Abstract (en)
[origin: DE19817766A1] The invention relates to a centrally fed antenna system whose effective reflector surface is formed in such a way that a maximum of the copolar far field is located on the illuminated coverage surface in line with far field requirements and a minimum of the copolar near field is located in the feed system, e. g. on the aperture of a feed horn.
