the signal of the third antenna and the signal of the fourth antenna, thereby further improving the antenna isolation.

[0015] Furthermore, the second support plate includes a first surface, and the third antenna, the decoupling portion, and the fourth antenna are fixed to the first surface at intervals. In this way, there is a distance between the third antenna and the decoupling portion, and there is a distance between the decoupling portion and the fourth antenna, thereby further improving the decoupling effect of the decoupling portion on the third antenna and the fourth antenna.

[0016] With respect to the structure of the insulating support body, in another possible implementation, the insulating support body includes a first support plate and a second support plate and a third support plate fixed on the first support plate, and the second support plate is arranged opposite to the third support plate. The second support plate and the third support plate are fixed to the same board surface of the first support plate. In one example, the second support plate and the third support plate are fixed to both ends of the same board surface of the first support plate. In this case, the insulating support body can form an approximately "U"-shaped structure. In another example, the second support plate and the third support plate are fixed to the same board surface of the first support plate, and are at a certain distance from both ends of the board surface. Thus, the first support plate, the second support plate and the third support plate can form a frame structure, thereby making the strength of the insulating support body higher.

[0017] Based on this, the third antenna and the fourth antenna may adopt the above-mentioned plate-like structure; or, the third antenna and the fourth antenna may also be an "L"-shaped structure, for example, the third antenna and the fourth antenna may each include a first substrate and a second substrate that are connected and have an angle. The first substrates of the third antenna and the fourth antenna are both fixed on the first support plate, and the second substrates of the third antenna and the fourth antenna are both fixed on the second support plate. In this way, the third antenna is fixedly connected to the two support plates of the insulating support body, thereby making the connection strength between the third antenna and the insulating support body higher. The fourth antenna is also fixedly connected to the two support plates of the insulating support body, thereby making the connection strength between the fourth antenna and the insulating support body higher. On this basis, the decoupling part is fixed on the first support plate or the second support plate, and is located between the third antenna and the fourth antenna, thereby, the decoupling part can still improve the antenna isolation.

[0018] Regarding the connection relationship between the third antenna and the fourth antenna and the insulating support body, in one example, a through hole is provided on one end of the first support plate close to the second support plate, and the first substrates of the third antenna and the fourth antenna are fixed to the surface of the first support plate facing away from the second support plate. Parts of the second substrates of the third antenna and the fourth antenna are both located in the through hole, and the other parts extend out of the through hole, and the second substrates of the third antenna and the fourth antenna are fixed to the surface of the second support plate facing the third support plate. In this way, part of the third antenna is fixed to the second support plate in an embedded manner, thereby further improving the connection strength between the third antenna and the second support plate, that is, improving the connection strength between the third antenna and the insulating support body. Similarly, the connection strength between the fourth antenna and the insulating support body can also be improved.

[0019] Furthermore, the first substrates of the third antenna and the fourth antenna are both fixed to the surface of the first support plate facing away from the second support plate, and the second substrates of the third antenna and the fourth antenna are both fixed to the surface of the second support plate facing away from the third support plate. The inner side and the outer side of the insulating support body can be defined here, and a receiving space can be formed between the second support plate and the third support plate of the insulating support body. The receiving space can be the inner side of the insulating support body, and the side opposite to the inner side is the outer side. In other words, the third antenna and the fourth antenna are both fixed to the outer side of the insulating support body.

[0020] The antenna assembly of this application can be manufactured in the following two ways:

[0021] First, each antenna can be made by stamping, machining, etc. Each antenna is placed in a mold, and injection molding is performed in the mold to form an insulating support body, and an antenna assembly is produced. The insulating support body can be an insulating material such as plastic, and each antenna is connected to the insulating support body after the injection molding is completed. Since the third antenna and the fourth antenna are both fixed to the outside of the insulating support body, when the third antenna and the fourth antenna are placed in the mold before injection molding, the third antenna and the fourth antenna can be placed on the inner wall of the mold, thereby facilitating the fixing of the third antenna and the fourth antenna in the mold.

[0022] The second method is to first make an insulating support by injection molding. The area on the insulating support where the antenna is set is metallized to form each antenna and to make an antenna assembly. When the third antenna and the fourth antenna are both fixed to the outside of the insulating support, it is convenient to make the third antenna and the fourth antenna by metallization.

[0023] In a second aspect of the present application, an electronic device is provided, comprising a circuit board and an antenna assembly according to any one of the above embodiments, wherein the antenna assembly is fixed on the circuit board. The electronic device can achieve all the effects of the antenna assembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The term "and / or" herein is merely a description of the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone, wherein A and B may be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one (item)" refers to one or more, and "plurality" refers to two or more. "At least one of the following (items)" or similar expressions refers to any combination of these items, including any combination of single (items) or plural (items). For example, at least one (item) of a, b or c may represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", wherein a, b, c may be single or multiple.

[0042] The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects rather than to describe a specific order of objects. For example, a first target object and a second target object are used to distinguish different target objects rather than to describe a specific order of target objects.

[0043] "Connected", "connected" and similar words are used to express the intercommunication or interaction between different components, which may include direct connection or indirect connection through other components. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, inclusion of a series of steps or units. Methods, systems, products or devices are not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices. "Up", "down", "left", "right" and the like are only used relative to the orientation of the components in the drawings. These directional terms are relative concepts. They are used for description and clarification relative to the description, which may change accordingly according to the change of the orientation of the components in the drawings.

[0044] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0045] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more than two. For example, multiple processing units refer to two or more processing units; multiple systems refer to two or more systems.

[0046] In order to facilitate the understanding of the antenna assembly of this application, the technical terms are first explained:

[0047] Antenna: An electronic device used to transmit or receive radio waves or electromagnetic waves.

[0048] Antenna throughput: refers to the amount of data successfully transmitted per unit time to a network, device, port, virtual circuit or other facility.

[0049] Antenna isolation: The ratio of the power of the signal transmitted by one antenna to the power of the signal received by another antenna.

[0050] Feed point of antenna: The location on the antenna that is connected to the feeder line, used to send signals transmitted from the antenna to the feeder line, and vice versa.

[0051] like Figure 1 As shown, the electronic device 1 generally includes an antenna assembly 20, and the antenna assembly 20 is used to send and receive signals. Since 5G communication has the advantages of large communication capacity and strong signal, the antenna assembly 20 generally includes a 5G antenna. However, the wall penetration effect of 5G signals is poor. Therefore, in order to improve the wall penetration effect of the signal received or sent by the electronic device 1, the antenna assembly 20 also includes a 2G antenna. Here, the electronic device 1 can be a router, a mobile phone, a tablet computer, a wearable device, an augmented reality (AR) device, a laptop computer, a super mobile personal computer (personal digital assistant, PDA), etc.

[0052] At present, the electronic device 1 is required to have the function of dual-frequency quad-feed. Therefore, the antenna assembly 20 includes two 2G antennas and two 5G antennas. In the related art, the antenna assembly 20 is obtained by cutting, bending and other processes on a complete sheet metal, wherein the two 2G antennas and the two 5G antennas are the bending parts formed after the sheet metal is bent. However, the operating frequency bands of the 2G antenna and the 5G antenna are different, that is, the antenna assembly 20 has two operating frequency bands. Moreover, the 2G antenna and the 5G antenna are made of the same sheet metal, the two 2G antennas are functionally dependent on each other, and the two 5G antennas are functionally dependent on each other, thus, the two 2G antennas can only provide one feeding point for the antenna assembly 20, and the two 5G antennas can only provide one feeding point for the antenna assembly 20, so that the antenna assembly 20 has two feeding points. Thus, the antenna assembly 20 can realize the function of dual-frequency dual feeding. It can be seen that in the related art, the number of feeding points of the antenna assembly 20 is different from the number of antennas of the antenna assembly 20.

[0053] In order to achieve functional integration, such as Figure 1As shown, the electronic device 1 generally includes two 2G RF front-end modules (FEM) 13, two 5G FEMs 14, and four filters 12. The two 2G FEMs 13 and the two 5G FEMs 14 are electrically connected to each filter 12, respectively. Since the antenna assembly 20 has two feeding points, the electronic device 1 includes two feed lines 11. In this way, the number of feed lines 11 is different from the number of filters 12, so it is necessary to add a duplexer 15 to the link. The duplexer 15 has two input ports, wherein the output ports of the two filters 12 are electrically connected to the two input ports of a duplexer 15, respectively, and the output port of the duplexer 15 is electrically connected to a feeding point of the antenna assembly 20 through the feed line 11. This will increase the cost of the electronic device 1.

[0054] If the link between the FEM and the antenna assembly 20 is an active link, such as Figure 1 As shown, the electronic device 1 further includes two switch converters 16 , one end of the switch converter 16 is electrically connected to the output port of the duplexer 15 , and the other end of the switch converter 16 is electrically connected to the feeder 11 .

[0055] Based on this, Figure 2 As shown, an embodiment of the present application provides an antenna assembly 20, and the antenna assembly 20 includes: an insulating support 21 and at least two antennas 22. At least two antennas 22 are respectively fixed on the insulating support 21, and there is a gap between any two antennas 22. In other words, at least two antennas 22 are dispersedly fixed on the insulating support 21. As a result, the function of each antenna 22 is relatively independent, and each antenna 22 can provide a feeding point for the antenna assembly 20. Therefore, the number of feeding points of the antenna assembly 20 is the same as the number of antennas 22.

[0056] like Figure 2 As shown, the insulating support body 21 includes a first support plate 211 and a second support plate 212 and a third support plate 213 fixed on the first support plate 211, and the second support plate 212 is arranged opposite to the third support plate 213. In this embodiment, the first support plate 211, the second support plate 212 and the third support plate 213 are all flat plate structures, so that each antenna 22 is easily fixed on the insulating support body 21. In other embodiments, the first support plate 211, the second support plate 212 and the third support plate 213 may also be arc plate structures.

[0057] like Figure 2 As shown, the second support plate 212 and the third support plate 213 are both fixed to the same plate surface of the first support plate 211 .

[0058] In one example, if Figure 2 and Figure 3As shown, the second support plate 212 and the third support plate 213 are fixed to two ends of the same plate surface 2111 of the first support plate 211. In this case, the insulating support body 21 can form an approximately "U"-shaped structure.

[0059] In another example, Figure 3 As shown, the second support plate 212 and the third support plate 213 are fixed to the same plate surface 2111 on the first support plate 211, and there is a certain distance between the second support plate 212 and the first end 2112 of the plate surface 2111, and there is a certain distance between the third support plate 213 and the second end 2113 of the plate surface 2111.

[0060] like Figure 3 and Figure 5 As shown, the insulating support body 21 composed of the first support plate 211, the second support plate 212 and the third support plate 213 may be a frame structure, so that the strength of the insulating support body 21 is higher. The material of the insulating support body 21 may be an insulating material such as plastic.

[0061] Regarding the number of antennas 22, in a possible implementation manner, as shown in FIG. Figure 6 As shown, the antenna assembly 20 includes four antennas 22, namely, a first antenna 221, a second antenna 222, a third antenna 223 and a fourth antenna 224. The first antenna 221, the second antenna 222, the third antenna 223 and the fourth antenna 224 are respectively fixed on the insulating support 21, so that the functions of the first antenna 221, the second antenna 222, the third antenna 223 and the fourth antenna 224 are relatively independent, and each antenna 22 can provide a feeding point for the antenna assembly 20, that is, the first antenna 221, the second antenna 222, the third antenna 223 and the fourth antenna 224 can provide four feeding points for the antenna assembly 20. Then, the antenna assembly 20 of this embodiment has four feeding points, so that the antenna assembly 20 can realize the function of four feeds.

[0062] like Figure 7 As shown, when Figure 2 When the antenna assembly 20 shown is applied to the electronic device 1, since the antenna assembly 20 can provide four feeding points, the two 2GFEMs 13 and the two 5GFEMs 14 can be connected to the antenna assembly 20 through the feeder lines 11, respectively. Figure 1 Compared with the embodiment shown in the figure, in this embodiment, no duplexer needs to be added, thereby reducing the cost of the electronic device 1.

[0063] In other embodiments, the antenna assembly 20 may include two antennas 22, and the antenna assembly 20 has two feeding points. Alternatively, the antenna assembly 20 may include three antennas 22, and the antenna assembly 20 has three feeding points. Alternatively, the antenna assembly 20 may include five antennas 22, and the antenna assembly 20 has five feeding points. Of course, the antenna assembly 20 may also include a greater number of antennas 22.

[0064] The following description mainly takes the example that the antenna assembly 20 includes four antennas 22 .

[0065] Regarding the number of working frequency bands of the antenna assembly 20, in this embodiment, the antenna assembly 20 may have two working frequency bands. That is, among the four antennas 22, the working frequency bands of the first antenna 22 are the same, the working frequency bands of the second antenna 22 are the same, and the working frequency bands of the first antenna 22 and the second antenna 22 are different. Thus, the antenna assembly 20 can realize the function of dual-frequency quad-feed. In other embodiments, the antenna assembly 20 may have three working frequency bands, four working frequency bands, or more working frequency bands.

[0066] The two operating frequency bands may be two operating frequency bands among the operating frequency band of the 2G antenna, the operating frequency band of the 3G antenna, the operating frequency band of the 4G antenna, and the operating frequency band of the 5G antenna.

[0067] Exemplarily, in a possible implementation, the operating frequency band of the first antenna 221 may be the same as the operating frequency band of the second antenna 222, the operating frequency band of the third antenna 223 may be the same as the operating frequency band of the fourth antenna 224, and the operating frequency bands of the third antenna 223 and the fourth antenna 224 are both lower than the operating frequency bands of the first antenna 221 and the second antenna 222. In one example, the first antenna 221 and the second antenna 222 are both 5G antennas, and the third antenna 223 and the fourth antenna 224 are both 2G antennas. In another example, the first antenna 221 and the second antenna 222 are both 2G antennas, and the third antenna 223 and the fourth antenna 224 are both 5G antennas.

[0068] In another possible implementation, the first antenna 221, the second antenna 222, and the third antenna 223 have the same operating frequency band, and the fourth antenna 224 has a different operating frequency band from the first antenna 221. Exemplarily, the first antenna 221, the second antenna 222, and the third antenna 223 are all 5G antennas, and the fourth antenna 224 is a 2G antenna; or, the first antenna 221, the second antenna 222, and the third antenna 223 are all 2G antennas, and the fourth antenna 224 is a 5G antenna.

[0069] like Figure 6As shown, the first antenna 221 and the second antenna 222 can both be plate-shaped structures. The first antenna 221 and the second antenna 222 can be fixed on the third support plate 213 at intervals. This can increase the distance between the first antenna 221 and the second antenna 222, thereby improving antenna isolation.

[0070] Based on this, in a possible implementation, the polarization directions of the first antenna 221 and the second antenna 222 are different. Exemplarily, the first antenna 221 may be a vertically polarized antenna, and the second antenna 222 may be a horizontally polarized antenna. In this way, the antenna assembly 20 can realize the dual-polarization function, that is, the antenna assembly 20 of the embodiment of the present application can realize the dual-frequency four-feed dual-polarization function, thereby improving the throughput of the antenna assembly 20. It can be understood that in this case, the structures of the first antenna 221 and the second antenna 222 are different.

[0071] In another possible implementation manner, the polarization directions of the first antenna 221 and the second antenna 222 are the same. In this case, the structures of the first antenna 221 and the second antenna 222 may be the same.

[0072] like Figure 2 As shown, in this embodiment, the third antenna 223 may be an "L"-shaped structure, for example, the third antenna 223 may include a first substrate 2231 and a second substrate 2232 that are connected and have an angle. The first substrate 2231 of the third antenna 223 is fixed on the first support plate 211, and the second substrate 2232 of the third antenna 223 is fixed on the second support plate 212. In this way, the third antenna 223 is fixedly connected to the two support plates of the insulating support body 21, thereby making the connection strength between the third antenna 223 and the insulating support body 21 higher.

[0073] Furthermore, in one example, Figure 3 As shown, the first substrate 2231 of the third antenna 223 is fixed to the surface a1 of the first support plate 211 away from the second support plate 212, and the second substrate 2232 of the third antenna 223 is fixed to the surface a2 of the second support plate 212 away from the third support plate 213. Here, the inner side and the outer side of the insulating support body 21 can be defined, and a receiving space 214 can be formed between the second support plate 212 and the third support plate 213 of the insulating support body 21. The receiving space 214 can be the inner side of the insulating support body 21, and the side opposite to the inner side is the outer side. In other words, the third antenna 223 is fixed to the outer side of the insulating support body 21.

[0074] In another example, Figure 4As shown, a through hole is provided on the first support plate 211 near the second support plate 212, and the first substrate 2231 of the third antenna 223 can be fixed to the surface a1 of the first support plate 211 away from the second support plate 212, and a portion of the second substrate 2232 of the third antenna 223 can be located in the through hole, and another portion extends out of the through hole. And the second substrate 2232 is fixed to the surface a3 of the second support plate 212 facing the third support plate 213. In this way, a portion of the third antenna 223 is fixed to the second support plate 212 in an embedded manner, thereby further improving the connection strength between the third antenna 223 and the second support plate 212, that is, improving the connection strength between the third antenna 223 and the insulating support body 21.

[0075] The fourth antenna 224 may have the same structure as the third antenna 223. Figure 2 As shown, the fourth antenna 224 may also be an "L"-shaped structure. For example, the fourth antenna 224 may include a first substrate 2231 and a second substrate 2232 that are connected and have an angle. The first substrate 2231 of the fourth antenna 224 is fixed on the first support plate 211, and the second substrate 2232 of the fourth antenna 224 is fixed on the second support plate 212. The fourth antenna 224 is also fixedly connected to the two support plates of the insulating support 21, thereby making the connection strength between the fourth antenna 224 and the insulating support 21 higher.

[0076] Furthermore, if Figure 3 As shown, the first substrate 2231 of the fourth antenna 224 is fixed to the surface a1 of the first support plate 211 away from the second support plate 212, and the second substrate 2232 of the fourth antenna 224 is fixed to the surface a2 of the second support plate 212 away from the third support plate 213. In other words, the fourth antenna 224 is fixed to the outer side of the insulating support body 21. Or, as Figure 4 As shown, the first substrate 2231 of the fourth antenna 224 can be fixed to the surface a1 of the first support plate 211 away from the second support plate 212, and a portion of the second substrate 2232 of the fourth antenna 224 can be located in the through hole, and another portion extends out of the through hole. And the second substrate 2232 of the fourth antenna 224 is fixed to the surface a3 of the second support plate 212 facing the third support plate 213. In this way, a portion of the fourth antenna 224 is fixed to the second support plate 212 in an embedded manner, thereby further improving the connection strength between the fourth antenna 224 and the second support plate 212, that is, improving the connection strength between the fourth antenna 224 and the insulating support body 21.

[0077] Moreover, if Figure 2As shown, the end of the second substrate 2232 of the third antenna 223 away from the first substrate 2231 is flush with the end of the second support plate 212 away from the first support plate 211. Also, the end of the second substrate 2232 of the fourth antenna 224 away from the first substrate 2231 is flush with the end of the second support plate 212 away from the first support plate 211.

[0078] It can be understood that, in this embodiment, Figure 2 As shown, the third antenna 223 and the fourth antenna 224 may both be “L”-shaped structures. In other embodiments, the third antenna 223 and the fourth antenna 224 may also be plate-shaped structures.

[0079] like Figure 2 As shown, the antenna assembly 20 may further include a decoupling portion 23. The decoupling portion 23 is fixed on the insulating support 21 and is located between the third antenna 223 and the fourth antenna 224. For example, in this embodiment, the decoupling portion 23 is fixed on the second support plate 212. In other embodiments, the decoupling portion 23 may be fixed on the first support plate 211. In this way, the decoupling portion 23 can reduce the coupling between the signal of the third antenna 223 and the signal of the fourth antenna 224, thereby further improving the antenna isolation.

[0080] The antenna assembly 20 of the embodiment of the present application can be manufactured in the following two ways:

[0081] First, each antenna 22 can be made by stamping, machining, etc. Each antenna 22 is placed in a mold, and injection molding is performed in the mold to form an insulating support 21, and an antenna assembly 20 is produced. The insulating support 21 can be an insulating material such as plastic, and each antenna 22 is connected to the insulating support 21 after the injection molding is completed. Since the third antenna 223 and the fourth antenna 224 are both fixed to the outside of the insulating support 21, when the third antenna 223 and the fourth antenna 224 are placed in the mold before injection molding, the third antenna 223 and the fourth antenna 224 can be placed in contact with the inner wall of the mold, thereby facilitating the fixing of the third antenna 223 and the fourth antenna 224 in the mold.

[0082] Second, the insulating support 21 can be first manufactured by injection molding. The region on the insulating support 21 where the antenna 22 is provided is metallized to form each antenna 22, thereby manufacturing the antenna assembly 20. When the third antenna 223 and the fourth antenna 224 are both fixed to the outside of the insulating support 21, it is convenient to manufacture the third antenna 223 and the fourth antenna 224 by metallization.

[0083] In addition, since in this embodiment, each antenna 22 and the insulating support 21 are made of different materials and different processes, when making each antenna 22, the antenna 22 can be made into an antenna 22 with certain decoupling function and filtering function. Therefore, on the one hand, the integration of the antenna assembly 20 is improved, and on the other hand, Figure 7 As shown, can be cancelled Figure 1 The filter 12 in the illustrated embodiment can further reduce the cost of the electronic device 1. On the other hand, the coupling between the signal of the first antenna 221 and the signal of the second antenna 222 can be reduced, as well as the coupling between the signal of the first antenna 221 and the signal of the fourth antenna 224 and the coupling between the signal of the second antenna 222 and the signal of the fourth antenna 224 can be reduced, thereby improving the antenna isolation.

[0084] The electronic device 1 generally includes a circuit board 30, such as Figure 8 and Fig. 9 As shown, the antenna assembly 20 can be fixed on the circuit board 30. For example, the second support plate 212 and the third support plate 213 can be bonded to the circuit board 30, thereby achieving a fixed connection between the antenna assembly 20 and the circuit board 30. In addition, the third antenna 223 and the fourth antenna 224 can also be welded to the circuit board 30, thereby achieving a fixed connection between the antenna assembly 20 and the circuit board 30.

[0085] In other embodiments of the present application, Figure 2 The difference between the embodiments shown is that the structure of the insulating support 21, the structures of the third antenna 223 and the fourth antenna 224 are different, and the embodiment is Figure 2 The decoupling portion 23 is omitted from the illustrated embodiment.

[0086] In this embodiment, the insulating support body 21 includes a first support plate 211 and a second support plate 212 fixed on the first support plate 211 , and an angle is formed between the second support plate 212 and the first support plate 211 .

[0087] In one example, if Fig.10 As shown, the end of the second support plate 212 is fixedly connected to the end of the first support plate 211, thereby, the insulating support body 21 can form an "L"-shaped structure.

[0088] In another example, Fig.11 As shown, the second support plate 212 is fixed to the middle of the first support plate 211, so that the insulating support body 21 can form a "T"-shaped structure. Compared with the flat insulating support body 21, the insulating support body 21 of this embodiment has higher strength.

[0089] like Fig.10As shown, a portion of the antenna 22 is fixed on the first support plate 211, and another portion of the antenna 22 is fixed on the second support plate 212. Exemplarily, the first antenna 221, the second antenna 222, the third antenna 223 and the fourth antenna 224 can all be plate-shaped structures. Fig.10 As shown, in this embodiment, the first antenna 221 and the second antenna 222 are fixed on the first support plate 211, and the third antenna 223 and the fourth antenna 224 are fixed on the second support plate 212. In other embodiments, the first antenna 221 and the third antenna 223 can be fixed on the first support plate 211, and the second antenna 222 and the fourth antenna 224 can be fixed on the second support plate 212. In this way, the number of antennas 22 fixed on the first support plate 211 and the second support plate 212 is relatively small, thereby increasing the distance between the antennas 22 fixed on the same support plate, thereby reducing the signal interference between the antennas 22 fixed on the same support plate, thereby improving the antenna isolation.

[0090] The electronic device 1 generally includes a circuit board 30, such as Fig.12 and Fig.13 As shown, the antenna assembly 20 can be fixed on the circuit board 30. In one example, as shown in FIG. Fig.12 As shown, the second support plate 212 of the insulating support body 21 is fixed on the circuit board 30, and there is a gap between the first support plate 211 and the circuit board 30. In another example, as Fig.13 As shown, the first support plate 211 and the second support plate 212 are both in contact with the circuit board 30 and fixed on the circuit board 30 .

[0091] In other embodiments of the present application, Fig.10 The difference of the embodiment shown is that in this embodiment Fig.10 A decoupling unit 23 is added on the basis of the embodiment shown. Fig.14 As shown, the second support plate 212 includes a first surface 2121. The third antenna 223, the decoupling portion 23 and the fourth antenna 224 are fixed to the first surface 2121 at intervals. In this way, there is a distance between the third antenna 223 and the decoupling portion 23, and there is a distance between the decoupling portion 23 and the fourth antenna 224, thereby further improving the decoupling effect of the decoupling portion 23 on the third antenna 223 and the fourth antenna 224.
