1. A transmitter for wireless power transmission, comprising;

  • at least two antennas for sending and receiving RF signals and sending RF power waves;

    a communication circuit for receiving RF signals representing status information from a chargeable electronic device including the location of the electronic device;

    a radio frequency integrated circuit connected to the antennas for processing the power RF waves;

    a microprocessor for controlling the radio frequency integrated circuit to generate and to control the shape of the RF power waves and for controlling the communication RF signals representing the status information from the chargeable electronic device;

    a source of power connected to the RF integrated circuit for generating at least two RF power waves with one of the two RF power waves being phase shifted and gain adjusted with respect to the other RF power wave by the microprocessor for generating constructive and destructive interference patterns of RF power waves to form pockets of energy from the constructive interference patterns of RF waves and to form null-space without pockets of energy;

    wherein the transmitter wirelessly broadcasts RF power waves that converge in 3-dimensional space to form pockets of energy in a 3-dimensional shape for reception by a receiving device for charging or powering the chargeable electronic device.
