Abstract
A wireless power supply apparatus includes a controller, a beamforming module, and an antenna array. When direction finding information is obtained, the controller determines an electromagnetic wave transmission direction, and transmits information about the transmission direction to the beamforming module. The beamforming module aggregates energy of electromagnetic waves corresponding to a plurality of radio frequency signals to the transmission direction. The antenna array receives the direction finding information, and transmits the electromagnetic waves.
