Abstract

The invention discloses an antenna switching system of a mobile terminal. The antenna switching system comprises a first antenna, a second antenna, at least one duplexer and a switching unit, wherein the first antenna is arranged on the top of the mobile terminal and is used for transmitting and receiving GPS (Global Positioning System), WIFI (Wireless Fidelity) and BT (Bluetooth) signals, and GSM (Global System for Mobile Communications), WCDMA (Wideband Code Division Multiple Access) and TD-SCDMA (Time Division-Synchronization Code Division Multiple Access) signals of at least a first frequency band; the second antenna is arranged on the bottom of the mobile terminal and is used for transmitting and receiving GSM, WCDMA and TD-SCDMA signals of at least a second frequency band; the duplexer is coupled with the first antenna and is used for separating one or more of the GPS, WIFI, BT, GSM, WCDMA and TD-SCDMA signals; the switching unit is used for selecting the first antenna or the second antenna to work. With the adoption of the manner of the antenna switching system, the influences on the performance of the second antenna when a human body is contacted with the bottom of the mobile terminal are avoided, and user experiences are improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an antenna switching system for a mobile terminal. Background technique [0002] Mobile terminals, such as mobile phones, have been widely used by people as the most convenient means of contact. Since 2010, in order to obtain a better appearance design of mobile terminals, more and more manufacturers use metal frames as the main antenna and auxiliary antenna. Among them, the main antenna is set at the bottom of the mobile terminal to transmit and receive signals (referred to as GSM signals) and wideband code division multiple access (WCDMA) signals provided by the Global System for Mobile Communications (GSM). , WCDMA) signals and Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) signals, the secondary antenna is set on the top of the mobile terminal to transmit and receive Wireless Fidelity (WIFI) signals , Bluetooth (BT) signals, and signals ge...
