[0030] See also Figures 2 to 4, the antenna structure of the embodiment of the present disclosure includes a radiator 2 and a grounding body 3, and the antenna structure is arranged on the inner wall surface of the shell 13. Among them, the radiator 2 is at least partially arranged on the first inner wall surface 131 of the shell 13, and the first inner wall surface 131 and the plane where the display surface of the display screen 14 is located meet the vertical condition. The difference between the angle between the first inner wall surface 131 and the plane where the display surface of the display screen 14 is located and 90° is within the first threshold range, and the first inner wall surface 131 and the plane where the display surface of the display screen 14 is located meet the vertical condition. The first threshold can be, for example, 5°, 8°, 10°, 15°, 20°, 30°, etc. In a specific implementation, the angle between the first inner wall surface 131 and the plane where the display surface of the display screen 14 is located can be 60°, 90°, 120°, etc.

[0031] The grounding body 3 is disposed on the second inner wall surface 132 of the housing 13, the grounding body 3 is connected to the radiator 2, the grounding body 3 is used to ground the radiator 2, the second inner wall surface 132 is connected to the first inner wall surface 131, and the second inner wall surface 132 and the plane where the display surface of the display screen 14 is located meet the parallel condition. The angle between the second inner wall surface 132 and the plane where the display surface of the display screen 14 is located is less than the second threshold, and the second inner wall surface 132 and the plane where the display surface of the display screen 14 is located meet the parallel condition. The second threshold can be, for example, 5°, 8°, 10°, 15°, 20°, etc.

[0032] The first inner wall surface 131 is connected to the second inner wall surface 132, and there is a certain angle between the two. The first inner wall surface 131 and the second inner wall surface 132 are respectively located at different positions of the housing 13. The first inner wall surface 131 can be the inner surface of the side wall of the housing 13. The second inner wall surface 132 can be the inner surface of the side where the display surface of the housing 13 is located, or the inner surface of the side of the housing 13 opposite to the display surface.

[0033] In the antenna structure disclosed in the present invention, the radiator 2 is at least partially arranged on the first inner wall surface 131 of the housing 13 of the electronic device 1, and the first inner wall surface 131 and the plane where the display surface of the display screen 14 is located meet the vertical condition; the grounding body 3 connected to the radiator 2 is arranged on the second inner wall surface 132 of the housing 13, the second inner wall surface 132 is connected to the first inner wall surface 131, and the second inner wall surface 132 and the plane where the display surface of the display screen 14 is located meet the parallel condition, and the grounding body 3 is used for grounding the radiator 2.

The radiator 2 of the antenna structure is at least partially arranged on the first inner wall surface 131, and the rest of the grounding body 3 and the like are arranged on the second inner wall surface 132, making full use of the internal environment of the electronic device 1, but not being affected by the environmental space, improving the space utilization of the electronic device 1 while ensuring the antenna performance. Placing the antenna structure on different inner wall surfaces of the housing 13 of the electronic device 1 can improve the directivity of the 2.4G antenna radiation compared to placing it on a single inner wall surface, without changing the directivity of the 5G radiation, and has a positive effect on the reception of wireless signals.

[0035] In one embodiment, see Figure 1 The electronic device 1 also includes a second body 12, the second body 12 is connected to the first body 11 through a hinge, and the antenna structure is arranged at an end of the first body 11 away from the hinge.

[0037] The disclosed embodiment makes full use of the two adjacent inner wall surfaces of the shell 13 and sets the radiator 2 of the antenna at least partially on the first inner wall surface 131.

[0038] In one embodiment, the radiator 2 is formed on the first inner wall surface 131 by laser direct structuring (LDS).

The antenna structure is formed by laser direct structuring technology, and there is no need to change the mold when changing the antenna pattern, which is suitable for the production of different types of antennas. Laser direct structuring technology is directly laser engraved on the shell 13, which not only avoids internal metal interference of the device, but also reduces the size of the antenna.

The position of the feeding point 4 has a great influence on the matching and resonance point. When debugging the antenna structure, the low-frequency band can be debugged first, and then the high-frequency band can be adjusted.

[0042] In one embodiment, a wiring structure is provided on the second inner wall surface 132, and the wiring structure is used to fix the feeder. The wiring structure includes one or both of a wire trough and a wire clip. Of course, other forms of wiring structures can also be used in specific implementations.

The side wall of the housing 13 may be located on the first housing 13 or on the second housing 13. When the side wall is located on the first housing 13, the antenna structure is disposed on the first housing 13, and when the side wall is located on the second housing 13, the antenna structure is disposed on the second housing 13.

[0044] In one embodiment, an elastic conductor is provided on the grounding body 3. In a specific implementation, the elastic conductor can be a conductive foam. The grounding body 3 can be fully connected to the reference ground of the mainboard of the electronic device 1 through the elastic conductor. The grounding body 3 can be specifically made of copper foil. The grounding body 3 and the radiator 2 can be connected by welding or other appropriate methods.

[0046] Figure 6 The efficiency test curve of the antenna structure of the embodiment of the present disclosure is shown in FIG. As can be seen from the figure, the antenna efficiency is greater than -5dB in each frequency band, and the antenna indicators all meet practical requirements.

[0047] Figure 7 The figure shows a comparison of the 2.4GHz directional pattern of the antenna structure of the embodiment of the present disclosure and the antenna structure of the comparative example. The antenna designs of the embodiment and the comparative example are the same. In the embodiment of the present disclosure, the antenna is placed on the first inner wall surface and the second inner wall surface, and the antenna of the comparative example is placed on the second inner wall surface.
