Abstract

Embodiments of the invention provide an antenna tuning structure of a mobile terminal and the mobile terminal. The antenna tuning structure of the mobile terminal comprises a substrate wherein the substrate is provided with an antenna, a USB assembly and a main grounding circuit; the antenna comprises an antenna controllable switch; the USB assembly comprises a USB socket and a USB grounding pin; the USB socket is electrically connected with one end of the USB grounding pin; the other end of the USB grounding pin is electrically connected with one end of the antenna controllable switch; and the other end of the antenna controllable switch is electrically connected with the main grounding circuit. The technical requirements of USB socket suspension and the anti-theft requirement of the USB socket in an exhibition room can be satisfied; meanwhile, the intelligent tuning of the antenna between a low-frequency band and a high-frequency band can be realized as well; when the antenna controllable switch is disconnected, the USB socket is suspended, so that the radiation environment of the antenna is improved, the Q value in the antenna radiation is lowered, and the radiation efficiency of the antenna is improved; and when the antenna controllable switch is closed, the USB grounding pin and the main grounding circuit are connected so as to satisfy the anti-theft technical requirement of the USB socket in the exhibition room.

Description

【Technical field】 [0001] The present invention relates to the technical field of mobile communication, in particular to an antenna tuning structure of a mobile terminal and the mobile terminal. 【Background technique】 [0002] With the continuous development of technology, people use mobile terminals such as mobile phones more and more widely in their daily life. The antenna in the mobile terminal plays a vital role in the communication of the mobile terminal. Due to the widespread use of metals in mobile terminals, the tuning and performance of antennas face great challenges. [0003] The antenna tuning structure of the mobile terminal is to control the state of the controllable switch of the antenna through the voltage, thereby indirectly changing the matching or electrical length of the antenna, so as to achieve the radiation frequency required by the intelligent control antenna. figure 1 It is a schematic diagram of an antenna tuning structure of a mobile terminal in th...
