Abstract
In a phased array antenna that has a configuration in which a plurality of antenna panels, in each of which a plurality of antenna elements are arrayed, are connected in the form of a plane and that radiates power transmission microwaves in the arrival direction of a pilot signal sent from an electric-power receiving facility (rectenna system), by controlling the phases of signals input to and output from the antenna elements. An arithmetic processing section, which is provided in each of the antenna panels, calculates the phase shifts of power transmission microwaves to be radiated from the antenna elements. Then, the phase information indicating the phase shifts calculated by the arithmetic processing section is sent to at least three adjacent antenna panels by a transmission and reception section provided in each of the antenna panels.
