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. |
