1. A method for transmitting wireless power, the method comprising:

  • transmitting, by a first set of a plurality of antennas of a transmitter, a first set of power waves that form a first constructive interference pattern at a first location of a receiver, wherein each antenna of the first set of the plurality of antennas is a first type of antenna;

    receiving, by a communications component of the transmitter, a communication signal containing a second location of the receiver; and

    upon receiving the communication signal containing the second location;

    selecting, based on the second location, a second set of the plurality of antennas of the transmitter to transmit a second set of power waves to the second location of the receiver, wherein each antenna of the second set of the plurality of antennas is a second type of antenna distinct from the first type; and

    adjusting, by a controller of the transmitter, the plurality of antennas such that the second set of the plurality of antennas is used to transmit the second set of power waves to form a second constructive interference pattern at the second location of the receiver.
