Abstract

The invention provides a multi-antenna wireless transceiving device which belongs to the technical field of communications and is suitable for a mobile communication terminal. The multi-antenna wireless transceiving device comprises a baseband chip, a radio frequency transceiver, a power amplification module, a matching network, an antenna selection switch and two or more antennae, wherein wireless transceiving performance indexes of the two or more antennae respectively correspond to different application modules of the mobile communication terminal; and the antenna selection switch is used for selecting one antenna from the two or antennae and controlling the selected antenna to be communicated with the matching network. By adopting the technical schemes, the invention enables that wireless performances of the mobile communication terminal are all optimized under various application environments, improves the customer satisfaction degree and is good for optimizing the mobile networkand improving the network capacity.

Description

Technical field [0001] The invention belongs to the field of communication technology, and particularly relates to a multi-antenna wireless transceiver device. Background technique [0002] Existing mobile communication terminals mostly use built-in antennas, and the application environment of built-in antennas has become more and more severe, mainly reflected in the following aspects: [0003] 1. Dual-mode and even multi-mode mobile communication terminals have become more and more popular, typically 3G and GSM dual-mode mobile communication terminals. This requires antennas to work in multiple frequency bands, only the GSM standard, mobile communication terminals have been required to start supporting up to Quad-band (supporting GSM850 / EGSM / DCS / PCS 4 GSM frequency bands at the same time), which is a multi-frequency and broadband antenna. The requirements are very high. [0004] 2. Mobile communication terminals are increasingly pursuing miniaturization, which requires a thin and ...
