Fig. 1
Far sidelobes at 30 GHz. The main beam points to the top of the map (θ = 0°). The main and sub-reflector spillover regions are highlighted with red contours. The main-reflector spillover points at about 85° from the main beam pointing direction and it is peaked at about 2 dBi. The subreflector spillover is mainly due to the feed sidelobe and peaks at about –8 dBi.
