Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0066] To better understand this application, the following will be combined with... Figures 1 to 8 The antenna device 10 and the wireless mobile terminal according to the embodiments of this application will be described in detail.

[0067] Please refer to the following: Figures 1 to 2 , Figure 1 This is a schematic diagram of the structure of an antenna device 10 provided in an embodiment of this application; Figure 2 This is a partially enlarged structural schematic diagram of an antenna device 10 provided in an embodiment of this application.

[0068] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of this application provides an antenna device 10, which includes: a frame 100 enclosing a hollow space 120 and including a first segment 110 extending along a first direction Y; a bracket 210 connected to the first segment 110 on one side of a second direction X and located in the hollow space 120, wherein the extension dimension of the bracket 210 in the first direction Y is greater than its extension dimension in the second direction X; and an antenna assembly 300 including a first antenna module 301, wherein the materials of the bracket 210 and the first segment 110 both include conductive materials and are reused as at least a portion of the first antenna module 301.

[0069] In the antenna device 10 provided in this application, the antenna device 10 includes a frame 100, a bracket 210, and an antenna assembly 300. The frame 100 can enclose a hollow space 120 for accommodating the antenna assembly 300 and the bracket 210. The bracket 210 is connected to a first segment 110 of the frame 100 and is located in the hollow space 120 to provide a mounting position for the antenna assembly 300. The materials of the bracket 210 and the first segment 110 both include conductive materials and are reused as at least a part of the first antenna module 301. On the one hand, this can reduce the size of the hollow space 120 occupied by the first antenna module 301. On the other hand, the bracket 210 can also be used to provide support for other components, facilitating the arrangement of other components within the hollow space 120. Furthermore, in this embodiment, the bracket 210 is located on one side of the first segment 110 in the second direction X, and the extension dimension of the bracket 210 in the first direction Y is greater than its extension dimension in the second direction X. That is, the length direction of the bracket 210 is not perpendicular to the length direction of the first segment 110, and the bracket 210 is larger in the first direction Y. This allows the overall distance between the bracket 210 and the first segment 110 to be set closer, making the current distribution more concentrated near the first segment 110, and making the antenna radiation more oriented towards the top, thereby improving the wireless signal transmission and reception capability towards the top, and enhancing the wireless communication performance of the mobile terminal and the satellite. Therefore, this embodiment can improve the wireless communication performance of the wireless mobile terminal. Optionally, the angle between the length direction of the bracket 210 and the first direction Y can be greater than or equal to 0 degrees and less than 45 degrees. The length direction of the bracket 210 can be the line connecting the two ends of the bracket 210 with the largest extension dimension. This embodiment uses the length direction of the bracket 210 as the first direction Y for illustration. In other embodiments, the length direction of the bracket 210 may not be the first direction Y, as long as the extension dimension of the bracket 210 in the first direction Y is greater than its extension dimension in the second direction X.

[0070] Optionally, the antenna device 10 is used in a wireless mobile terminal, which may also include components such as a control motherboard, which may be located in the hollow space 120. Optionally, the frame 100 may be the middle frame of the wireless mobile terminal, and the frame 100 may surround the wireless mobile terminal.

[0071] Optionally, the frame 100 can be integrally molded, that is, an integrally molded closed ring frame 100 surrounds to form a hollow space 120.

[0072] In other embodiments, the frame 100 may further include multiple segments 110a, each segment 110a including a first segment 110, and the multiple segments 110a are arranged around the hollow space 120. Optionally, adjacent segments 110a are insulated from each other, for example, an insulating spacer layer is provided between adjacent segments 110a, to improve the impact of the frame 100 on the wireless signal transmission of the wireless mobile terminal, thereby improving antenna performance. This application embodiment uses the frame 100 including multiple segments 110a as an example for illustration.

[0073] There are several ways to set up the bracket 210. The bracket 210 can be in the shape of a plate, block, column, etc. Optionally, the bracket 210 can be in the shape of a plate to reduce the space occupied by the bracket 210.

[0074] Optionally, the antenna device 10 further includes a base plate 130, and a frame 100 is connected to the periphery of the base plate 130 and encloses the base plate 130 to form a hollow space 120. Optionally, the distance between the surface of the bracket 210 facing away from the base plate 130 and the base plate 130 is less than or equal to the distance between the surface of the frame 100 facing away from the base plate 130 and the base plate 130. That is, the surface of the bracket 210 facing away from the base plate 130 is positioned closer to the base plate 130 relative to the frame 100 in the third direction Z. The bracket 210 does not protrude from the frame 100 away from the base plate 130 in the third direction Z, which can reduce the overall volume of the antenna device 10.

[0075] Optionally, the baseboard 130 and the control motherboard of the wireless mobile terminal can be reused. Alternatively, the baseboard 130 and the control motherboard can be set up independently.

[0076] In some alternative embodiments, such as Figure 2 As shown, a grounding part 250 is connected to the bracket 210. The grounding part 250 abuts between the base plate 130 and the bracket 210, and the grounding part 250 is electrically connected to the bracket 210 and the base plate 130. The bracket 210 is electrically connected to the base plate 130 through the grounding part 250, and the bracket 210 and the base plate 130 can share the grounding potential.

[0077] In other cases, 250 may not be abutted against the base plate 130.

[0078] Or, such as Figure 3 As shown, the bracket 210 and the base plate 130 are spaced apart, that is, the bracket 210 is suspended relative to the base plate 130, which can increase the exposed area of ​​the base plate 130.

[0079] In some alternative embodiments, such as Figure 4 and Figure 5As shown, a reflective wall 220 is provided on the side of the bracket 210 facing the base plate 130. The reflective wall 220 can reflect the wireless signal on the first segment 110, thereby improving the performance of the first antenna module 301 (e.g., radiation gain) and enhancing the wireless performance of the mobile terminal.

[0080] There are several ways to set the relative position of the reflective wall 220 and the bracket 210. Optionally, the reflective wall 220 can be connected to the side of the bracket 210 that is closer to or farther away from the first segment 110. This can be achieved by reasonably adjusting the position of the reflective wall 220, for example... Figure 4 As shown, the reflective wall 220 is positioned on the side of the bracket 210 closer to the first segment 110 to reduce the distance between the reflective wall 220 and the first segment 110, or as... Figure 5 As shown, the reflector wall 220 is positioned on the side of the bracket 210 away from the first segment 110 to increase the distance between the reflector wall 220 and the first segment 110, thereby adjusting the reflection intensity of the reflector wall 220 on different frequency band wireless signal lines on the first segment 110.

[0081] Optionally, the extension dimension of the reflective wall 220 in the first direction Y is equal to the extension dimension of the support 210 in the first direction Y. This makes the reflective wall 220 large enough to enhance its function.

[0082] In other embodiments, the extension dimension of the reflective wall 220 in the first direction Y can also be equal to the dimension of the first segment 110 in the first direction Y, so that wireless signals at different locations on the first segment 110 can be reflected by the reflective wall 220.

[0083] Optionally, the extension dimension of the reflective wall 220 in the first direction Y can also be smaller than the extension dimension of the bracket 210 in the first direction Y.

[0084] Optionally, the reflector wall 220 and the base plate 130 are spaced apart, allowing more of the base plate 130 surface to be exposed. Alternatively, the reflector wall 220 abuts between the base plate 130 and the bracket 210 to improve the stability of the reflector wall 220's position. Optionally, the reflector wall 220 can be interconnected with the base plate 130, and the reflector wall 200 is used for grounding.

[0085] Optionally, the reflective wall 220 and the bracket 210 are integrally molded to improve the stability of their relative positions.

[0086] In some alternative embodiments, such as Figures 1 to 5 As shown, the antenna device 10 also includes a connecting part 230, one end of which is connected to the first segment 110 and the other end is connected to the bracket 210. The bracket 210 and the first segment 110 are spaced apart along the second direction X.

[0087] In these alternative embodiments, the bracket 210 is connected to the first segment 110 via the connecting portion 230. By reasonably adjusting the length of the connecting portion 230, the distance between the bracket 210 and the first segment 110 can be adjusted.

[0088] Optionally, the extension dimension of the connecting portion 230 in the second direction X is smaller than the extension dimension of the bracket 210 in the first direction Y. When the current on the bracket 210 flows through the connecting portion 230 to the first segment 110, the current flow distance between the bracket 210 and the first segment 110 can be extended, thereby improving the performance of the first antenna module 301 and enabling the first antenna module 301 to cover lower frequency bands.

[0089] Optionally, the connecting portion 230 extends along the second direction X. The bracket 210 and the first segment 110 are spaced apart along the second direction X, and the connecting portion 230 extends along the second direction X, which can appropriately reduce the extension distance of the connecting portion 230 so as to adjust the covered frequency band (especially the low frequency band).

[0090] Optionally, the first direction Y and the second direction X are perpendicular. This allows the bracket 210, the connecting part 230, and the first segment 110 to be arranged horizontally and vertically, simplifying the structure of the antenna device 10.

[0091] Optionally, the connecting part 230 and the bracket 210 are integrally formed. This can improve the stability of the connection between the connecting part 230 and the bracket 210.

[0092] In some optional embodiments, the connecting portion 230 includes two first side surfaces 231 disposed opposite each other along the first direction Y, and the bracket 210 includes a second side surface 211 facing the first segment 110. The angle between the orthographic projection of the first side surface 231 along the third direction Z and the projection of the second side surface 211 along the third direction Z is 90 degrees. The third direction Z is perpendicular to both the first direction Y and the second direction X.

[0093] In these alternative embodiments, the first side 231 and the second side 211 are perpendicular to each other, so that the connecting part 230 and the bracket 210 can be arranged horizontally and vertically, which simplifies the structure of the antenna device 10.

[0094] In some alternative embodiments, the first segment 110 includes a third side 111 facing the bracket 210, and the angle between the orthographic projection of the first side 231 along the third direction Z and the projection of the third side 111 along the third direction Z is 90 degrees.

[0095] In these alternative embodiments, the first side 231 and the third side 111 are perpendicular, so that the connecting portion 230 and the first segment 110 can be arranged horizontally and vertically, which simplifies the structure of the antenna device 10.

[0096] In some alternative embodiments, the orthographic projection of the second side 211 along the third direction Z is parallel to the projection of the third side 111 along the third direction Z. This simplifies the structure of the antenna device 10.

[0097] In some alternative embodiments, such as Figure 6 As shown, the antenna device 10 also includes an extension 240, which is connected to the side of the bracket 210 away from the first segment 110 and extends in a direction away from the first segment 110.

[0098] In these alternative embodiments, an extension 240 is further provided on the side of the bracket 210 away from the first segment 110. This can increase the current flow distance in the extension 240 and the bracket 210, adjust the performance of the first antenna module 301, and enable the first antenna module 301 to cover lower frequency bands. It also allows for better and more flexible design of the current in the first antenna module 301 to achieve better antenna performance.

[0099] Optionally, when the bracket 210 is provided with an extension 240, the aforementioned grounding portion 250 can be connected between the extension 240 and the base plate 130, with the grounding portion 250 connected to the bracket 210 via the extension 240. This can further increase the current flow path length, enabling the first antenna module 301 to cover lower frequency bands. Furthermore, the grounding portion 250 can also alter the current distribution of the base plate 130, concentrating the current in the upper part of the base plate 130 in the positive x-direction, i.e., near the first segment 110, so that the antenna radiation is more directed towards the top, thereby improving the wireless signal transmission and reception capabilities towards the top and enhancing the wireless communication performance of mobile terminals and satellites.

[0100] Optionally, the extension dimension of the extension 240 in the second direction X is smaller than the extension dimension of the bracket 210 in the first direction Y. This is to extend the current flow distance between the bracket 210 and the first segment 110, thereby improving the performance of the first antenna module 301 (e.g., low-frequency band coverage).

[0101] Optionally, when the antenna device 10 further includes the aforementioned connecting portion 230, the extension portion 240 and the connecting portion 230 are spaced apart along the first direction Y. This allows current to flow through the first segment 110, the connecting portion 230, the bracket 210, and the extension portion 240, further increasing the current flow path length and enabling the first antenna module 301 to cover lower frequency bands.

[0102] Optionally, the extension dimension of the extension portion 240 in the second direction X and the extension dimension of the connecting portion 230 in the second direction X may be the same or different.

[0103] Optionally, the extension 240 and the bracket 210 are integrally formed to improve the stability of the connection between the extension 240 and the bracket 210.

[0104] Optionally, the extension 240 extends along the second direction X. Optionally, the first direction Y and the second direction X are perpendicular. This allows the bracket 210, the extension 240, and the first segment 110 to be arranged horizontally and vertically, simplifying the structure of the antenna device 10.

[0105] In some optional embodiments, the extension 240 includes two fourth side surfaces 241 disposed opposite each other along the first direction Y, and the bracket 210 includes a second side surface 211 facing the first segment 110. The angle between the orthographic projection of the fourth side surface 241 along the third direction Z and the projection of the second side surface 211 along the third direction Z is 90 degrees. The third direction Z is perpendicular to both the first direction Y and the second direction X.

[0106] In these alternative embodiments, the fourth side 241 and the second side 211 are perpendicular to each other, so that the connecting part 230 and the bracket 210 can be arranged horizontally and vertically, which simplifies the structure of the antenna device 10.

[0107] In some alternative embodiments, such as Figures 1 to 6 As shown, the antenna assembly 300 also includes a second antenna module 302 disposed on the bracket 210, and the second antenna module 302 includes a plurality of second antenna elements 310.

[0108] In these alternative embodiments, by providing a second antenna module 302, the wireless performance of the antenna device 10 can be improved, and the functions and performance of the antenna device 10 can be enriched.

[0109] Optionally, the multiple second antenna units 310 can also be arranged in multiple rows and columns on the bracket 210. The second antenna units 310 in adjacent rows can be aligned or staggered. This embodiment of the application illustrates the example of the second antenna units 310 being arranged in a single row.

[0110] At least two second antenna units 310 are distributed at intervals along the first direction Y on the bracket 210. By setting multiple second antenna units 310, the signal transmission capability of the second antenna module 302 can be improved, that is, the antenna performance of the second antenna module 302 can be enhanced.

[0111] In some alternative embodiments, such as Figure 7 As shown, when the antenna device 10 includes the aforementioned connecting portion 230, at least one second antenna unit 310 may be disposed on the connecting portion 230. For example, one second antenna unit 310 may be disposed on the connecting portion 230, or at least two second antenna units 310 may be disposed at intervals along the second direction X on the connecting portion 230.

[0112] In these optional embodiments, adding one or more second antenna units 310 to the connection portion 230 can increase the number of second antenna units 310 distributed. Furthermore, the distribution of two or more second antenna units 310 along the length direction of the connection portion 230 can further increase the number of second antenna units 310 distributed, thereby improving the performance of the second antenna module 302.

[0113] In some alternative embodiments, such as Figure 8 As shown, when the antenna device 10 includes the aforementioned extension 240, at least one second antenna unit 310 can be disposed on the extension 240. For example, one second antenna unit 310 may be disposed on the extension 240, or at least two second antenna units 310 may be disposed at intervals along the second direction X on the extension 240. In these optional embodiments, adding one or more second antenna units 310 to the extension 240 can increase the number of second antenna units 310 distributed, and the distribution of two or more second antenna units 310 along the length direction of the extension 240 can further increase the number of second antenna units 310 distributed, thereby improving the performance of the second antenna module 302.

[0114] Furthermore, by adding multiple second antenna units 310 to the connection portion 230 and / or extension portion 240, the spatial range of the antenna radiation beam scanning and coverage of the second antenna module 302 can be expanded, thereby reducing wireless communication blind spots and significantly improving the user's wireless communication experience.

[0115] There are multiple ways to configure the first antenna module 301 and the second antenna module 302. For example, one of the first antenna module 301 and the second antenna module 302 can be a millimeter-wave antenna module and the other can be a non-millimeter-wave antenna module, so that the antenna assembly 300 can transmit and receive millimeter-wave signals and non-millimeter-wave signals.

[0116] In some optional embodiments, the second antenna module 302 is a millimeter-wave antenna module, and the second antenna unit 310 is used to transmit and receive millimeter-wave antenna signals. The second antenna unit 310, mounted on the bracket 210, offers greater flexibility in its size, allowing it to be configured as a smaller, suitable size capable of transmitting and receiving millimeter-wave antenna signals. And / or, the first antenna module 301 is a non-millimeter-wave antenna module, used to transmit and receive non-millimeter-wave antenna signals.

[0117] In this embodiment, when the first antenna module 301 is used to transmit and receive non-millimeter-wave antenna signals and the second antenna module 302 is used to transmit and receive millimeter-wave antenna signals, the antenna assembly 300 can transmit and receive both millimeter-wave and non-millimeter-wave signals, thus enriching the functionality of the antenna assembly 300.

[0118] In some alternative embodiments, such as Figures 1 to 8 As shown, the second antenna module 302 includes a substrate 320 and a second integrated circuit 330. The substrate 320 is disposed on the bracket 210, the second antenna unit 310 is located on the side of the substrate 320 away from the bracket 210, and the second integrated circuit 330 is disposed on the side of the substrate 320 facing the bracket 210.

[0119] In these alternative embodiments, the second antenna module 302 includes a substrate 320, one side of which is used to mount the second integrated circuit 330 and the other side is used to mount the second antenna unit 310. The second antenna unit 310 and the second integrated circuit 330 can be integrated onto the bracket 210 via the substrate 320.

[0120] Furthermore, since the bracket 210 incorporates conductive material, it exhibits excellent heat dissipation. The second integrated circuit 330 does not require an additional heat sink component, meaning no additional heat dissipation metal is needed for it. This reduces the cost and space occupied by the heat sink, enhancing the compactness of the overall system design and achieving better overall system competitiveness.

[0121] Optionally, the second antenna module 302 also includes a shield 340, which is connected to and encloses the substrate 320 to form a receiving cavity, and the second integrated circuit 330 is located in the receiving cavity.

[0122] In these possible embodiments, the antenna device 10 is further provided with a shielding cover 340, which together with the substrate 320 forms a receiving cavity, and the second integrated circuit 330 is located in the receiving cavity, so that the substrate 320 and the shielding cover 340 can provide more comprehensive protection to the second integrated circuit 330, reduce the electromagnetic interference of the second integrated circuit 330 to the external environment, or the electromagnetic interference of the second integrated circuit 330 to the external environment, and provide the second integrated circuit 330 with protection such as waterproofing, dustproofing, and impact resistance.

[0123] Optionally, the antenna assembly 300 further includes a connection terminal 350 disposed on the bracket 210 and connected to the second integrated circuit 330, so that the second integrated circuit 330 can be electrically connected to an external source via the connection terminal 350 for signal transmission. The connection terminal 350 is disposed on the side of the substrate 320 facing the bracket 210, that is, the connection terminal 350 and the second integrated circuit 330 are spaced apart on the same side of the substrate 320.

[0124] In these alternative embodiments, the second integrated circuit 330 can be electrically connected to an external source via the connection terminal 350. For example, the second integrated circuit 330 can be electrically connected to the control motherboard of a wireless mobile terminal via the connection terminal 350. The fact that the connection terminal 350 and the second integrated circuit 330 are located on the same side of the substrate 320 reduces the distance between them, facilitating electrical connection between the second integrated circuit 330 and the connection terminal 350.

[0125] Optionally, the connecting terminal 350 and the shield 340 are spaced apart along the extension direction of the bracket 210 (i.e., the first direction Y). When the shield 340 is covered after the second integrated circuit 330 is installed, the situation where the shield 340 is not positioned correctly and bumps into the connecting terminal 350 can be improved.

[0126] Optionally, the substrate 320 includes a first region 321 and a second region 322 that are interconnected. The first region 321 is located on the support 210, and the second region 322 extends out of the support 210. The second integrated circuit 330 is disposed in the first region 321, and the connection terminal 350 is disposed in the second region 322.

[0127] In these embodiments, the connection terminal 350 is disposed in the second region 322, such that the connection terminal 350 can extend out of the bracket 210 to facilitate electrical connection between the connection terminal 350 and external devices.

[0128] In addition, the second region 322 extends out of the bracket 210, which can further extend the current length and further enhance the signal transmission capability of the first antenna module 301, enabling the first antenna module 301 to better cover the low frequency band.

[0129] like Figures 1 to 8 An embodiment of the first aspect of this application provides an antenna device 10, which includes: a frame 100 enclosing a hollow space 120 and including a first segment 110 extending along a first direction Y; a bracket 210 connected to the first segment 110 on one side of a second direction X and located in the hollow space 120, wherein the bracket 210 is not perpendicular to the first direction Y in its length direction; and an antenna assembly 300 including a first antenna module 301, wherein the materials of the bracket 210 and the first segment 110 both include conductive materials and are reused as at least a portion of the first antenna module 301.

[0130] The length direction of the bracket 210 can be the direction in which the bracket 210 extends to its maximum extent. For example, as Figure 1As shown, the bracket 210 can be extended along the first direction Y, which can be the length direction of the bracket 210. The difference between the bracket 210 in this embodiment and the bracket 210 in the previous embodiment is that the angle between the length direction of the bracket 210 and the first direction Y can be greater than or equal to 0 degrees and less than or equal to 180 degrees, and the angle between the length direction of the bracket 210 and the first direction Y is not 90 degrees. Compared to the scheme where the length direction of the bracket 210 is perpendicular to the first direction Y, this reduces the distance from the end of the bracket 210 away from the first segment 110, making it easier to set the overall distance between the bracket 210 and the first segment 110 closer. This results in a more concentrated current distribution near the first segment 110, allowing the antenna radiation to be more directed towards the top, thereby improving the wireless signal transmission and reception capabilities towards the top and enhancing the wireless communication performance of the mobile terminal and satellite. Therefore, this embodiment can improve the wireless communication performance of the wireless mobile terminal.

[0131] The second aspect of this application also provides a wireless mobile terminal, including the antenna device 10 of any of the first aspect embodiments described above. Since the wireless mobile terminal provided in the second aspect of this application includes the antenna device 10 of any of the first aspect embodiments described above, it has the beneficial effects of the antenna device 10 of any of the first aspect embodiments described above, which will not be elaborated further here.

[0132] The wireless mobile terminals in this application include, but are not limited to, mobile phones, personal digital assistants (PDAs), tablets, e-readers, televisions, access control systems, smart landline phones, control consoles, and other devices with wireless communication capabilities.

[0133] Optionally, the wireless mobile terminal further includes a functional device, the housing of which is reused with at least a portion of the first segment 110. That is, at least a portion of the housing of the functional device can be reused as part of the first antenna module 301, further simplifying the structure of the display panel. The functional device may be, for example, a camera assembly, a fingerprint recognition assembly, etc.

[0134] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
