Abstract

A feed device repeats a frame including multiple subframes to control phases of power transmission signals from multiple first antennas located around each of multiple first power receivers, such that the phases sequentially change while maintaining a phase relation between the power transmission signals, so as to match the phases of the power transmission signals that one of the multiple first power receivers receives from the multiple first antennas. The feed device sequentially changes the phases of power transmission signals that are transmitted from one or more second antennas.
