Abstract

The invention provides a mobile communication terminal common antenna circuit. The mobile communication terminal common antenna circuit comprises a common antenna, a combiner connected with the common antenna through an antenna impedance matching circuit, at least two radiofrequency systems connected with the combiner and comprising a mobile signal radiofrequency system and a GPS radiofrequency system, and a radiofrequency transmitting-receiving unit connected with the mobile signal radiofrequency system and the GPS radiofrequency system. In the mobile communication terminal common antenna circuit, the at least two radiofrequency systems are combined and then are connected with the common antenna so as to share the common antenna. Shared, the common antenna occupies little space so that convenience is given to the structural and shape design of the mobile communication terminal.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a common antenna circuit for mobile communication terminals. Background technique [0002] There are many radio frequency systems in the current mobile communication terminals, such as mobile communication networks (eg: GSM, WCDMA, CDMA, TD-SCDMA, LTE, etc.), Bluetooth, WI-FI, GPS, FM, etc., these radio frequency systems need to use antennas . Therefore, in existing mobile communication terminals, there are many antennas, and GPS, WI-FI, and Bluetooth all use independent antennas. Due to the large number of antennas, the antennas need to occupy a large space, which brings difficulties to the structure and shape design of mobile communication terminals, is not conducive to the structure and shape design of mobile communication terminals, and does not conform to the current trend of thinner and lighter mobile communication terminals.
