Description

an electronic device

technical field

The present invention relates to the technical field of electronic devices, and in particular, to an electronic device.

Background technique

The fifth generation mobile communication technology (5G) can provide higher communication speed, lower latency and more simultaneous connections than previous generation technologies. Among them, because of its very wide communication bandwidth, millimeter-wave communication technology with a frequency band above 20GHz is one of the key technologies in 5G technology.

Due to the large propagation loss and reflection loss of millimeter-wave in space, the millimeter-wave communication technology standard in 5G technology stipulates that the millimeter-wave antenna should have a gain above a certain level to compensate for various losses in the space link. This requires that the millimeter-wave antenna is in the form of an antenna array, and the phased array beamforming is realized by controlling the phase difference between the neutron antennas in the array, so that the synthesized beam has a high gain.

Specifically, millimeter-wave antenna modules of electronic devices such as mobile phones are often installed under components such as back shells that use insulator plates such as glass or ceramics, and the dielectric constant of these insulator materials is greater than that of air. For ultra-high frequency electromagnetic waves, the wave impedance inside the plate is different from the wave impedance of the air. As a result, when the ultra-high frequency electromagnetic waves emitted by the millimeter-wave antenna installed below pass through these insulator plates, reflected waves and refracted waves will appear due to the mismatch of wave impedance, which will lead to antenna mismatch and loss. If it increases, on the other hand, the electromagnetic wave radiation direction will be disordered, and the radiation performance of the millimeter wave antenna will be weakened. In addition, when these back shells or side frames are designed to be metal, the electromagnetic waves radiated by the millimeter-wave antenna at the lower part will be reflected and lost, so the millimeter-wave antenna module cannot be installed in the lower part of the metal sheet shell. The space for installation is largely limited.

It can be seen from the above that the structure of the existing electronic device has a problem that affects the performance of the antenna.

In the embodiment of the present invention, the antenna module may specifically be a millimeter-wave antenna module, but it is not limited thereto.

The electronic device provided by the embodiment of the present invention is further described below, and the antenna module takes a millimeter wave antenna module as an example.

In view of the above technical problems, in order to solve the problem of the influence of the shell plate of electronic devices such as mobile phones on the performance of the millimeter-wave antenna below it, and considering that in general, the cover plate of the camera area of the electronic device (that is, the above-mentioned setting area) is in the material In terms of type selection and structural design, the degree of freedom is higher than that of the large-area shell plate of the whole machine, so the performance of the millimeter-wave antenna can be guaranteed to the greatest extent. Therefore, an electronic device is proposed, which involves installing the millimeter-wave antenna module on an electronic device. The solution for the camera area of the device; the solution provided by the embodiment of the present invention is illustrated below with an example.

Example 1

(1) The overall structure of Example 1 is shown in Figure 1. The structure of this example involves the housing cover of the electronic device (ie the electronic device cover), the camera area (ie the above-mentioned setting area 2), the camera area cover (ie the above-mentioned area cover 4), at least one camera module 1, At least one millimeter wave antenna module, a circuit board 7, and a connection line between each module and the circuit board.

(2) What is shown in FIG. 1 can also be understood as an external view of the electronic device, and the camera area is located at a certain position of the body of the electronic device.

(3) What is shown in FIG. 2 can also be understood as an internal view of the electronic device after the casing cover is removed. A camera module 1 and a millimeter-wave antenna module are located in the camera area, and the two types of modules are placed side by side without overlapping each other. The two types of modules can be connected to the circuit board of the electronic device through a flexible circuit board or other suitable means to transmit signals and feed power. Other components of the electronic device may also be placed in the camera area, which is not limited herein. 9 in FIG. 2 denotes a flexible circuit board and a connection port.

(4) What is shown in FIG. 3 can also be understood as a partial enlarged cross-sectional view of the camera area. The camera module 1 and the millimeter-wave antenna module are placed and installed in the vacancy of the circuit board (ie, the above-mentioned vacant area 8 ), or placed and installed on the circuit board 7 . The electronic device cover 10 in the camera area has a vacant part (refer to FIG. 3 , which is basically the same as the vacancy of the circuit board, that is, the vacant area 8 ), and the size of the vacant part can make the two types of modules directly above the module without cover. . The vacant part is covered and filled with a camera area cover plate. A decorative ring 11 may be connected between the camera area cover and the electronic device cover 10 to ensure sealing and appearance.

The camera area cover can be a non-metal or an insulator, and has a certain light transmittance in the area directly above the camera module. 9 in FIG. 3 denotes a flexible circuit board and a connection port.

In the solution of this example: since the cover plate of the camera area of the electronic device such as the mobile phone and the cover plate of the casing covering most of the electronic device are different parts, the degree of freedom in the selection of materials and structures can be increased according to the performance of the millimeter-wave antenna. Larger, easier to design to have as little impact on mmWave antenna performance as possible.

Other components of the electronic device may also be placed in the camera area, which is not limited herein. 9 in FIG. 5 denotes a flexible circuit board and a connection port.

(3) What is shown in FIG. 6 can also be understood as a partial enlarged cross-sectional view of the camera area. The camera module and the millimeter-wave antenna module are placed and installed in the vacancy of the circuit board (ie, the above-mentioned vacant area 8 ), or placed and installed on the circuit board 7 . The coupling components between the plurality of camera modules 1 are bypassed (specifically, not passing through the area where the millimeter-wave antenna module is located), or not covered (specifically, not passing through the top of the millimeter-wave antenna module (ie, the millimeter-wave antenna module). between the antenna module and the area cover), can pass under the millimeter-wave antenna module without affecting the antenna performance) the millimeter-wave antenna module. The electronic device cover 10 in the camera area has a vacant part (see FIG. 6 , which is basically the same as the vacancy of the circuit board, that is, the vacant area 8 ), and the size of the vacant part can make the two types of modules directly above the module without cover. . The vacant part is covered and filled with a camera area cover plate. A decorative ring 11 may be connected between the camera area cover and the electronic device cover 10 to ensure sealing and appearance. The lens 12 of the camera module 1 and the antenna 13 of the millimeter-wave antenna module face the camera area cover. The camera area cover can be a non-metal or an insulator, and has a certain light transmittance in the area directly above the camera module. 9 in FIG. 6 denotes a flexible circuit board and a connection port.

In addition to the advantages of the solution in Example 1, the solution in this example can also make the design of the camera module and the millimeter-wave antenna module more compact, saving the internal space of the electronic device.
