PROBLEM TO BE SOLVED: To reduce a specific absorption rate (SAR).SOLUTION: Wireless WAN antennas 101, 103 mounted on a tablet terminal 10 are close to parts 153, 155 of a human body 151. Any one of the antennas 101, 103 functions as a transmission antenna in a communication mode. When the antenna 101 is a transmission antenna, the part 153 absorbs electromagnetic wave energy, whereas when the antenna 103 is a transmission antenna, the part 155 absorbs electromagnetic wave energy. The antennas 101, 103 are switched so that any one of them is a transmission antenna in a cycle within the evaluation time of the SAR. The parts 153, 155 are made to absorb half of the amount of the energy absorption before switching.SELECTED DRAWING: Figure 1 |
