Large area wireless power via a planar array of coupled resonators

Abstract

A method of enabling efficient wireless power delivery for a mobile receiver in a 3-D space is proposed. A reconfigurable planar array of coupled resonator (relay) coils is designed, and a method of choosing the optimal array configuration for a particular receiver position is proposed. Experimental results are obtained with a PCB implementation of the proposed planar relay array system operating near 13.56 MHz. Coverage improvements over conventional planar relay arrays are demonstrated.
