摘要：
In this paper, a dual-reflectarray antenna is proposed to generate a contoured beam for a DBS European coverage. The antenna optics is based on a compact range dual-reflector antenna, which produces low crosspolar radiation. The phase distribution of the subreflectarray is defined to simulate an equivalent hyperbolic subreflector with negative eccentricity. The phase distribution on the main reflectarray surface is synthesized to shape the beam providing the required coverage.
