1. A transmitting device for transmitting wireless power to different locations of receiving devices, the transmitting device comprising:

  • a controller;

    an antenna array that includes;

    first antennas of a first type that are coupled to the controller; and

    second antennas, distinct from the first antennas, of a second type that are coupled to the controller,wherein the controller is configured to;

    when a first receiving device is detected at a first location, cause the first antennas to transmit a first set of power waves via the first antennas to generate a first constructive interference pattern at the first location of the first receiving device; and

    when a second receiving device is detected at a second location, distinct from the first location, cause the second antennas to transmit a second set of power waves via the second antennas to generate a second constructive interference pattern at the second location of the second receiving device.
