<P>PROBLEM TO BE SOLVED: To perform communication using a radio wave of a plurality of frequency bands with the provision of a plurality of antenna elements, avoiding a large manufacturing cost increase and a large scale of a device with a suppressed influence of a human body. <P>SOLUTION: Information signal indicative of whether a human body touches a mobile terminal device 100 is obtained from a sensor unit 130. On the basis of the information signal, the connection of switches 105, 106, 121, and 122 is controlled. By the connection control of the switches 105, 106, 121, and 122, it is set whether transmission and reception are performed using two antennas including an antenna constituted by antenna elements 101, 102, and 103, the switch 105, and the switch 106 and an antenna constituted by an antenna element 104, or using two antennas including an antenna constituted by the antenna elements 101, 102, and 104, the switch 105, and the switch 106 and an antenna constituted by the antenna element 103. <P>COPYRIGHT: (C)2013,JPO&INPIT |
