Abstract

The invention provides a GPS (Global Positioning System) and 3G (3rd-Generation) single-antenna realizing device which comprises a dual-resonant antenna used for receiving a radio frequency signal, a matching circuit which is connected with the dual-resonant antenna for obtaining the radio frequency signal and is used for performing signal matching processing on the radio frequency signal, and a diplexer, wherein the diplexer is connected with the matching circuit and is used for obtaining the radio frequency signal subjected to signal matching processing and sending the radio frequency signal subjected to separation processing respectively to a GPS module and a 3G diversity receiving module. The invention also provides a mobile terminal. Through the mode, according to the technical scheme disclosed by the invention, a GPS and 3G shared single antenna is realized by arranging the dual-resonant antenna, the matching circuit and the diplexer, so as to receive the signal; reflection loss and mismatch loss in the transmission process of the radio frequency signal are reduced; the transmission efficiency of the radio frequency signal is increased; the communication quality of the mobile terminal is enhanced; and the space of placing the antenna is not increased.

Description

technical field [0001] The invention relates to the field of mobile phone antennas, in particular to a mobile terminal and a GPS and 3G single-antenna realization device. Background technique [0002] With the rapid development of mobile communication technology, the current 2G (second generation) mobile communication network is quite popular and covers a wide range. Due to technical reasons, 2G mobile communication network has encountered unprecedented obstacles in the development process. In order to solve these problems, the 3G (third generation) mobile communication network began to develop, but because the 3G mobile communication network has just started, the coverage area is small, and the 2G mobile communication network cannot be upgraded to the 3G mobile communication network immediately, so the 2G mobile communication network appeared. The situation of coexistence with 3G mobile communication network. [0003] Therefore, the mobile terminal needs to integrate mult...
