Main reflector synthesis of omnidirectional reflector antennas using elliptical sections

Abstract

The present paper aims to extended a formalism to synthesize the main reflector of an omnidirectional axis-displaced Cassegrain (OADC) through two case studies. The numerical synthesis is based on the consecutive concatenation of elliptical sections. Furthermore, a power distribution pattern it specified on the reflector cylindrical aperture to produce, according to Geometrical Optics, a sectoral coverage. The shaping results are validated using method-of-moments (MoM) analysis.
