GENERATOR UNIT FOR WIRELESS POWER TRANSFER
First Claim
1. An RF signal generator adapted to wirelessly transfer power to a first wireless device, said RF signal generator comprising:
- a first plurality of generating elements each adapted to generate an RF signal, the plurality of the RF signals being transmitted by a first plurality of antennas;
a wireless signal receiver; and
a control unit adapted to control a phase of the RF signal generated by each of the first plurality of RF signal generating elements in accordance with a first signal the receiver receives from the first wireless device, said first signal comprising information representative of an amount of RF power the first wireless device receives.

Abstract
An RF signal generator wirelessly transferring power to a wireless device includes, in part, a multitude of generating elements generating a multitude of RF signals transmitted by a multitude of antennas, a wireless signal receiver, and a control unit controlling the phases and/or amplitudes of the RF signals in accordance with a signal received by the receiver. The signal received by the receiver includes, in part, information representative of the amount of RF power the first wireless device receives. The RF signal generator further includes, in part, a detector detecting an RF signal caused by scattering or reflection of the RF signal transmitted by the antennas. The control unit further controls the phase and/or amplitude of the RF signals in accordance with the signal detected by the detector.
