Abstract

The invention relates to a tunable antenna structure for a completely closed metal-frame mobile phone. An LTE main antenna feed point is arranged between a PCB and one side of a metal frame; an LTE diversity antenna feed point is arranged between the PCB and one side opposite to the LTE main antenna feed point; a GPS/WiFi feed point, a first frame ground point and a fourth frame ground point are arranged between the PCB and the other side; the first frame ground point and the fourth frame ground point are located at two sides of the GPS/WiFi feed point; a second frame ground point and a third frame ground point are arranged between the PCB and one side opposite to the GPS/WiFi feed point; a tunable device is arranged on the PCB and is connected with the second frame ground point; an LTE antenna is directly connected with a GPS/WiFi antenna through the feed point and the metal frame for feeding; and the metal frame is grounded through the ground points to form an antenna closed loop and to generate antenna resonance. The tunable device tunes low-frequency bandwidth and meets LTE full-band coverage.

Description

technical field [0001] The invention relates to an adjustable antenna structure for a mobile phone with a fully closed metal frame, and belongs to the technical field of antennas. Background technique [0002] With the continuous development of communication technology, mobile phones have become an indispensable communication tool for people, especially smart phones, which have far surpassed traditional feature phones and occupied the mainstream of the market. Compared with feature phones, smart phones have richer functions and more powerful performance, but this often needs to be at the expense of sacrificing the design space of the antenna. Especially in recent years, represented by Apple, HTC, and Huawei, mobile phones with metal shells and metal frames have gradually occupied the mainstream of the market. The emergence of mobile phones with metal shells and metal frames has broken the traditional antenna design ideas and greatly increased the difficulty of antenna desig...
