The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

Referring to fig. 1-3, an electronic device provided in an embodiment of the present application includes: the antenna comprises a shell 100, a first circuit board 200, a feeder line 300 and a decoration piece 400 with electric conduction performance, wherein the first circuit board 200 is provided with a feed source, and the decoration piece 400 is used for fixing a camera arranged in the shell 100;

the decoration 400 is exposed outside the housing 100, and a radiation groove 401 with an opening facing the outside of the housing 100 is formed on the side wall of the decoration 400;

the feed source is electrically connected with the inner wall of the radiation slot 401 through the feed line 300, and the feed source, the feed line 300 and the decoration 400 jointly form an antenna structure.

The above-mentioned decoration 400 may be a metal decoration frame of a camera of an electronic device, which is used to fix the camera of the electronic device on one hand, and also to seal a gap between the camera and the housing 100 on the other hand, wherein the camera may be a rear camera of the electronic device.

The radiation slot 401 may be a slot formed on a side wall of the decoration 400, and radiate the antenna signal fed by the feed source through the slot

The antenna structure may be various antennas in the electronic device, for example, may be a millimeter wave antenna in the electronic device. In the prior art, the millimeter wave antenna is often an independent antenna module, i.e. is often used as an assembly device. However, the complete machine environments of each terminal model are different, and the antennas with millimeter wave bands are sensitive to the surrounding environments, so that the same antenna module cannot be used in different terminals, and the antenna module is often required to be customized independently, so that the cost is increased to a certain extent, and the product competitiveness is reduced. In the present embodiment, the decoration 400 of the camera is used as the radiator of the millimeter wave antenna, and the decoration 400 is exposed outside the electronic device, so that environments where the decoration 400 of different models is located are generally similar, and therefore, the antenna structure provided in the present embodiment can be commonly used in different types of terminals.

It should be appreciated that the above-described radiation groove 401 is provided at a side wall of a portion of the decoration 400 protruding outside the housing 100, thereby ensuring that the opening of the installation groove 402 is directed to the outside of the housing 100. By directing the opening of the mounting groove 402 toward the outside of the housing 100 so as to radiate signals outwardly through the mounting groove 402 or to receive signals from the outside through the mounting groove 402.

The signals in the feed source can be directly fed into the inner wall of the radiation slot 401 through the feed line 300 to radiate, and of course, external signals can also be received through the radiation slot 401.

In this embodiment, the decoration 400, in which the camera is exposed outside the housing 100, is used as a radiator of the antenna, so that the installation space of the antenna in the electronic device can be effectively increased, and the problem of insufficient installation space of the antenna in the conventional electronic device is solved.

Optionally, a mounting groove 402 for fixing the camera is formed on a side of the decoration 400 facing away from the housing 100, and the radiation groove 401 is communicated with the mounting groove 402.

Specifically, referring to fig. 1, the mounting groove 402 may be a mounting groove 402 for mounting the glass panel 500, at least one mounting hole 403 may be formed on a surface of the decoration 400, and the first circuit board 200 is provided with a communication hole 201 corresponding to the mounting hole 403, so that a lens of the camera may sequentially penetrate through the communication hole 201 and the mounting hole 403, thereby fixing the camera.

Referring to fig. 2, by communicating the radiation slot 401 with the installation slot 402, the radiation slot 401 may transmit and receive signals along a side facing away from the installation slot 402, and may also transmit and receive signals along a side facing toward the installation slot 402, thereby further improving radiation performance of the antenna structure.

Referring to fig. 4, in order to show the reflection coefficient graph of the antenna structure, as can be seen from fig. 4, the antenna structure can cover the frequency range of 24 GHz-26 GHz, and the length of the radiation slot 401 is half of the wavelength corresponding to the center frequency of the antenna structure. The resonant frequency of the antenna structure can be tuned by adjusting the length and the height of the radiating slot 401 and the position and the size of the feeder 300, so as to meet different frequency requirements, and realize the global mainstream 5G millimeter wave frequency bands already defined by 3GPP such as n257, n258, n260, n261 and the like.

In this embodiment, the radiation groove 401 is formed in the side wall of the decorative member 400, so that it is possible to ensure that the radiation groove 401 can transmit and receive signals, and it is also possible to prevent the overall aesthetic appearance of the electronic device from being affected by the formation of the radiation groove 401.

Optionally, the side wall of the decoration 400 is provided with at least two radiation slots 401 arranged at intervals, and the feed source is electrically connected with each radiation slot 401 through a feeder 300 respectively.

Specifically, at least two radiation grooves 401 are formed on the side wall of the decoration 400 at intervals, so that an antenna array can be formed by the at least two radiation grooves 401, and the signal radiation effect of the antenna structure can be further improved. Wherein, each antenna unit has a certain distance, and the distance between two adjacent radiation slots 401 can be determined by the resonant frequency of the antenna, the gain of the array, the scanning angle and other antenna performances.

In the implementation, the feed source and the at least one radiating slot 401 may be connected through one feed source, and of course, the feed source and the different radiating slots 401 may also be connected through different feed lines 300. The at least two radiation grooves 401 may be formed in the same side wall of the decoration 400, and of course, the at least two radiation grooves 401 may also be formed in different side walls of the decoration 400, for example, the at least two radiation grooves 401 may be circumferentially spaced around the decoration 400.

In this embodiment, at least one of the radiation grooves 401 of the decoration 400 is used as a radiator of the antenna structure, and the signal of the antenna structure can be radiated through the radiation grooves 401 located at different positions of the decoration 400, so that the signal radiation effect of the antenna structure can be effectively improved.

Optionally, the at least two radiation slots 401 include a first radiation slot and a second radiation slot, and the first radiation slot and the second radiation slot have different opening orientations.

Referring to fig. 2, when the decoration 400 is a rectangular frame, the first radiation groove and the second radiation groove may be respectively provided with two adjacent sidewalls of the decoration 400. When the decoration 400 is a circular frame, the first radiation groove and the second radiation groove may be respectively formed at different positions along the outer circumferential direction of the decoration 400. Therefore, the opening orientations of the first radiation groove and the second radiation groove are different.

In this embodiment, the openings of the first radiation slot and the second radiation slot are respectively oriented in different directions, and the antenna transmits and receives signals with directivity, so that the first radiation slot and the second radiation slot can respectively radiate signals in different directions, or respectively receive signals in different directions, thereby further improving the radiation performance of the antenna structure.

Optionally, an insulating medium is disposed in a gap formed between the radiation slot 401 and the feeder 300.

In this embodiment, an insulating medium is disposed in a gap formed between the radiation slot 401 and the feeder 300, so that external particles can be prevented from entering the radiation slot 401 to affect the radiation performance of the antenna structure, and meanwhile, the radiation slot 401 is filled with the insulating medium, so that the flatness of the surface of the decoration 400 can be ensured.

Optionally, an electrical conductor 600 is disposed in the radiation slot 401, the electrical conductor 600 and the inner wall of the radiation slot 401 are disposed at intervals, and the feed source, the feed line 300, the decoration piece 400 and the electrical conductor 600 together form a dual-frequency antenna structure.

Wherein the electrical conductor 600 may be other components than the decoration 400, for example, the electrical conductor 600 may be a metal electrical conductor. Further, the conductor 600 may be formed by a protrusion on the surface of the decorative member 400, and for example, the conductor 600 may be a protrusion protruding inward of the radiation groove 401.

Specifically, by disposing the conductor 600 in the radiation slot 401 and spacing the conductor 600 from the inner wall of the radiation slot 401, when the antenna signal on one side of the conductor 600 is radiated to the other side of the conductor 600, the resonant frequency will change, and referring to fig. 5, a graph of the reflection coefficient of the antenna structure in the present embodiment is shown, and as can be seen from fig. 5, the resonant frequencies of the signals on both sides of the conductor 600 are different, so as to form a dual-frequency antenna. Thus, by adjusting the position of the conductor 600 in the radiation slot 401, the relative magnitude of the resonant frequency of the signals on both sides of the conductor 600 can be adjusted. Wherein the electrical conductor 600 may be placed close to the side where the resonance frequency is higher.

In this embodiment, the conductor 600 is disposed in the radiation slot 401 to form a dual-frequency antenna, so that the antenna structure can radiate in different frequency bands, thereby further improving the radiation performance of the antenna structure.

Optionally, the first circuit board 200 further includes a resonant circuit, the conductor 600 extends from the radiating slot 401 into the housing 100, and the conductor 600 is electrically connected to the resonant circuit to tune the resonant frequency of the antenna structure.

Specifically, a through hole is provided on a surface of the mounting board near one side of the housing 100, and the conductor 600 extends into the housing 100 through the through hole and is electrically connected to the resonant circuit.

The resonant circuit may be a common matching circuit, for example, a matching circuit that may be formed by an inductor and a capacitor together.

It should be appreciated that one end of the conductor 600 is electrically connected to the matching circuit, and the other end of the conductor 600 is electrically connected to the inner wall of the radiation slot 401, so that the resonant frequency of the antenna structure can be tuned by the resonant circuit and the conductor 600.

Alternatively, the electric conductor 600 is movably connected with the radiation groove 401, and the electric conductor 600 may be moved within the radiation groove 401 along a length direction of the radiation groove 401.

Specifically, a sliding groove may be formed on two opposite inner walls of the radiation groove 401, and two ends of the conductor 600 may be respectively embedded into the two sliding grooves, so that the conductor 600 may move along the sliding grooves in the radiation groove 401.

In this embodiment, since the positions of the conductor 600 in the radiation slot 401 are different, the resonant frequencies of the two sides of the conductor 600 will change, and in this embodiment, the conductor 600 is movably connected with the radiation slot 401, so that the resonant frequencies of the antenna structure can be tuned by controlling the conductor 600 relative to the radiation slot 401, thereby meeting different frequency requirements.

Optionally, the electronic device further includes a motherboard, and the first circuit board 200 is electrically connected to the motherboard;

Wherein, the first circuit board 200 and the main board may be electrically connected through an FPC or a connector.

Specifically, the first circuit board 200 may be a millimeter wave radio frequency front end circuit board. The first circuit board 200 may be attached to the decoration 400, for example, the first circuit board 200 may be stacked with the decoration 400, so that the distance between the millimeter wave antenna and the radio frequency front end may be effectively shortened, and the link loss of the millimeter wave radio frequency front end is reduced, thereby improving the efficiency of the antenna structure.

Alternatively, the dielectric constant of the first circuit board 200 may have a value ranging from 2 to 2.4, and the decoration 400 may be made of a dielectric material having a loss tangent angle of 0.0009.

In this embodiment, the range of the dielectric constant of the first circuit board 200 is set to be 2-2.4, so that the equivalent dielectric constant around the antenna structure can be ensured to be relatively fixed, and the antenna structure can be adapted to different types of terminals.
