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 preset frequency band at least comprises a 3GPP millimeter wave full frequency band. The antenna module 300 may include one antenna radiator or an antenna array formed by a plurality of antenna radiators. The antenna module 300 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 antenna module 300 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 antenna module 300.
The frame 100 and the backplate 200 are two mutually independent structures, the frame 100 is a shielding material, specifically, the frame 100 may be a metal material, the frame 100 has a shielding effect on a radio frequency signal of a preset frequency band, the radio frequency signal of the preset frequency band cannot penetrate the frame 100, a part or a whole of the backplate 200 is an unshielded material, that is, the local structure of the backplate 200 is an unshielded part 210, at this time, other structures of the backplate 200 except the unshielded part 210 may be shielding materials, or the whole backplate 200 is an unshielded part 210, and the unshielded part 210 of the backplate 200 may be penetrated by the radio frequency signal of the preset frequency band. The backplate 200 and the frame 100 enclose a housing space S, and the antenna module 300 is located in the housing space S.
In an embodiment, the reflecting member 400 is located in a radiation direction range of the antenna module 300 for receiving and transmitting the radio frequency signal of the preset frequency band, when the first radiator 310 emits the radio frequency signal in a direction of the reflecting surface 400a, the reflecting surface 400a can reflect the radio frequency signal of the preset frequency band emitted by the first radiator 310 toward one side of the non-shielding portion 210 of the backplate 200, and the radio frequency signal of the preset frequency band after being reflected is radiated to the free space through the non-shielding portion 210 of the backplate 200. In addition, when the radio frequency signal of the preset frequency band is transmitted from the non-shielding portion 210 of the free space penetrating back plate 200 toward the reflecting surface 400a, the reflecting surface 400a may reflect the radio frequency signal of the preset frequency band penetrating from the free space penetrating the non-shielding portion 210 toward the radiating surface 300 a. Wherein the position of the reflecting member 400 within the radiation direction range of the first radiator 310 means that the position of the reflecting member 400 spatially overlaps with the radiation direction of the radio frequency signal radiated by the first radiator 310. The free space may be considered as a radiation space where radio frequency signals are not blocked, e.g., a space on a side of the backplate 200 facing away from the antenna module 300.
In another embodiment, the reflecting member 400 and the frame 100 are both located in a radiation direction range of the radio frequency signal of the preset frequency band transmitted by the first radiator 310, and the reflecting member 400 is located between the frame 100 and the antenna module 300, when the radio frequency signal of the preset frequency band is transmitted by the first radiator 310 towards the frame 100, the reflecting surface 400a can reflect the radio frequency signal transmitted by the first radiator 310 towards one side of the non-shielding portion 210 of the backplate 200, and the radio frequency signal of the preset frequency band is radiated to the free space through the non-shielding portion 210 of the backplate 200. In addition, when the radio frequency signal of the preset frequency band is transmitted from the free space through the non-shielding portion 210 of the backplate 200 toward the reflective surface 400a, the reflective surface 400a may reflect the radio frequency signal of the preset frequency band radiated from the free space to the non-shielding portion 210 toward the first radiator 310.
In still another embodiment, the reflecting member 400 and the frame 100 are both located in a radiation direction range of the radio frequency signal of the preset frequency band transmitted by the first radiator 310, when the radio frequency signal is transmitted by the first radiator 310 in a direction of the frame 100 and/or the reflecting surface 400a, the radio frequency signal of the preset frequency band transmitted by the first radiator 310 can be reflected by the frame 100 and/or the reflecting surface 400a toward one side of the non-shielding portion 210 of the backplate 200, and one or more times of mutual reflection can be performed between the frame 100 and the reflecting surface 400a, so that the radio frequency signal of the preset frequency band is radiated to the free space through the non-shielding portion 210 of the backplate 200. In addition, when the radio frequency signal of the preset frequency band is transmitted from the non-shielding portion 210 of the free space penetrating back plate 200 toward the reflecting surface 400a, the reflecting member 400 may reflect the radio frequency signal of the preset frequency band penetrating from the free space penetrating the non-shielding portion 210 toward the radiating surface 300 a.
In the electronic device 10 provided in this embodiment, the reflection member 400 is disposed in the radiation direction range of the radio frequency signal of the preset frequency band transmitted by the antenna module 300, the radio frequency signal of the preset frequency band transmitted by the first radiator 310 is reflected towards one side of the non-shielding portion 210 of the backplate 200 by the reflection surface 400a of the reflection member 400, so that the radio frequency signal of the preset frequency band penetrates through the non-shielding portion 210 to radiate to free space, and the reflection surface 400a can reflect the radio frequency signal of the preset frequency band penetrating through the non-shielding portion 210 of the backplate 200 from the free space towards the radiation surface 300a, thereby improving the quality of the radio frequency signal transmitted by the antenna module 300.
In one embodiment, when the radiation direction of the first radiator 310 is toward a side facing away from the bezel 100, the reflector 400 is located at a side of the first radiator 310 facing away from the bezel 100.
Specifically, the frame 100 deviates from the radiation direction of the antenna module 300, the reflecting member 400 is located in the radiation direction range of the antenna module 300, and when the radio frequency signal emitted by the antenna module 300 is transmitted toward the reflecting member 400, the reflecting member 400 may reflect the radio frequency signal from the antenna module 300, so that the reflected radio frequency signal is transmitted toward the non-shielding portion 210 of the backplate 200 and penetrates the non-shielding portion 210. Because the direction of the radio frequency signal radiated by the antenna module 300 deviates from the frame 100, the diffuse reflection of the radio frequency signal radiated by the antenna module 300 by the frame 100 can be avoided, and thus the problem of reducing the radiation quality of the antenna module 300 can be avoided.
With continued reference to fig. 4, in one embodiment, the radiation direction of the first radiator 310 faces to a side away from the frame 100, and the first radiator 310 is fixed to the frame 100, and the frame 100 is configured to transfer heat of the first radiator 310 to the outside of the accommodating space S.
Specifically, the radiation direction of the radio frequency signal of the first radiator 310 for receiving and transmitting the radio frequency signal of the preset frequency band is away from the frame 100, the antenna module 300 is fixed on the frame 100, the first radiator 310 radiates the radio frequency signal towards the inside of the accommodating space S, and the heat generated during the operation of the first radiator 310 can be transferred to the outside of the accommodating space S through the frame 100, so that the heat dissipation effect on the first radiator 310 is achieved.
With continued reference to fig. 5, the reflecting surface 400a is configured to reflect the radio frequency signal in the preset frequency band emitted by the first radiator 310 toward the side of the non-shielding portion 210 of the backplate 200, and when the reflecting surface 400a is a plane and the side surface of the bezel 100 is perpendicular to the plane of the backplate 200, the acute angle degree of the dihedral angle formed between the plane of the reflecting surface 400a and the side surface of the bezel 100 is 45 degrees, and the acute angle degree of the dihedral angle formed between the plane of the reflecting surface 400a and the plane of the backplate 200 is also 45 degrees.
With continued reference to fig. 6, in another embodiment, when the radiation direction of the first radiator 310 is toward one side of the frame 100, the reflector 400 is located between the antenna module 300 and the frame 100.
Specifically, the reflecting member 400 is located between the antenna module 300 and the frame 100, the reflecting member 400 is located in a radiation direction range of the first radiator 310 for receiving and transmitting radio frequency signals in a preset frequency band, and at least part of the frame 100 is located in a radiation direction range of the first radiator 310 for receiving and transmitting radio frequency signals in the preset frequency band. In one embodiment, when the first radiator 310 radiates the radio frequency signal of the preset frequency band toward the reflector 400 and the frame 100, the reflector 400 can reflect the radio frequency signal of the preset frequency band radiated by the first radiator 310 toward the non-shielding portion 210 of the backplate 200, so that the radio frequency signal of the preset frequency band after being reflected radiates to the free space through the non-shielding portion 210 of the backplate 200. At this time, most of the radio frequency signals in the predetermined frequency band are reflected to the non-shielding portion 210 of the backplate 200 via the reflection surface 400a, which is helpful for improving the radiation quality of the antenna module 300.
With continued reference to fig. 7, in another embodiment, the reflecting surface 400a is configured to reflect the radio frequency signal of the preset frequency band emitted by the first radiator 310 toward one side of the frame 100, and the frame 100 is configured to reflect the radio frequency signal of the preset frequency band reflected by the reflecting surface 400a toward the non-shielding portion 210.
Specifically, the reflecting member 400 is located in a radiation direction range of the first radiator 310 for receiving and transmitting the radio frequency signal in the preset frequency band, and at least part of the frame 100 is located in the radiation direction range of the first radiator 310 for receiving and transmitting the radio frequency signal in the preset frequency band. When the first radiator 310 radiates the radio frequency signal of the preset frequency band toward the reflector 400, the reflection surface 400a may reflect the radio frequency signal of the preset frequency band radiated by the first radiator 310 toward the frame 100, and then the frame 100 reflects the radio frequency signal of the preset frequency band toward the non-shielding portion 210 of the backplate 200, so that the radio frequency signal of the preset frequency band radiates to the free space through the non-shielding portion 210 of the backplate 200. That is, after the radio frequency signal in the preset frequency band is reflected by the reflecting surface 400a and the frame 100 together, the radio frequency signal radiates to the free space toward the non-shielding portion 210 of the backplate 200, and the number of reflection times of the radio frequency signal in the preset frequency band between the frame 100 and the reflecting member 400 may be one or more. The radio frequency signal with the preset frequency band may be reflected from the first radiator 310 onto the reflecting surface 400a, then reflected to the frame 100 via the reflecting surface 400a, and then reflected from the frame 100 to the non-shielding portion 210 of the backplate 200. The radio frequency signal with the preset frequency band may be reflected from the first radiator 310 to the frame 100, then reflected to the reflecting member 400 via the frame 100, and then reflected to the non-shielding portion 210 of the backplate 200 by the reflecting member 400.
With continued reference to fig. 8, the reflecting surface 400a is configured to reflect the radio frequency signal of the preset frequency band emitted by the first radiator 310 toward the side of the non-shielding portion 210 of the backplate 200, where the reflecting surface 400a has a curvature center, and when the reflecting surface 400a is a curved surface, the curvature center faces toward the side of the backplate 200, or the curvature center faces toward the side facing away from the backplate 200.
Specifically, in this embodiment, the reflecting surface 400a of the reflecting member 400 is configured to reflect the radio frequency signal in the preset frequency band. In one embodiment, the reflecting surface 400a is a curved surface, and the curvature center of the reflecting surface 400a faces one side of the backplate 200, that is, the reflecting surface 400a is a concave arc surface, when the radio frequency signal of the preset frequency band emitted by the first radiator 310 is transmitted to the reflecting surface 400a, the concave reflecting surface 400a can reflect the radio frequency signal of the preset frequency band toward one side of the non-shielding portion 210 of the backplate 200, so that the radio frequency signal of the preset frequency band is radiated to the free space through the non-shielding portion 210 of the backplate 200. In another embodiment, the reflecting surface 400a is a curved surface, and the curvature center of the reflecting surface 400a faces to a side facing away from the backplate 200, that is, the reflecting surface 400a is an arc surface with a convex shape, when the radio frequency signal of the preset frequency band emitted by the first radiator 310 is transmitted to the reflecting surface 400a, the convex reflecting surface 400a can reflect the radio frequency signal of the preset frequency band toward a side of the non-shielding portion 210 of the backplate 200, so that the radio frequency signal of the preset frequency band is radiated to the free space through the non-shielding portion 210 of the backplate 200.
It can be appreciated that in other embodiments, the reflecting surface 400a may be a non-standard curved surface, that is, the reflecting surface 400a does not have a constant curvature center, and the radio frequency signal in the preset frequency band may be reflected on the reflecting surface 400a for multiple times and then radiated to the free space toward the non-shielding portion 210 of the backplate 200.
With continued reference to fig. 9, the reflecting member 400 includes a reflecting body 410 and an isolation coating 420 disposed on the reflecting body 410, wherein at least a portion of the isolation coating forms the reflecting surface 400a, and the isolation coating 420 is configured to reflect the radio frequency signal of the preset frequency band emitted by the first radiator 310 toward one side of the non-shielding portion 210.

The radio frequency signal of the first frequency band can be a millimeter wave signal, and the radio frequency signal of the second frequency band can be a radio frequency signal of a preset frequency band of sub 6 GHz.
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).

In one embodiment, the first radiator 310 operates in the first frequency band, and the first radiator 310 is a directional antenna; when the second radiator 320 works in the second frequency band, the second radiator 320 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 310 works in the first frequency band, the first radiator 310 is a directional antenna.

Further, because the difference between the radio frequency signals in the first frequency band and the radio frequency signals in the second frequency band is larger, the problem of coupling is not easy to occur between the radio frequency signals in the first frequency band and the radio frequency signals in the second frequency band, so that the radio frequency signals in the first frequency band can be transmitted and received by the first radiator 310 and the radio frequency signals in the second frequency band can be transmitted and received by the second radiator 320 at the same time, the problem of mutual coupling and mutual interference can not occur, and the first radiator 310 and the second radiator 320 at the moment can work in different frequency bands at the same time, so that the application range of the first radiator 310 is enlarged. In addition, the coexistence problem of the millimeter wave signal transmitted and received by the first radiator 310 and the sub 6GHz radio frequency signal transmitted and received by the second radiator 320 can be solved.
The first radiator 310 is disposed on a side of the antenna module 300 facing the frame 100, the reflecting member 400 is disposed between the frame 100 and the antenna module 300, and the second radiator 320 is disposed on a side of the antenna module 300 facing the non-shielding portion 210. In one embodiment, when the first radiator 310 and the second radiator 320 radiate radio frequency signals with the same frequency band, the reflector 400 is used to increase the intensity of the radio frequency signals. In another embodiment, when the first radiator 310 receives and transmits the radio frequency signal in the first frequency band, the second radiator 320 receives and transmits the radio frequency signal in the second frequency band, and the first frequency band is different from the second frequency band, the reflecting member 400 is configured to implement receiving and transmitting of the radio frequency signal in the dual frequency band.
Specifically, the reflecting surface 400a may reflect the radio frequency signal emitted by the first radiator 310, so that the radio frequency signal reflected by the reflecting surface 400a is radiated to the free space through the non-shielding portion 210 of the backplate 200. The radio frequency signal emitted by the second radiator 320 may be directly radiated into the free space through the non-shielding portion 210 of the backplate 200. In one embodiment, when the first radiator 310 and the second radiator 320 radiate radio frequency signals with the same frequency band, the reflecting surface 400a is used to increase the intensity of the radio frequency signals received and transmitted by the antenna module 300. In another embodiment, when the radio frequency signal in the first frequency band transmitted by the first radiator 310 is different from the radio frequency signal in the second frequency band transmitted by the second radiator 320, the reflecting member 400 can realize the transmission and reception of the radio frequency signal in the dual frequency bands, that is, the antenna module 300 can operate in the first frequency band and the second frequency band at the same time.
