Therefore, the present application is not limited to the specific embodiments disclosed below.

[0047] Mobile devices such as mobile phones and tablets are arranged with a mainboard, antenna, and display module 500 through a frame. The antenna is used to enable the mobile device to communicate wirelessly with the outside world, and the display module 500 is used for display and touch operation.

[0048] Please refer to Figures 1 to 4 One embodiment provides an antenna structure for a mobile device, including a first antenna module, a second antenna module and a radio frequency module, wherein the first antenna module and the second antenna module are both electrically connected to the radio frequency module.

[0049] like Figure 2 and Figure 3 As shown, the first antenna module includes a first antenna array 110 , and the first antenna array 110 is used to be arranged on the light-emitting side of the display module 500 .

[0050] like Figure 3 and Figure 4 As shown, the second antenna module includes a second antenna array 210 , and the second antenna array 210 is used to be arranged between the first end of the display module 500 and the frame 420 of the mobile device.

[0052] For example, the first end is the bottom of the display module 500 , and there is a certain gap between the bottom of the display module 500 and the inner wall of the frame 420 for arranging the second antenna array 210 .

[0053] The RF module is electrically connected to both the first antenna array 110 and the second antenna array 210 .

[0054] The radio frequency module (not shown) includes a radio frequency circuit board and related circuits, such as circuits connected to the motherboard. The radio frequency module can be fixed to the frame 420 or integrated into the motherboard of the mobile device.

[0072] In one embodiment, please refer to Figure 3 and Figure 4 The flexible circuit board 220 further has a bending portion 223 , and the bending portion 223 is used to bend the flexible circuit board 220 to form a first plate body 221 .

[0073] like Figure 3 and Figure 4 From the perspective shown, the flexible circuit board 220 is bent downward in the opposite direction of the Z-axis direction to form a first plate body 221. The first plate body 221 is located between the first end of the display module 500 and the inner side of the frame 420. The second antenna array 210 is arranged on the first plate body 221.

[0074] like Figure 3 and Figure 4 As shown, at least one third antenna array 310 includes a bent antenna unit 311 . The bent antenna unit 311 is electrically connected to the flexible printed circuit board 220 , and at least a portion of the bent antenna unit 311 is located at the bent portion 223 .

[0076] It should be noted that: in order to show the layout of the antenna unit, Figure 4 The first antenna unit 111, the second antenna unit 211 and the bent antenna unit 311 are all suspended in the air, but are not actually suspended in the air, so they will not be described in detail.

[0077] like Figure 3 In the illustrated perspective, A1 in the first antenna array 110 , the meandering antenna unit 311 , and B1 in the second antenna array 210 form a third antenna array 310 .

[0078] In one embodiment, please refer to Figure 3 and Figure 4 The flexible circuit board 220 also has a second board 222, which is used to be arranged on the light-emitting side of the display module 500, and the bending portion 223 is located between the second board 222 and the first board 221, and at least one third antenna unit is arranged on the second board 222.

[0079] like Figure 3 and Figure 4 As shown, the flexible circuit board 220 forms a first plate body 221 and a second plate body 222 by setting the bending portion 223. The plane where the first plate body 221 is located is parallel to the plane where the display module 500 is located, and the plane where the second plate body 222 is located is perpendicular to the plane where the first plate body 221 is located.
