  ABSTRACT: This paper presents the design of a 5 m aperture three-reflector offset-fed Cassegrain antenna. A set of rotating fast-scanning mirrors installed at the feed aperture enables one-dimensional rapid scanning observation from geostationary orbit. To meet launch vehicle envelope constraints, the 5 m primary reflector employs a segmented construction, and the secondary reflector utilizes a folded-optics design based on its virtual focus. The antenna’s radiation performance was simulated and tested, demonstrating a total main beam efficiency better than 90% and a radiation pattern uncertainty between semi-physical simulation and measurement of better than 1%.
