BEAMFORMING METHOD FOR MICROWAVE POWER TRANSFER AND MICROWAVE TRANSMITTER FOR POWER TRANSFER BASED ON BEAMFORMING

摘要

A beamforming method for microwave power transfer comprises the following steps: a transmitter transmits a microwave through a plurality of antennas with a random phase for each training slot; the transmitter receives a receiving power measurement value on each of the training slots from a receiver; the transmitter estimates a channel by using only the receiving power measurement value; and the transmitter determines a beamforming weighted value by using information on the estimated channel.
