Abstract: In this paper, the broadband conditions of a reflectarray antenna will be shown using aberration theory. By using aberration theory, the mechanism of the frequency characteristics of the beam shift and gain reduction will be clarified. Further, a method for the mirror surface is described to become wide band. The validity is verified by an analysis and a theoretical formula.

Keywords: Reflectarray, Aberration, Beam shift, Gain reduction.
