Abstract

The invention provides an antenna of a mobile terminal and the mobile terminal. The antenna of the mobile terminal comprises an antenna radiation body, a first adjustment circuit and a feeding source, wherein the antenna radiation body is fixed on the mobile terminal, the first adjustment circuit is used for adjusting a working frequency of the antenna radiation body, one end of the first adjustment circuit is electrically connected with the antenna radiation body, the other end of the first adjustment circuit is electrically connected with a main floor of the mobile terminal, one end of the feeding source is electrically connected with the antenna radiation body, and the other end of the feeding source is electrically connected with the main floor. According to the scheme, the antenna works in different frequency ranges by controlling the first adjustment circuit to be in different states, so that the problem of difficulty in debugging the antenna covering low-frequency, intermediate-frequency and high-frequency bands is solved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an antenna for a mobile terminal and the mobile terminal. Background technique [0002] Mobile terminal antenna Multi-frequency broadband has always been the development direction of mobile communication, especially portable mobile terminals, such as mobile phones, the low-frequency bandwidth is 824Mhz-960Mhz, the intermediate frequency bandwidth is 1710Mhz-2170Mhz, and the high-frequency bandwidth is 2300-2690Mhz. In addition, due to the complexity of functions such as mobile phone terminals, the space for mobile phone antennas is getting smaller and smaller. Among them, the antenna area has speakers, USB, fingerprint modules, earphones, etc. These devices make the antenna more and more affected. Under this premise, it is very difficult to debug an antenna that can cover LF, MF and HF bands. Contents of the invention [0003] Embodiments of the present invention ...
