Abstract

Embodiments of the present disclosure describe various techniques for integrating wireless power facilities or functionality into an existing object or device via embedded or deposited surface antennas. More specifically, the techniques described herein provide for the ability to embed and/or otherwise deposit spatially-arrayed adaptively-phased antennas on the surface of an existing object or device such that the antennas are exposed to air and/or otherwise lacking significant interference. In some embodiments, a wireless power control system is operatively coupled to the antennas to independently control phases of the phased of the antennas in a wireless power delivery environment.
