WIRELESS COMMUNICATION DEVICE

A wireless communication device of the disclosure includes: an antenna, in response to receiving a radio wave, transmitting a radio frequency signal corresponding to the radio wave; a detector, detecting the radio frequency signal to obtain a detection signal; a circuit part, performing signal processing based on reception data obtained by performing demodulation processing on the detection signal; a regulator, in response to receiving an external power source voltage from an external source, generating and supplying an internal power source voltage for operating the circuit part to the circuit part; and a radio wave detection control part, detecting whether or not the antenna is receiving a radio wave and stopping a generation operation of the internal power source voltage by the regulator in response to the antenna not receiving the radio wave.
