    • PURPOSE: A mobile communication terminal is provided to regularly maintain transmitting and receiving performance of an electric wave in wireless charging by selectively operating an antenna in wireless charging with a switching operation. CONSTITUTION: A sensor detects whether a terminal is arranged in a charging pad or not. A first antenna(210) generally operates the terminal in a use mode. A second antenna(220) operates the terminal in a charging mode. A switch(230) selectively operates the first or second antenna with a switching operation according to the sensing result of the sensor. A rectifying part(250) changes a direct current voltage, rectified with an induced electromotive force, into a standard voltage.
    • 目的:提供一种移动通信终端,通过在切换操作中选择性地操作无线充电中的天线,定期维持无线充电中的电波发射和接收性能。 构成:传感器检测终端是否安装在充电垫中。 第一天线(210)通常以使用模式操作终端。 第二天线(220)以充电模式操作终端。 开关(230)根据传感器的感测结果用切换操作选择性地操作第一或第二天线。 整流部(250)将以感应电动势整流的直流电压变更为标准电压。
