| Abstract | PROBLEM TO BE SOLVED: To full-bridge-drive a plurality of antennas by a simple circuit configuration.SOLUTION: A half-bridge circuit HB0 is commonly provided for antennas ANT1 to ANT3, and an output terminal OUT0 is connected to one ends of the antennas ANT1 to ANT3. Half-bridge circuits HB1 to HB3 are individually provided for the antennas ANT1 to ANT3, and output terminals OUT1 to OUT3 are connected to the other ends of the antennas ANT1 to ANT3, respectively. A control unit 121 controls switching of the half-bridge circuits HB0 to HB3, and controls the supply of driving power to the antennas ANT1 to ANT3. The present invention is adaptable, for example, for a transmission device transmitting signals to a portable device for a vehicle. |
