Abstract
A method of wireless power transmission includes transmitting, via antenna elements of an antenna array, a plurality of first signals having a first phase and a first gain. The method further includes determining a location of a receiver device based on the plurality of first signals transmitted by the antenna elements of the antenna array. The method includes adjusting, for the antenna elements of the antenna array, one of a phase and a gain based on the location of the receiver device. The method includes transmitting, via the antenna elements, a plurality of second signals having a second phase or a second gain such that the plurality of second signals are focused at a focus region that is approximately the size of an antenna array of the receiver device and provide energy at the focus region that is converted by the receiver device into usable power.
