Abstract

The invention provides an antenna multiplex device, which comprises a compatible antenna, an antenna match circuit, an adjusting unit, a radio frequency transceiver module, a universal mobile telecommunication system (UMTS) transceiver and a controller. The compatible antenna is electrically connected with the radio frequency transceiver module and the UMTS transceiver through the antenna match circuit so as to receive the diversity signal of the UMTS or receive and transmit a radio frequency signal. The adjusting unit is electrically connected with the antenna match circuit. The controller controls working states of the UMTS transceiver and the adjusting unit according to the working state of the radio frequency transceiver module. The adjusting unit is used for slightly adjusting the resonance frequency of the compatible antenna, so that the compatible antenna can be reused for diversity reception of the UMTS and radio frequency receiving and transmitting. The antenna multiplex device fully uses idle time of the compatible antenna to realize the diversity reception function of the UMTS, thereby improving the use ratio of the cellphone memory.

Description

technical field [0001] The invention relates to a mobile communication device, in particular to an antenna multiplexing device. Background technique [0002] With the popularization of Universal Mobile Telecommunications System (UMTS) 3G mobile communication technology, the transmission rate of mobile phone uplink and downlink data services has been greatly improved, but high-speed data transmission is easily affected by multipath fading However, downlink data throughput is degraded. Therefore, a UMTS diversity (UMTS Diversity) antenna capable of overcoming multipath fading is required to assist the main antenna to improve the performance of high-speed data transmission. [0003] In order to achieve an ideal anti-multipath fading reception effect, the UMTS diversity antenna needs to realize space diversity with the main antenna, that is, the UMTS diversity antenna needs to be as far away from the main antenna as possible. Usually, the main antenna is set on the lower part o...
