PROBLEM TO BE SOLVED: To provide a mobile communication terminal that has a small loss, when one antenna system reaches a selection state, that does not need to make disconnection and its connection of the antenna system, in a measurement mode and short-circuits a termination circuit of an antenna system that is not selected. SOLUTION: In the measurement mode for a performance test of a wireless unit body, an open command is given respectively to switches SW1, SW4, SW5, SW8; and a closing command is given respectively to switches SW2, SW3, SW6, SW7, in the case of a mode of selecting an antenna ANT1; an open command is given respectively to the switches SW2, SW3, SW5, SW8; a closing command is given respectively to the switches SW1, SW4, SW6, SW7; in the case of selecting an antenna ANT2, an open command is given respectively to the switches SW1, SW4, SW6, SW7; and a closing command is given respectively to the switches SW2, SW3, SW5, SW8. |
