Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the inventor based on the embodiments herein, are within the scope of the protection of the present application.

Referring to fig. 1, fig. 2, and fig. 3, the electronic device 10 provided in the embodiment of the present application includes a first antenna module 110, a housing 200, and a reflector 300, where the first antenna module 110 includes a first radiation surface 110a, the first radiation surface 110a is provided with a first radiator 111, and the first radiator 111 is configured to receive and transmit a radio frequency signal in a first preset frequency band; the housing 200 is located at one side of the first antenna module 110, the housing 200 has a target area 201, the target area 201 is used for transmitting the radio frequency signal of the first preset frequency band, and the target area 201 deviates from the radiation direction range of the first radiator 111; the reflecting member 300 includes a reflecting surface 300a having a preset included angle with the first radiating surface 110a, where the reflecting surface 300a is configured to reflect the radio frequency signal in the first preset frequency band emitted by the first radiator 111, so that the radio frequency signal in the first preset frequency band after being reflected is radiated to a free space through the target area 201; the reflecting surface 300a is further configured to reflect the radio frequency signal of the first preset frequency band radiated from the free space through the target area 201 to the reflecting surface 300a toward the first radiating surface 110 a.

The electronic device 10 may be any device having communication functions. For example: tablet personal computers, mobile phones, electronic readers, remote controllers, personal computers (Personal Computer, PCs), notebook computers, vehicle-mounted devices, network televisions, wearable devices and other intelligent devices with communication functions.

The first preset frequency band at least comprises a 3GPP millimeter wave full frequency band. The first antenna module 110 may include one antenna radiator, or may be an antenna array formed by a plurality of antenna radiators. The first antenna module 110 may be a 1×2 antenna array, a 2×2 antenna array, a 2×4 antenna array, or a 4×4 antenna array. When the first antenna module 110 includes a plurality of antenna radiators, the plurality of antenna radiators can operate in the same frequency band. The plurality of antenna radiators can also operate in different frequency bands, which is helpful for expanding the frequency band range of the first antenna module 110.

The target area 201 of the housing 200 may be penetrated by the radio frequency signal of the first preset frequency band, but the target area 201 of the housing 200 deviates from the radiation direction range of the radio frequency signal of the first preset frequency band transmitted by the first radiator 111, and the reflecting member 300 is located in the radiation direction range of the radio frequency signal of the first preset frequency band transmitted by the first radiator 111, and the reflecting surface 300a of the reflecting member 300 may reflect the radio frequency signal of the first preset frequency band transmitted by the first radiator 111, so that the radio frequency signal of the first preset frequency band after reflection is transmitted towards the target area 201 of the housing 200, and is further radiated to the free space through the target area 201. In addition, the radio frequency signal of the first preset frequency band transmitted to the reflecting member 300 through the target area 201 of the housing 200 may be transmitted toward the first radiation surface 110a after being reflected by the reflecting surface 300a of the reflecting member 300, so that the first radiator 111 may receive the radio frequency signal of the first preset frequency band conveniently. The deviation of the target area 201 of the housing 200 from the radiation direction range of the first radiator 111 for receiving and transmitting the radio frequency signal of the first preset frequency band means that the radiation directions of the target area 201 of the housing 200 and the first radiator 111 for receiving and transmitting the radio frequency signal of the first preset frequency band do not overlap spatially. The free space may be considered as a radiation space where the radio frequency signal is not blocked, e.g., a space on a side of the housing 200 facing away from the first antenna module 110.

In an embodiment, the target area 201 may be a local area of the housing 200, where the target area 201 may be penetrated by a radio frequency signal of a first preset frequency band, that is, an area corresponding to a part of the structure of the housing 200 forms the target area 201, and other areas of the housing 200 except for the target area 201 have a shielding effect on the radio frequency signal of the first preset frequency band, where at this time, the materials of the target area 201 of the housing 200 and other areas of the housing 200 except for the target area 201 are different, so that the processing technology of the housing 200 is more flexible. For example, the material corresponding to the target area 201 of the housing 200 may be a non-shielding material, specifically, plastic, glass or ceramic, and the material of the other area except the target area 201 of the housing 200 may be a shielding material, specifically, a metal material.

In another embodiment, the target area 201 may be an entire area of the housing 200, that is, an area corresponding to the entire structure of the housing 200 constitutes the target area 201, and the entire housing 200 may be penetrated by the radio frequency signal of the first preset frequency band, where the material corresponding to the target area 201 of the housing 200 is a non-shielding material, and may specifically be plastic, glass or ceramic.

In the electronic device 10 provided in this embodiment, the target area 201 of the housing 200 may be penetrated by the radio frequency signal of the first preset frequency band, but the target area 201 of the housing 200 deviates from the radiation direction range of the radio frequency signal of the first preset frequency band transmitted and received by the first radiator 111, and the reflector 300 is disposed in the radiation direction range of the radio frequency signal of the first preset frequency band transmitted and received by the first radiator 111, and the reflector 300 has the reflecting surface 300a, and the radio frequency signal of the first preset frequency band transmitted by the first radiator 111 is reflected by the reflecting surface 300a, so that the radio frequency signal of the first preset frequency band after reflection is radiated to the free space through the target area 201 of the housing 200, thereby improving the quality of the radio frequency signal of the first preset frequency band transmitted by the first radiator 111. In addition, when the radio frequency signal of the first preset frequency band radiates from the free space through the target area 201 of the housing 200 toward the reflecting surface 300a, the reflecting surface 300a is further configured to reflect the radio frequency signal of the first preset frequency band toward the first radiating surface 110a, so that the first radiator 111 receives the radio frequency signal of the first preset frequency band after being reflected, thereby improving the quality of the radio frequency signal of the first preset frequency band received by the first radiator 111.

In addition, when the radio frequency signal of the first preset frequency band penetrating through the target area 201 of the back plate 210 is transmitted to the reflector 300 or the frame 220, the radio frequency signal of the first preset frequency band is transmitted toward one side of the first radiator 111 after one or more reflections between the reflector 300 and the frame 220, so that the first radiator 111 receives the radio frequency signal of the first preset frequency band.

With continued reference to fig. 5 and fig. 6, the reflecting surface 300a is configured to reflect the radio frequency signal in the first preset frequency band emitted by the first radiator 111 toward one side of the target area 201 of the back plate 210, and when the reflecting surface 300a is a curved surface, the reflecting surface 300a has a center of curvature, where the center of curvature faces one side of the back plate 210, or the center of curvature faces one side facing away from the back plate 210.

Specifically, in this embodiment, the reflecting surface 300a of the reflecting member 300 is configured to reflect the radio frequency signal in the first preset frequency band. In one embodiment, the reflecting surface 300a is a curved surface, and the curvature center of the reflecting surface 300a faces one side of the back plate 210, that is, the reflecting surface 300a is a concave arc surface, when the radio frequency signal of the first preset frequency band emitted by the first radiator 111 is transmitted to the reflecting surface 300a, the concave reflecting surface 300a may reflect the radio frequency signal toward one side of the target area 201 of the back plate 210, so that the radio frequency signal of the first preset frequency band is transmitted through the target area 201 of the back plate 210. In another embodiment, the reflecting surface 300a is a curved surface, and the curvature center of the reflecting surface 300a faces to a side facing away from the back plate 210, that is, the reflecting surface 300a is an arc surface with a convex shape, when the radio frequency signal of the first preset frequency band emitted by the first radiator 111 is transmitted to the reflecting surface 300a, the convex reflecting surface 300a can reflect the radio frequency signal of the first preset frequency band toward a side of the target area 201 of the back plate 210, so that the radio frequency signal of the first preset frequency band is transmitted through the target area 201 of the back plate 210.

It can be appreciated that in other embodiments, the reflecting surface 300a may be a non-standard curved surface, that is, the reflecting surface 300a does not have a constant curvature center, and the radio frequency signal in the first preset frequency band may be transmitted toward the target area 201 of the back plate 210 after being reflected on the reflecting surface 300a for multiple times.

With continued reference to fig. 7, the reflecting member 300 includes a reflecting body 310 and an isolation coating 320 disposed on the reflecting body 310, where the isolation coating 320 at least partially forms the reflecting surface 300a, and is configured to reflect the radio frequency signal of the first preset frequency band emitted by the first radiator 111 toward one side of the target area 201.

Specifically, the reflective body 310 forms a bearing substrate, and the isolation coating 320 is carried on the reflective body 310 to reflect the radio frequency signal of the first preset frequency band emitted by the first radiator 111, so that the radio frequency signal of the reflected first preset frequency band is transmitted toward the target area 201 of the back plate 210. The isolation coating 320 may be a metal coating, the reflective body 310 may be made of the same material as the isolation coating 320, and the reflective body 310 may be made of a different material from the isolation coating 320.

With continued reference to fig. 8, the electronic device 10 includes a main board 400, the reflector 300 is supported on the main board 400, the main board 400 and the back board 210 are disposed at intervals, the main board 400 is located in the accommodating space S, the first antenna module 110 is electrically connected to the main board 400, the main board 400 and the back board 210 are disposed at intervals, and at least part of the main board 400 forms the reflector 300. The main board 400 is configured to reflect the radio frequency signal of the first preset frequency band emitted by the first radiator 111, so that the radio frequency signal of the first preset frequency band after being reflected is radiated to free space through the target area 201; the main board 400 is further configured to reflect, toward the first radiation surface 110a, a radio frequency signal of a first preset frequency band that is radiated from the free space to the main board 400 through the target area 201.

The main board 400 is located in the accommodating space S, the first radiator 111 is electrically connected to the main board 400, the main board 400 is located at a side of the first radiator 111 away from the back board 210, and the main board 400 and the reflecting member 300 cooperate to reflect the radio frequency signal of the first preset frequency band emitted by the first radiator 111 toward a side of the target area 201.

The main board 400 is a circuit board of the electronic device 10, the main board 400 is electrically connected with the first radiator 111, and the first radiator 111 receives and transmits radio frequency signals of a first preset frequency band under the control of the main board 400. The main board 400 is located at a side of the first radiator 111 facing away from the back board 210, when the radio frequency signal of the first preset frequency band emitted by the first radiator 111 is transmitted towards the main board 400 or the direction of the reflective member 300, the radio frequency signal of the first preset frequency band may be transmitted towards the target area 201 of the back board 210 under the reflection effect of the main board 400, or the radio frequency signal of the first preset frequency band may be transmitted towards the target area 201 of the back board 210 under the reflection effect of the reflective member 300, or the radio frequency signal of the first preset frequency band may be transmitted towards the target area 201 of the back board 210 after one or more interaction of the reflective member 300 and the main board 400.

With continued reference to fig. 9, the electronic device 10 further includes a bracket 450 and a second antenna module 120, where the bracket 450 is fixed on the motherboard 400, the second antenna module 120 includes a second radiator 121, the second radiator 121 is fixed on the bracket 450, at least part of the second radiator 121 forms the reflecting surface 300a, and a radiation direction of the second radiator 121 at least partially covers the target area 201.

The bracket 450 may be a plastic bracket 450, and the bracket 450 is fixed to the main board 400 for supporting the reflector 300. When the second radiator 121 at least partially forms the reflecting surface 300a of the reflecting member, the bracket 450 may increase a headroom area of the second radiator 121, so that the radiation efficiency of the second radiator 121 may be improved.

Specifically, the second radiator 121 may be formed by a Laser-Direct-structuring (LDS) technique. At this time, the second radiator 121 forms a reflecting surface 300a for reflecting the radio frequency signal emitted from the first radiator 111, and forms the second radiator 121, thereby realizing the function related to the antenna, and realizing the function multiplexing of the second radiator 121.

Further, the first radiator 111 and the second radiator 121 operate in different frequency bands, and in particular, in one embodiment, the first radiator 111 is configured to transmit and receive radio frequency signals in a first frequency band, and the second radiator 121 is configured to transmit and receive radio frequency signals in a second frequency band. In one embodiment, the first frequency band is consistent with the second frequency band, and at this time, the rf signal reflected by the reflecting element 300 is radiated to the free space through the target area 201, which helps to enhance the intensity of the rf signal.

In another embodiment, the first frequency band is different from the second frequency band, and at this time, the radio frequency signal reflected by the reflecting element 300 is radiated to the free space through the target area 201, so as to facilitate the receiving and transmitting of the dual-band radio frequency signal. The radio frequency signal of the first frequency band can be a millimeter wave antenna, and the radio frequency signal of the second frequency band can be a sub 6GHz radio frequency signal.

According to the 3gpp TS 38.101 protocol provision, 5G mainly uses two segments of frequencies: FR1 band and FR2 band. The frequency range of the FR1 frequency band is 450 MHz-6 GHz, which is also called sub-6GHz frequency band; the frequency range of the FR2 band is 24.25 GHz-52.6 GHz, commonly known as millimeter Wave (mm Wave). The 3GPP 15 release specifies the current 5G millimeter wave band as follows: n257 (26.5-29.5 GHz), n258 (24.25-27.5 GHz), n261 (27.5-28.35 GHz) and n260 (37-40 GHz). The first frequency band can cover 24.25 GHz-52.6 GHz frequency band, and at this time, the second frequency band can cover 450 MHz-6 GHz frequency band. The first radiator 111 may be a millimeter wave antenna module, and the second radiator 121 may be a sub 6GHz antenna module.

In one embodiment, the first radiator 111 operates in the first frequency band, and the first radiator 111 is a directional antenna; when the second radiator 121 works in the second frequency band, the second radiator 121 is an omni-directional antenna.

Specifically, since the frequency range of the first frequency band is 24.25GHz to 52.6GHz, and the frequency range of the second frequency band is 450MHz to 6GHz, the radio frequency signal of the first frequency band has a shorter wavelength and is suitable for a scene with a higher density, and when the first radiator 111 works in the first frequency band, the first radiator 111 is a directional antenna. At this time, the advantage of the antenna module can be exerted. The radio frequency signal of the second frequency band has longer wavelength, can better cross the barrier, is suitable for long-distance transmission, and when the second radiator 121 works in the second frequency band, the second radiator 121 is an omni-directional antenna, and can cover a larger radiation range.

Further, because the difference between the radio frequency signals of the first frequency band and the radio frequency signals of the second frequency band is larger, the problem of coupling is not easy to occur between the radio frequency signals of the first frequency band and the radio frequency signals of the second frequency band, so that the radio frequency signals of the first frequency band and the radio frequency signals of the second frequency band transmitted and received by the first radiator 111 and the radio frequency signals of the second frequency band transmitted and received by the second radiator 121 can be performed simultaneously, the problems of mutual coupling and mutual interference cannot occur, and the first radiator 111 and the second radiator 121 can work in different frequency bands simultaneously at the moment, so that the application range of the antenna module is widened. In addition, the coexistence problem of the millimeter wave signal transmitted and received by the first radiator 111 and the sub 6GHz radio frequency signal transmitted and received by the second radiator 121 can be solved.

With continued reference to fig. 10, the second radiator 121 includes a first section 301 and a second section 302 that are connected, where a radiation direction of the first section 301 is at least partially toward the first radiator 111, the first section 301 forms the reflecting surface 300a, the first section 301 is configured to reflect a radio frequency signal in a first preset frequency band emitted by the first radiator 111, and a radiation direction of the second radiator 121 is at least partially toward the target area 201.

Specifically, the first section 301 and the reflecting element 300 are mutually matched to reflect the radio frequency signal in the first preset frequency band emitted by the first radiator 111, and the radio frequency signal in the first preset frequency band is transmitted toward the target area 201 of the back plate 210 after being reflected between the first section 301 and the reflecting element 300 for one or more times. In an embodiment, the radiation direction of the second radiator 121 faces the target area 201 of the housing 200, and at this time, the radio frequency signal emitted by the second radiator 121 may directly penetrate the target area 201. In another embodiment, the radio frequency signal emitted from the second radiator 121 is reflected by the reflecting member 300 or the first segment 301 and then transmitted toward the target area 201 of the housing 200. By segmenting the second radiator 121 and using different segments for implementing different functions, which is equivalent to integrating structures of different functions, the internal space of the electronic device 10 can be saved.

With continued reference to fig. 11, the electronic device 10 further includes a battery 500 and a battery compartment 510, wherein the battery 500 is accommodated in the battery compartment 510, and the battery compartment 510 at least partially forms the reflecting member 300.

Specifically, in one embodiment, the battery compartment 510 at least partially forms the reflecting member 300, that is, the radio frequency signal emitted by the first radiator 111 is transmitted toward the battery compartment 510, and is transmitted through the target area 201 of the back plate 210 after being reflected by the battery compartment 510. The reflecting member 300 forms a battery compartment 510 for accommodating the battery 500, and is used for reflecting the radio frequency signal of the first preset frequency band emitted by the first radiator 111, at this time, without additional arrangement of other reflecting structures, the reflecting function of the radio frequency signal of the first preset frequency band can be realized by multiplexing the reflecting member 300, so that the radio frequency signal of the first preset frequency band is radiated to the free space through the target area 201 of the back plate 210.
