Abstract

The invention discloses an antenna of a mobile terminal, a method and the mobile terminal. The antenna of the mobile terminal comprises an antenna end, a radio frequency input end, a matching networkand a controller, Wherein the matching network comprises a variable capacitor and / or an active device; And the controller is used for changing the parameter value corresponding to the variable capacitor and / or the active device when determining that the USB line is inserted into the USB interface of the mobile terminal, so that the impedance value of the matching network adapts to the insertion ofthe USB line. So visible, The embodiment of the invention provides an antenna of a mobile terminal. When a USB line is inserted into a USB interface of the mobile terminal, the USB line can be inserted into the USB interface; The impedance value of the matching network is changed by changing the capacitance value of the variable capacitor and / or the impedance value presented by the active device,so that the impedance value of the matching network adapts to the insertion of the USB line, and when the USB line is inserted into the USB interface of the mobile terminal, the good performance of the antenna is kept, and the good communication quality is provided.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to an antenna for a mobile terminal, a method and the mobile terminal. Background technique [0002] Currently, mobile terminals are more and more widely used, and receiving and sending signals by the mobile terminal depends on the antenna of the mobile terminal. Therefore, the performance of the antenna has a great influence on the communication quality of the mobile terminal. [0003] Taking a mobile phone as an example, the antenna on the mobile phone is used to receive or send signals, and the old mobile phone usually has a protruding antenna. But along with the development of science and technology, on the one hand, the function of mobile phone is more and more, for example, most mobile phones support utilizing USB interface to transmit data. On the other hand, users have higher and higher requirements on the appearance of mobile phones. In order to meet the ...
