On the reflectarray using ring-type resonator elements, a high efficiency design method was adopted and its results were confirmed at the design frequency. In this paper, in addition to the conventional high efficiency design method, a reflectarray w

Aberration theory has been proposed to estimate the frequency characteristics of a reflectarray antenna. In this paper, a multi-beam design of a reflectarray antenna by using first-order aberration is proposed. The validity of the design method is th

In this paper, aberration theory will be introduced to estimate the frequency characteristics of reflectarrays. By introducing aberration theory, the mechanisms of the frequency characteristics of the beam squint and the phase errors on the aperture

A wideband design method for reflectarray antennas with conventional ring-type resonator elements is proposed. It is shown that the one of the causes of the narrow bandwidth is the inadequate attenuation of higher order Floquet modes in the dielectri
