Abstract. The calculation results of
two multibeam offset Dragonian reflector antennas with concave hyperboloidal
subreflectors analysis are presented. Reflector antennas under investigation have a 100 wavelength circular
apertures. The estimation of far fields and antenna efficiency for different
angles of beam deflection in two planes is
performed. The study of cross-polarization characteristics is carried out. Results
of numerical calculations of scanning capabilities for two possible feed
arrangements are shown.
