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.
