Abstract: The wireless power transmission is a system for providing wireless charging and/or primary power to electronic/electrical devices via microwave energy. The microwave energy is focused onto a device to be charged by a power transmitter having one or more adaptively-phased microwave array emitters. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and/or for primary power.

This information is used by the system to adjust the transmitting phases of the microwave array emitters until a maximum microwave energy is reported by the device to be charged. Backscatter is minimized by physically configuring the microwave array emitters in a substantially non-uniform, non-coplanar manner.
