Abstract
Method and apparatus for wirelessly transmitting and receiving power between devices are provided. A first device may convert power into RF energy and transmit the RF energy to a second device. In some implementations, the first device may steer the RF energy using beamforming techniques to the second device. The second device may receive and convert the RF energy into power for the second device. In some implementations, the second device may be powered solely or in part by power transmitted by the first device. In some implementations, the first device may include two or more RF energy harvesters and a power combiner. The power combiner may combine power from the two or more RF energy harvesters to power the second device and/or charge a battery.
