Embodiment Construction

[0024] In order to describe the technical content, structural features, objectives and effects of the present invention in detail, the specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways than those described here, so the present invention is not limited by the specific embodiments disclosed below.

[0025] In order to solve the aforementioned technical problems, the existing mobile terminal antennas use reconfigurable technology to increase the bandwidth of the antenna. Generally, a radio frequency switch device is added at the feed end of the antenna to switch between different matchings, so as to realize multi-band and multi-mode operation; or, Use reconfigurable technology to switch the location of the ground point of t...

Abstract

Antenna system comprises an antenna module and a radio frequency signal processing circuit. The antenna module comprises a first access point and a second access point. The antenna system also comprises a switching device for achieving respective connection of the first and second access points of the antenna module with the radio frequency signal processing circuit and a reference ground. The invention achieves switching between feeding points of the antenna module and grounding points in different cases by using the switching device; and produces two different antenna radiation mechanisms by using the same antenna module pattern and therefore can make full use of the radiation characteristics of the same antenna to produce different resonance and increase the bandwidth. In this way, the complexity of the antenna module pattern can be reduced, the wiring area of the antenna is narrowed, and the current trend of miniaturizing a terminal product is met.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an antenna system, a mobile terminal with the antenna system, and a communication method for the mobile terminal. Background technique [0002] Today's wireless communication field is developing rapidly, terminal products are becoming more and more diverse, and the functions of terminal products are also becoming more and more abundant. In addition to simple call functions, it also includes functions such as wireless Internet access, video calls, Bluetooth data transmission, GPS positioning and navigation, and NFC (Near Field Communication) fast payment. The antenna is an indispensable part of the communication system, and the excellent performance of the antenna directly determines the system performance of the entire mobile terminal. Therefore, the multifunctionalization of mobile terminals will inevitably increase the number of antennas of terminal products. [0003] On t...
