Abstract: Disclosed is a transmitter used for a wireless charging system. The transmitter includes a plurality of phase locked loops (PLLs) that outputs single-phase power signals, a plurality of antennas that transmits power signals transmitted from the plurality of PLLs to a receiver, and a controller that determines a specific frequency for the receiver based on a signal strength indication (RSSI) received from the receiver and allows output frequencies of the plurality of PLLs to be different from each other in a specific frequency band preset based on the specific frequency.
