Abstract
An RF power delivery system includes, in part, an N×M array of transmitting elements disposed along N rows and M columns where M an N are integer numbers, and a phase adjustment unit adapted to receive information representative of a change in position of a device targeted to receive the RF power wirelessly from the device and generate a codeword in response, and apply the codeword to adjust phases of the array of transmitting elements.
