[0034] For a better understanding of the present application, the antenna assembly 10, housing 20, and mobile terminal according to embodiments of the present application will be described in detail below with reference to FIGS.

[0035] 1 and 2, FIG. 1 is a schematic structural diagram of an antenna assembly 10 according to an embodiment of the present application, and FIG. 2 is a schematic structural diagram of the antenna assembly 10 according to an embodiment of the present application from another perspective.

[0036] 1 and 2, an embodiment of a first aspect of the present application provides an antenna assembly 10 including a substrate 100, an antenna module 200, an integrated circuit 300, and a connection portion 400. The substrate 100 includes a first sub-portion 110 and a second sub-portion 120 in a first direction Y, the antenna module 200 is provided in the first sub-portion 110 and includes two or more antenna units 210 distributed at intervals in the first sub-portion 110, the integrated circuit 300 is provided in the second sub-portion 120, and the connection portion 400 is provided on the substrate 100 and electrically connects the antenna unit 210 and the integrated circuit 300.

[0037] The antenna assembly 10 according to the present application includes a substrate 100, an antenna module 200, an integrated circuit 300, and a connection portion 400. The substrate 100 provides mounting positions for the antenna module 200, the integrated circuit 300, and the connection portion 400. A plurality of antenna units 210 are spaced apart in the first sub-portion 110, and the integrated circuit 300 is mounted in the second sub-portion 120, thereby improving positional interference between the antenna units 210 and the integrated circuits 300. The antenna units 210 and the integrated circuits 300 at different positions on the substrate 100 are electrically connected to each other by the connection portion 400, thereby enabling the integrated circuit 300 to transmit control signals to the antenna units 210. In the antenna assembly 10 of the present application, the antenna module 200, the integrated circuit 300, and the connecting portion 400 are all installed on the substrate 100. After the installation on the substrate 100, the substrate 100 having the antenna module 200, the integrated circuit 300, and the connecting portion 400 is uniformly installed at the target position. For example, when the antenna assembly 10 is used in a mobile terminal, the substrate 100 having the antenna module 200, the integrated circuit 300, and the connecting portion 400 can be easily and uniformly installed in the housing 20 of the mobile terminal, thereby simplifying the installation process of the antenna assembly 10 and reducing related costs.

[0038] Optionally, the first sub-unit 110 and the second sub-unit 120 may be distributed at intervals along the first direction Y. Optionally, the integrated circuit 300 may include a radio frequency integrated circuit and a battery management integrated circuit, and the radio frequency integrated circuit is connected to the antenna unit 210 to transmit a radio frequency signal to the antenna unit 210. Optionally, the integrated circuit 300 may include only the radio frequency integrated circuit.

[0039] In some optional embodiments, referring also to Figures 1-4, the substrate 100 further includes a folding portion 130 connecting the first sub-portion 110 and the second sub-portion 120, the first sub-portion 110, the second sub-portion 120 and the folding portion 130 being integrally formed, one end of the connection portion 400 being connected to the antenna unit 210, and the other end extending to the integrated circuit 300 via the folding portion 130, electrically connecting the antenna unit 210 and the integrated circuit 300.

[0040] In these alternative embodiments, the substrate 100 is integrally formed in a substantially U-shape and includes a first sub-section 110, a second sub-section 120, and a folding section 130. This allows the antenna assembly 10 to break through a metal shield through the substrate 100. For example, the antenna assembly 10 is mounted on a frame of a mobile terminal, and the substrate 100 covers the inner and outer surfaces of the frame to break through the metal shield. This also ensures a closer distance between the antenna unit 210 and the integrated circuit 300, thereby minimizing intermediate loss and further improving the performance of the antenna assembly 10 and the quality of wireless communication. The substrate 100 may be mounted in various ways, such as a rigid substrate 100, glass, or a steel plate. Alternatively, the material of the substrate 100 may include flexible materials such as polyimide, liquid crystal polymer, polyethylene terephthalate (PET), cyclo olefin polymer (COP), etc., which makes it easy for the substrate 100 to change shape depending on the installation position, further simplifying the installation difficulty of the antenna assembly 10.

[0041] Optionally, the antenna assembly 10 further includes a connector 600, which is electrically connected to the integrated circuit 300, and both the connector 600 and the integrated circuit 300 are provided in the second sub-portion 120. This reduces the distance between the connector 600 and the integrated circuit 300, facilitating connection between the connector 600 and the integrated circuit 300. The integrated circuit 300 may be electrically connected to the outside via the connector 600; for example, the integrated circuit 300 may be electrically connected to a motherboard of a mobile terminal or the like via the connector 600.

[0042] When the material of the substrate 100 includes a flexible material, the integrated circuit 300, the connection portion 400, the antenna unit 210, and the connector 600 can be placed on the substrate 100 while the substrate 100 is in a planar state, facilitating the arrangement of the integrated circuit 300, the connection portion 400, the antenna unit 210, and the connector 600. Thereafter, the substrate 100 is folded to form the first sub-portion 110, the second sub-portion 120, and the folded portion 130 that connects the first sub-portion 110 and the second sub-portion 120 by folding them, thereby facilitating the placement of the substrate 100 at the target position through the U-shaped opening.

[0043] Optionally, the widths and lengths of the first sub-portion 110 and the second sub-portion 120 may be the same or different. To simplify the shape of the substrate 100, the widths and lengths of the first sub-portion 110 and the second sub-portion 120 may be the same. The widths of the first sub-portion 110 and the second sub-portion 120 may be the extension sizes of the first sub-portion 110 and the second sub-portion 120 in the third direction Z, and the lengths of the first sub-portion 110 and the second sub-portion 120 may be the extension sizes of the first sub-portion 110 and the second sub-portion 120 in the second direction X. Optionally, the length of the folding portion 130 may be the same as or different from the lengths of the first sub-portion 110 and the second sub-portion 120. For example, the length of the folding portion 130 may be smaller than the lengths of the first sub-portion 110 and the second sub-portion 120 depending on the limitations of the target position.

[0044] The bending portion 130 may be installed in various ways. As shown in Figures 1 and 2, the bending portion 130 may be connected to one side of the first sub-part 110 in the third direction Z. Alternatively, as shown in Figures 3 and 4, the bending portion 130 may be connected to one side of the first sub-part 110 in the second direction X. Optionally, the extension size of the first sub-part 110 in the second direction X is larger than the extension size in the third direction Z.

[0045] In another alternative embodiment, as shown in Figures 5 and 6, the first sub-section 110 and the second sub-section 120 are provided separately, and the connection section 400 includes a first sub-segment 410 provided in the first sub-section 110 and electrically connected to the antenna unit 210, and a second sub-segment 420 provided in the second sub-section 120 and electrically connected to the integrated circuit 300, and the first sub-segment 410 and the second sub-segment 420 are binding-connected, or the first sub-segment 410 and the second sub-segment 420 are electrically connected to each other via a connector.

[0046] In these alternative embodiments, the first sub-section 110 and the second sub-section 120 are provided separately. In this case, the antenna unit 210 and the integrated circuit 300 can be provided in two different parts of the substrate 100, respectively, with the antenna unit 210 provided on the substrate 100 and the integrated circuit 300 provided on the substrate 100, so that they do not interfere with each other. The connecting section 400 is divided into a first sub-segment 410 and a second sub-segment 420, which can be connected by binding, increasing the freedom of material selection, reducing the size and cost of the antenna module 200, and improving the performance reliability of the antenna module 200. Alternatively, the first sub-segment 410 and the second sub-segment 420 can be connected to each other by a plug, which facilitates maintenance and replacement.

[0047] 5 and 6, the bent portion 130 may be integral with the first sub-portion 110, and the bent portion 130 and the second sub-portion 120 may be separate and connected to each other. In other embodiments, the bent portion 130 may be integral with the second sub-portion 120, and the bent portion 130 and the first sub-portion 110 may be separate and connected to each other.

[0048] In some optional embodiments, as shown in FIG. 7, the antenna assembly 10 further includes a conductive isolation portion 140 provided in the first sub-portion 110 and positioned between two adjacent antenna units 210.

[0049] In these alternative embodiments, a conductive isolation portion 140 is provided between two adjacent antenna units 210 to improve the problem of signal mutual interference between the two adjacent antenna units 210.

[0050] Alternatively, the conductive isolation portion 140 may be provided on the surface of the first sub-portion 110 and / or the conductive isolation portion 140 may be provided within the first sub-portion 110. The conductive isolation portion 140 may be located between two adjacent antenna units 210.

[0051] Optionally, the conductive isolation portion 140 includes a first conductive isolation portion 141 provided on the surface of the first sub-portion 110 and a second conductive isolation portion 142 provided within the first sub-portion 110, and the first conductive isolation portion 141 and the second conductive isolation portion 142 are connected to each other. In the first direction Y, by providing the first conductive isolation portion 141 located on the surface of the first sub-portion 110 and the second conductive isolation portion 142 located within the first sub-portion 110, the degree of isolation between adjacent antenna units 210 can be increased, and the problem of antenna mutual coupling between two adjacent antenna units 210 can be better alleviated, thereby improving the performance of wireless communication.

[0052] Optionally, a first conductive isolation portion 141 is provided on both surfaces of the first sub-section 110 facing toward or away from the second sub-section 120, i.e., the first conductive isolation portion 141 is provided on two opposite surfaces of the first sub-section 110, and the second conductive isolation portion 142 is connected to the first conductive isolation portion 141 located on the two opposite surfaces of the first sub-section 110, thereby further increasing the isolation between adjacent antenna units 210 and better alleviating the problem of antenna mutual coupling between two adjacent antenna units 210, thereby improving the performance of wireless communication.

[0053] Optionally, when the antenna assembly 10 is installed in the housing of a mobile terminal, the first conductive isolation portions 141 of the first sub-portion 110 facing the surface of the second sub-portion 120 are connected to the frame of the housing in contact with each other, which can better alleviate the problem of antenna mutual coupling between two adjacent antenna units 210 and further improve wireless communication performance. In any of the above embodiments, the installation manner of the antenna module 200 can be various, and the antenna module 200 can be used to transmit and receive wireless signals of various frequency bands, for example, the wireless module can be used to transmit and receive millimeter wave wireless signals.

[0054] 8 to 11, an embodiment of a second aspect of the present application further provides a housing 20 of a mobile terminal, where the mobile terminal includes an antenna assembly 10, and the antenna assembly 10 includes a plurality of antenna units 210. Optionally, the antenna assembly 10 may be the antenna assembly 10 according to any one of the above embodiments. The antenna assembly 10 may also be the antenna assembly 10 according to another embodiment. The present application will be described taking as an example the antenna assembly 10 being the antenna assembly 10 according to any one of the above first embodiments.

[0055] The installation manner of the housing 20 may vary. In some embodiments, as shown in Figures 8-10, Figure 8 is a structural schematic diagram of a frame body 500, Figure 9 is a structural schematic diagram of a sub-segment portion 501, and Figures 10 and 11 are structural schematic diagrams of the sub-segment portion 501 from different perspectives when the antenna assembly 10 is installed in the sub-segment portion 501. The housing 20 includes a frame body 500 that surrounds and defines a hollow space 502, and the frame body 500 includes a sub-segment portion 501, where the sub-segment portion 501 includes an inner surface 510 facing the hollow space 502 and an outer surface 520 facing away from the hollow space 502, and at least one of the inner surface 510 and the outer surface 520 is recessed to form a first groove 530 that extends along the extension direction of the sub-segment portion 501 and is used to accommodate multiple antenna units 210.

[0056] In these alternative embodiments, some sub-segment portions 501 of the frame body 500 are recessed to form first grooves 530, which can accommodate multiple antenna units 210. For example, when the antenna assembly 10 is the above-described antenna assembly 10, the first groove 530 can accommodate the base material 100, on which multiple antenna units 210 are disposed at intervals. By accommodating multiple antenna units 210 in the same first groove 530, the installation process for the multiple antenna units 210 can be improved, which can improve the assembly efficiency of the antenna assembly 10 and reduce costs.

[0057] Optionally, the frame 500 may be provided with a plurality of first grooves 530, each for accommodating a plurality of antenna units. The plurality of first grooves 530 may be provided at different positions on the frame 500, so that the plurality of antenna assemblies 10 are not simultaneously covered when the mobile terminal is in a plurality of orientations, such as a landscape screen orientation and a portrait screen orientation. This may reduce blind areas for wireless signals and achieve better communication quality. The extension direction of the sub-segment 501 may be such that it surrounds the hollow space 502 of the sub-segment 501. For example, the frame 500 includes a plurality of sub-segments 501, which are connected head to tail to form the hollow space 502. The plurality of sub-segments 501 include two first sub-segments spaced apart along the first direction Y and two second sub-segments spaced apart along the second direction X, where the two first sub-segments and the two second sub-segments alternately surround one another to form a hollow space. When the first groove 530 is provided in the first sub-segment, the first sub-segment extends in the second direction X, and the first groove 530 extends along the second direction X, and the plurality of antenna units 210 can be spaced apart in the first groove 530 along the second direction X. When the first groove 530 is provided in the second sub-segment, the second sub-segment extends in the first direction Y, and the first groove 530 extends along the first direction Y, and the plurality of antenna units 210 can be spaced apart in the first groove 530 along the first direction Y.

[0058] Optionally, the frame may be an intermediate frame of the mobile terminal.

[0059] 12-14, in some optional embodiments, Figures 12 and 13 are structural schematic diagrams of the sub-segment portion 501 at different viewing angles, and Figure 14 is a structural schematic diagram of the antenna assembly 10 at different viewing angles when the antenna assembly 10 is installed on the sub-segment portion 501 shown in Figures 12 and 13. The first bottom wall surface 531 of the first groove 530 is recessed to form two or more cavities 533, and each cavity 533 is provided corresponding to each antenna unit 210.

[0060] In these optional embodiments, when a cavity 533 is provided on the first bottom wall surface 531 of the first groove 530 and the antenna unit 210 is provided in the first groove 530, the positions of the first groove 530 and the cavity 533 correspond, that is, the orthogonal projection of the antenna unit 210 on the first bottom wall surface 531 at least partially overlaps with the cavity 533, so that the distance between the antenna unit 210 and the surface of the cavity 533 can be increased, and the distance between the first bottom wall surface 531 and the antenna unit 210 is too close, which affects the antenna performance, thereby achieving better antenna performance and better wireless communication quality.

[0061] Optionally, the cavities 533 and the antenna units 210 are provided in one-to-one correspondence, and each antenna unit 210 has a corresponding cavity 533 .

[0062] Optionally, the size of the cavity 533 is smaller than the size of the first groove 530, for example, the projection of the cavity 533 along the first direction Y of the sub-segment portion 501 is located within the projection of the first groove 530 along the thickness direction Z of the sub-segment portion 501, so that at least a part of the first wall surface protrudes from the cavity 533, for example, the first bottom wall surface 531 on the circumferential side of the cavity 533 protrudes from the cavity 533, and the antenna unit 210 or the substrate 100 for installing the antenna unit 210 is overlapped and connected to the circumferential side of the cavity 533, thereby ensuring the distance between the antenna unit 210 and the surface of the cavity 533.

[0063] Alternatively, in order to provide the cavity 533 and the first groove 530 in the sub-segment portion 501, a portion of the sub-segment portion 501 may be thickened as shown in FIG. 13, for example, by partially thickening the portion of the sub-segment portion 501 for providing the first groove 530 and the cavity 533, thereby improving the structural strength of the sub-segment portion 501.

[0064] In some alternative embodiments, the sub-segment portion 501 includes a channel 540 extending through the inner surface 510 and the outer surface 520, the channel 540 and the first groove 530 communicating with each other.

[0065] In these optional embodiments, the sub-segment portion 501 further includes a channel 540, and the channel 540 is connected to the first groove 530, so that the connection portion 400 can be connected to the antenna unit 210 located in the first groove 530 through the channel 540, facilitating mutual electrical connection between the antenna unit 210 and the integrated circuit 300.

[0066] The location of the channel 540 may vary. For example, as shown in Figures 8-14, the sub-segment portion 501 may further include a side surface 550 connecting the inner surface 510 and the outer surface 520, and the channel 540 may be formed with a recessed side surface 550. When the substrate 100 includes the first sub-portion 110, the second sub-portion 120, and the folded portion 130, the folded portion 130 may be positioned within the channel 540, thereby alleviating the problem of the folded portion 130 protruding too high from the side surface 550.

[0067] 15-18, the first groove 530 further includes a first side wall 532 connected to the periphery of the first bottom wall 531, and the channel 540 communicates with the first side wall 532. Alternatively, as shown in FIGS. 19-21, the channel 540 communicates with the first bottom wall 531. When the substrate 100 includes the first sub-portion 110 and the second sub-portion 120 that are provided separately, the first sub-portion 110 and the second sub-portion 120 may be provided separately on the inner surface 510 and the outer surface 520, and the connection portion 400 is connected to the antenna unit 210 and the integrated circuit 300 via the channel 540 that communicates with the first side wall 532 or the first bottom wall 531.

[0068] The first groove 530 may be provided on the inner surface 510 or the outer surface 520 .

[0069] In some alternative embodiments, the first groove 530 is located on the outer surface 520, and the housing 20 further includes a second groove 560 recessed into the inner surface 510, the second groove 560 being used to accommodate the integrated circuit 300 of the antenna assembly 10.

[0070] In these alternative embodiments, the first groove 530 is located on the outer surface 520, thereby exposing the antenna unit 210 disposed within the first groove 530, and improving the effect of the frame 500 on the signal transmission of the antenna unit 210. The inner surface 510 is further provided with a second groove 560, which accommodates the integrated circuit 300 and provides positioning and positional constraints for the second sub-part 120 for installing the integrated circuit 300.

[0071] Optionally, the housing 20 may further include a decorative cover 700, which may be provided to cover the first groove 530. The decorative cover 700 can provide aesthetic benefits, wear resistance, waterproofing, dust resistance, drop resistance, and the like.

[0072] Optionally, the material of the frame body 500 may include a metal material to ensure sufficient structural strength of the frame body 500. Optionally, the material of the decorative cover 700 may include an insulating material to reduce the influence on signal transmission of the antenna unit 210 in the first groove 530 when the decorative cover 700 is provided to cover the first groove 530.

[0073] Optionally, the shapes of the decorative cover 700 and the first groove 530 are matched, the area and shape of the decorative cover 700 and the first bottom wall surface 531 are the same, and the decorative cover 700 and the first side wall surface 532 are in contact with and connected to each other. Optionally, if the first groove 530 is provided on the outer surface 520, the decorative cover 700 and the outer surface 520 are flush with each other to ensure the flatness of the outer surface 520 of the frame body 500. If the first groove 530 is provided on the inner surface 510, the decorative cover 700 may be flush with the inner surface 510.

[0074] As described above, when the channel 540 communicates with the first side wall surface 532 or the first bottom wall surface 531, the shape of the container 700 does not need to be irregular, which is advantageous in terms of aesthetic design and aesthetics for many consumers.

[0075] Optionally, the decorative cover 700 may be provided to cover the second groove 560, and the shape of the decorative cover 700 may match that of the second groove 560. The second groove 560 includes a second bottom wall surface and a second side wall surface connected to the periphery of the second bottom wall surface. The area and shape of the decorative cover 700 and the second bottom wall surface are the same, and the decorative cover 700 and the second side wall surface are in contact with and connected to each other. Optionally, if the second groove 560 is provided on the inner surface 510, the decorative cover 700 and the inner surface 510 are flush with each other, ensuring the flatness of the inner surface 510 of the frame body 500. If the second groove 560 is provided on the outer surface 520, the decorative cover 700 may be flush with the outer surface 520.

[0076] In any of the above embodiments, if the antenna assembly 10 includes a conductive isolation portion 140, the projection of the conductive isolation portion 140 along the first direction Y and the projection of the cavity 533 along the first direction Y are offset from each other. For example, the projection of the conductive isolation portion 140 along the first direction Y is located between the projections of two adjacent cavities 533 along the first direction Y. Optionally, if the conductive isolation portion 140 is located on the side of the first subsection 110 facing the second subsection 120, the conductive isolation portion 140 located on the side of the first subsection 110 facing the second subsection 120 is electrically connected to the sub-segment portion 501, thereby further improving the isolation between two adjacent antenna units 210 and achieving better antenna performance and better wireless communication quality.

[0077] As shown in Figures 1 to 20, a third aspect of the present application further provides a mobile terminal including an antenna assembly 10 of any one of the first aspect of the application and a housing 20 of any one of the second aspect of the application, and the first sub-portion 110 of the substrate 100 is located in the first groove 530.

[0078] In the embodiments of the present application, mobile terminals include, but are not limited to, devices with display capabilities such as mobile phones, personal digital assistants (abbreviated as PDAs), tablet computers, e-books, televisions, door access devices, smart landlines, and consoles.

[0079] In the mobile terminal of this embodiment, some sub-segment portions 501 of the frame body 500 are recessed to form first grooves 530, which can accommodate the first sub-portions 110 of the base material 100, and multiple antenna units 210 are provided in the first sub-portion 110 at intervals. By accommodating multiple antenna units 210 in the same first groove 530, the installation process for the multiple antenna units 210 can be improved, and the assembly efficiency of the antenna assembly 10 can be enhanced.

[0080] In some alternative embodiments, the first groove 530 is located on the outer surface 520 and the second sub-portion 120 is located on the inner surface 510 .

[0081] In these optional embodiments, the first groove 530 is located on the outer surface 520, and the first sub-portion 110 provided in the first groove 530 is located on the outer surface 520, so that the plurality of antenna units 210 located on the first sub-portion 110 are located on the outer surface 520, which improves shielding of the antenna units 210 by the housing 20, exposes the antenna units 210, and improves the performance of the antenna assembly 10. The second sub-portion 120 is located on the inner surface 510, so that the integrated circuit 300 located on the second sub-portion 120 is located on the inner surface 510, and the frame 500 can protect the integrated circuit 300.

[0082] In some optional embodiments, the frame 500 further includes a second groove 560 formed by recessing the inner surface 510, and the second sub-part 120 is positioned in the second groove 560. This allows the second groove 560 to provide positioning and restriction for the second sub-part 120.

[0083] Optionally, the first groove 530 has a first bottom wall surface 531, and the antenna unit 210 is provided on the side of the first sub-part 110 away from the first bottom wall surface 531 to improve shielding of the first sub-part 110 from the antenna unit 210.

[0084] Optionally, the second groove 560 has a second bottom wall surface, and the integrated circuit 300 is provided on the side away from the second bottom wall surface of the second sub-part 120 so that the integrated circuit 300 is exposed, making it easy for the connection part 400 to connect the antenna unit 210 and the integrated circuit 300.

[0085] Optionally, as described above, the sub-segment portion 501 includes a channel 540 formed through the inner surface 510 and the outer surface 520, the channel 540 and the first groove 530 communicate with each other, and the connection portion 400 electrically connects the antenna unit 210 and the integrated circuit 300 via the channel 540. By providing the channel 540 in the frame body 500, the connection portion 400 electrically connects the antenna unit 210 and the integrated circuit 300 via the channel 540, and the extension length of the connection portion 400 can be shortened.

[0086] Optionally, the sub-segment 501 may further include a first side surface 551 and a second side surface 552 that are opposed to each other and connect the inner surface 510 and the outer surface 520. The channel 540 is formed by recessing the first side surface 551, i.e., the channel 540 is formed by reducing the size of a portion of the sub-segment 501. When the base material 100 is U-shaped and includes a first sub-portion 110, a second sub-portion 120, and a bent portion 130 connecting the first sub-portion 110 and the second sub-portion 120, the bent portion 130 may be positioned within the channel 540, thereby improving the flatness of the entire surface of the frame, which would otherwise be affected by the bent portion 130 protruding too much from the sub-segment 501.

[0087] For example, the top surface of the connecting portion 400 facing away from the second side surface 552 is flush with the first side surface 551, or the top surface of the connecting portion 400 facing away from the second side surface 552 is located on the side of the first side surface 551 facing the second side surface 552, so that the connecting portion 400 does not protrude from the first side surface 551 at any position other than the channel 540, improving the flatness of the surface of the entire frame.

[0088] Optionally, the antenna assembly 10 further includes a connector 600, which is electrically connected to the integrated circuit 300, and both the connector 600 and the integrated circuit 300 are provided in the second sub-portion 120. This reduces the distance between the connector 600 and the integrated circuit 300, facilitating connection between the connector 600 and the integrated circuit 300. The integrated circuit 300 may be electrically connected to the outside via the connector 600; for example, the integrated circuit 300 may be electrically connected to a motherboard of a mobile terminal or the like via the connector 600.

[0089] Alternatively, the antenna units 210 may be spaced apart along the extension direction of the sub-segment 501, and multiple antenna units 210 may be installed in the sub-segment 501. The extension direction of the sub-segment 501 is as described above, and will not be described here.

[0090] Optionally, the integrated circuits 300 and the connectors 600 are distributed at intervals along the extension direction of the sub-segment portion 501. The sub-segment portion 501 has a large size in its extension direction, which leaves more installation space for the integrated circuits 300 and the connectors 600.

[0091] Optionally, as described above, the housing 20 may further include a decorative cover 700, which may be provided to cover the first groove 530 and / or the second groove 560. The installation method of the decorative cover 700 has been described above, and therefore will not be described here.

[0092] In some optional embodiments, the first bottom wall surface 531 of the first groove 530 is recessed to form two or more cavities 533, and a projection along the thickness direction of the sub-segment 501 of each antenna unit 210 and a projection along the thickness direction of each cavity 533 are at least partially overlapped. The sub-segment 501 may have a plurality of thickness directions. For example, the sub-segment 501 may be the first sub-segment 410 and have a thickness direction along the first direction Y, or the sub-segment 501 may be the second sub-segment 420 and have a thickness direction along the second direction X. The thickness direction of the sub-segment 501 may also be considered as a direction in which the inner surface 510 and outer surface 520 of the sub-segment 501 itself are spaced apart.

[0093] In these optional embodiments, a cavity 533 is provided on the first bottom wall surface 531 of the first groove 530, and the projection of the cavity 533 and the antenna unit 210 at least partially overlaps, which can increase the distance between the antenna unit 210 and at least a portion of the first bottom wall surface 531, thereby improving the effect of the distance between the first bottom wall surface 531 and the antenna unit 210 being too close and affecting its operation, and improving the performance of the antenna assembly 10.

[0094] Optionally, the projection along the thickness direction of the sub-segment portion 501 of each antenna unit 210 is located within the projection along the thickness direction of the sub-segment portion 501 of each cavity 533, thereby better improving the performance of the antenna assembly 10.

[0095] Although the present application has been described above with reference to preferred embodiments, the present application is not limited to the above embodiments and various modifications and equivalent substitutions are possible within the scope of the present application. In particular, the technical features described in each embodiment can be arbitrarily combined as long as there is no structural contradiction. The present application is not limited to the specific embodiments disclosed in this specification and includes all technical solutions included within the scope of the claims.
