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.

Abstract
The present disclosure describes a plurality of antenna arrangements that may be suitable for wireless power transmission based on single or multiple pocket-forming. Single or multiple pocket-forming may include one transmitter and at least one or more receivers, being the transmitter the source of energy and the receiver the device that is desired to charge or power. ‘The antenna arrangements may vary in size and geometry, and may operate as a single array, pair array, quad arrays or any other suitable arrangement, which may be designed in accordance with the desired application.

5. A system for transmitting wireless power, the system comprising:
a first device comprising a controller, a transmitter coupled to the controller, a communications component coupled to the controller, and a plurality of antennas coupled to the transmitter; wherein the controller of the first device is configured to control the plurality of antennas of the transmitter such that a first set of the plurality of antennas transmits a first set of power waves to generate a first constructive interference pattern at a first location of a second device; wherein each antenna of the first set of the plurality of antennas is a first type of antenna; wherein the communications component is configured to receive a communication signal containing a second location of the second device; and wherein upon receiving the communication signal containing the second location, the controller of the first device is further configured to; select, based on the second location, a second set of the plurality of antennas to transmit a second set of power waves to the second location of the second device, wherein each antenna of the second set of the plurality of antennas is a second type of antenna distinct from the first type, and control the plurality of antennas such that the second set of antennas of the plurality of antennas is used to transmit the second set of power waves to generate a second constructive interference pattern at the second location of the second device. - View Dependent Claims (6, 7, 8, 14, 15, 16, 17, 18)
