Abstract
Wireless power transfer systems and methods for focusing wireless power transfer arrays are disclosed. One embodiment includes a wireless power generating unit (GU) including a processing system configured to focus the RF power sources by: sending control signals to the control circuitry to perform a plurality of sweeps using each of a plurality of different basis masks; receiving a message from a RU containing a report based upon received power measurements made by the RU; and sending control signals to focus the RF power sources based on the received message from the RU. Furthermore, each sweep includes performing a phase sweep across a phase sweep range at a plurality of phase step increments with respect to a first group of RF power sources identified in a basis mask, where the first group of RF power sources comprises a plurality of RF power sources.
