Method of adjusting working frequency of antenna radiation body and corresponding mobile terminal

Abstract

The invention provides a method of adjusting a working frequency of an antenna radiation body. The method comprises the following steps that A, a mobile terminal acquires a network signal emitted by a base station, a working form and a working frequency of the mobile terminal are determined, and the mobile terminal comprises the antenna radiation body and a support of the antenna radiation body; and B, according to the working form and the working frequency of the mobile terminal, a dielectric constant of the support is changed so that a center working frequency of the antenna radiation body maintains consistent with the working frequency of the mobile terminal. A material of the support comprises quantum paraelectrics and / or a multiferroic material. Through applying an electric field, a magnetic field or a force, the dielectric constant of the support is changed so that the working frequency of the antenna radiation body is changed and the working form and the working frequency of the antenna radiation body are adjusted. The mobile terminal can carry out working frequency adjusting on the antenna radiation body according to the needed working form and the working frequency and a needed frequency range can be supported. Correspondingly, the invention also provides the mobile terminal capable of adjusting the working frequency of the antenna radiation body.

Problems solved by technology

[0003] The antenna radiator of the mobile terminal in the industry is fixed on a conventional structural member (bracket) by fixing a metal material of a certain shape. The antenna radiator and the bracket radiate energy at a fixed frequency as a whole. The excellent radiation performance of the mobile terminal and It depends entirely on the performance of the antenna engineer to debug the antenna radiator on the existing structure, resulting in poor performance of the antenna radiator of some models of mobile terminals

On the other hand, due to the increasing size of mobile terminal screens and batteries, the thickness of the whole machine is gradually thinning, leaving a very poor environment for the antenna space, and with the development of new technologies, the number of radio frequency bands supported by mobile terminals is increasing. As more and more antenna radiators need to support a sharp increase in the frequency range, in this case, the existing antenna radiator technology in the industry has become increasingly unable to fully meet the needs of mobile terminals
