Systems And Methods Of Estimating Optimal Phases To Use For Individual Antennas In An Antenna Array

摘要

A method includes receiving a wireless communication signal indicating that a receiver is within a wireless-power-transmission range of a transmitter. In response to the receiving, the method further includes transmitting a plurality of radio frequency (RF) test signals using at least two test phases for a respective antenna. The method further includes receiving information identifying a first amount of power delivered to the receiver by a first RF test signal transmitted at a first of the at least two test phases, receiving information identifying a second amount of power delivered to the receiver by a second RF test signal transmitted at a second of the at least two test phases, and determining, based on the first and second amounts of power, an optimal phase for the respective antenna.
