Antenna device and mobile terminal

Abstract

The embodiment of the invention discloses an antenna device and a mobile terminal. The antenna device disclosed by the embodiment of the invention comprises an antenna support, a camera and metal parts with openings, wherein a plurality of antennas are disposed on the antenna support, and the antennas are connected to corresponding antenna feed points on a mobile terminal mainboard; the metal part is disposed on the antenna support and located between the two adjacent antennas; the camera is disposed under the metal part; and the metal part is equipped with a signal transmission terminal and the signal transmission terminal is grounded. The antenna device and the mobile terminal disclosed by the embodiment of the invention are grounded by the signal transmission terminal on the metal part and can release static electricity on the device. Meanwhile, a good isolation degree is formed between two electric wires adjacent to the metal part because of the metal part grounding.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an antenna device and a mobile terminal. Background technique [0002] With the vigorous development of wireless communication technology, especially the further intensification of competition in the smart phone industry, the proportion of ultra-thin and metal elements in the design of the whole machine is increasing, and mobile phones and other products are moving towards the direction of thinner, lighter and stronger metal texture. develop. [0003] However, due to the focal length requirements of the imaging of the rear camera, it cannot be as thin as the other parts of the whole machine and is relatively protruding, which makes the structural strength of the camera poor. On the other hand, it will also affect the appearance effect. Therefore, by introducing metal However, at the same time, the introduction of metal parts will deteriorate the performance of the ante...

Problems solved by technology

[0003] However, due to the focal length requirements of the imaging of the rear camera, it cannot be as thin as the other parts of the whole machine and is relatively protruding, which makes the structural strength of the camera poor. On the other hand, it will also affect the appearance effect. Therefore, by introducing metal However, at the same time, the introduction of metal parts will deteriorate the performance of the antenna, and it will also cause electrostatic risks in such a convex part of the camera; the antenna interface is very sensitive to electrostatic discharge, and if the protection is not good, it may cause internal radio frequency The device is permanently damaged, and the mobile phone will not be able to transmit signals through electromagnetic waves, which will eventually affect the communication quality of the system

[0004] In addition, in order to support more wireless functions, current smartphones often increase the number of mobile phone antennas, resulting in poor isolation between antennas and mutual interference between antennas, which will also affect communication quality and poor user experience.

[0005] From the above, there are technical problems in the prior art that static electricity cannot be released due to the introduction of metal parts, and the isolation between the secondary antennas is poor
