Abstract
A method of generating a DC power from incident RF waves, includes, in part, measuring the amount of power being received by a device generating the DC power, and controlling the phases of the RF waves being transmitted by a multitude of RF transmitters in accordance with the measured power. A programmable test load is optionally used at the device to measure the received power. The device optionally includes, an antenna, an RF-to-DC converter to generate the DC power, an impedance matching/transformation circuit, and an RF load/matching circuit.
