Abstract
A radio wave control system according to the present disclosure includes a high power amplifier that generates broadband local signals including a first local signal having a first frequency and a second local signal having a second frequency, a reflective plate that modulates, when the first local signal and the second local signal are reflected by or transmitted through periodically disposed antenna elements, the first local signal and the second local signal, and beam-forms the first modulated signal and the second modulated signal in respectively different directions, and a control apparatus that controls directions in which the first modulated signal and the second modulated signal are beam-formed by electrically controlling the antenna elements and controlling phases of the first local signal and the second local signal incident on the reflective plate.
