As shown in fig. 1, fig. 1 is a schematic structural diagram of a mobile terminal according to an embodiment of the present disclosure. In fig. 1, a mobile terminal 10 according to an embodiment of the present disclosure includes a back plate 11, a camera module 13 protruding from the back plate 11, and an antenna 15 disposed inside a cover plate of the camera module 13; the antenna 15 includes a first coil 151 and a second coil 152, the first coil 151 is located on a first plane, and the second coil 152 is located on a second plane, where the first plane is parallel to the second plane. Referring to fig. 2, in the embodiment of the disclosure, the first plane may be an upper surface of the camera module 13 shown in fig. 2, and the second plane may be an inner side of the upper surface of the back plate 11. In addition, a cover plate may be further included above the camera module 13, and the first coil 151 may be disposed between the camera module 13 and the cover plate. Since the second coil 152 is disposed on the second plane, the second coil 152 is disposed on a side of the camera module 13 away from the cover plate. Referring to fig. 1 again, the second coil 152 is disposed around the camera module 13. In addition, the first coil 151 and the second coil 152 have a gap, such as an inverted L-shaped gap, in a direction parallel to the first plane and the second plane (i.e., a direction parallel to the paper surface of fig. 1), and the camera module 13 is disposed in the gap; and the second coil 152 is disposed around the first coil 151. And because the first coil 151 and the second coil 152 have a height difference in a direction perpendicular to the paper surface, the first coil 151 and the second coil 152 are connected to form a three-dimensional coil. The antenna 15 may include a near field communication/short range wireless communication antenna and a charging coil, such as a wireless charging coil, etc. In particular, the first coil 151 and the second coil 152 in the present embodiment are rectangular for illustrative purposes only, and other shapes may be used.

Wherein an outer side of the first edge meets an inner side of the fifth edge in a direction parallel to the page, an outer side of the second edge meets an inner side of the sixth edge in a direction parallel to the page, the third edge does not contact the seventh edge, and the fourth edge does not contact the eighth edge; in other words, there is a first gap between the third edge and the seventh edge and a second gap between the fourth edge and the eighth edge. Such an arrangement may leave sufficient space between the third edge and the seventh edge and between the fourth edge and the eighth edge for exposing a camera. Specifically, the camera module 13 is disposed corresponding to the first gap and the second gap, that is, the camera module 13 may be disposed at the first gap and the second gap.

The signal transmission direction is not limited to the clockwise direction, but may also be the counterclockwise direction, i.e. the signal transmission direction within the coil may also be opposite to the above. However, the first coil 151 and the second coil 152 transmit signals in the same direction, i.e., both clockwise and both counterclockwise. The other end of the second coil 152 may be connected to a communication module.

Referring to fig. 6 and 7, fig. 6 is a schematic structural diagram of an antenna according to another embodiment of the present disclosure, and fig. 7 is a schematic structural diagram of a mobile terminal according to another embodiment of the present disclosure. The antenna 15 of the embodiment of the present disclosure may further include a third coil 153 disposed around the second coil 152. The third coil 153 may be disposed in the same plane as the second coil 152. Similarly, the first coil 151, the second coil 152, and the third coil 153 are connected to form a stereoscopic coil. That is, compared to the above-mentioned embodiment, the antenna 15 in the present embodiment may further include more sets of coils, such as a fourth coil, a fifth coil, and the like. In fig. 6, the first coil 151 is located on the camera module 13 protruding from the plane of the back plate 11, the second coil 152 and the third coil 153 may be located inside the back plate 11, the third coil 153 is disposed around the second coil 152, the second coil 152 is disposed around the camera module 13 and connected to the first coil 151 located on the camera module 13, and a three-dimensional coil with a height difference is formed by coils wound layer by layer. The third coil 153 may be connected to the communication module, and the signal may be transmitted from the outside to the inside of the antenna 15, that is, the third coil 153 flows to the first coil 151 through the second coil 152 layer by layer. Of course, the signal transmission direction in the antenna 15 can also be reversed, i.e. from the first coil 151 to the third coil 153 via the second coil 152. The signal transmission direction in each coil is identical, i.e. both clockwise and both counter-clockwise.

In addition, in the embodiment of the present disclosure, the mobile terminal 10 further includes a display module (not shown); the display module and the back plate 11 are oppositely arranged to form an accommodating space; the circuit board can be arranged in the accommodating space. Specifically, the display module may be, for example, a display screen, and the circuit board may be provided with components such as a battery, a flat cable, various sensors, and a microphone.

In the embodiment of the disclosure, the coil can be specifically attached to the right above the decoration of the camera module, attached to the lower part of the glass mirror surface of the decoration and the outer surface of the decoration support frame. The wire may pass through the inside of the camera module assembly fixture and then be connected to a communication module on the circuit board, such as a near field communication chip terminal. The coil can be attached to the surface of the camera module assembly ornament, and if the area of the surface of the camera module assembly ornament is smaller, the winding of part of the coil can be expanded to the outside of the camera module assembly ornament, namely, the winding above the main board and the winding on the camera module assembly ornament form a three-dimensional antenna or a charging coil.

The embodiment of the disclosure provides that the coil is expanded to the camera module, so that not only can the space of a mobile terminal such as a mobile phone be fully utilized, but also the integrated design of the coil and the camera module can be realized.
