1. A wireless microwave power transmitter comprising:

  • a controller and a phased array antenna having at least one microwave array transceiver for transmitting a microwave power transmission signal, the transceiver being adaptively-phased by the controller to transmit the power transmission signal at a first phase;

    the transceiver further operable to receive a calibration signal from a device to be charged and detect a second phase at which the calibration signal is received by the receiver;

    the controller further configured to adjust the first phase for use in transmitting the power transmission signal to be the same as the second phase wherein the second phase indicates whether an optimal phase for the power transmission signal to be transmitted to the device to be charged; and

    wherein the power transmission signal is transmitted without receiving a location signal from the device to be charged that indicates the location of the device to be charged.
