リフレクトアレイ

Abstract

This reflectarray comprises: at least one common electrode disposed on the side on which radio waves are incident; at least one bias electrode disposed so as to overlap a back surface of the at least one common electrode; a bias signal line disposed on the back surface side of the at least one common electrode and connected to the at least one bias electrode; and a liquid crystal layer between the at least one common electrode and the at least one bias electrode. The at least one common electrode has a constant potential. A bias voltage for changing the dielectric constant of the liquid crystal layer is applied to the at least one bias electrode via the bias signal line.
