Abstract
Wireless power may be transferred using wireless power elements such as coil antennas for inductive wireless power transfer technology or patch antennas for capacitive wireless power transfer technology. These antennas in source equipment may couple in a near-field region to antennas implemented in target equipment. Wireless power may also be transferred from the source equipment to the target equipment using radiating antennas in their far-field regions. Wireless power transfer may be optimized by performing channel estimation operations. Foreign objects can be detected and located using sensors or by analyzing the quality of wireless channels. Optimum power transfer settings may be used to maximize wireless power transfer to a set of the antennas in the target equipment while minimizing power transfer to the foreign object.
