1. An antenna feed system adapted to provide directional antenna beams from an antenna array having a plurality of antenna elements arranged in columns which are disposed along a curve, said system comprising:

  • a plurality of beam former circuits, each said beam former circuit adapted to provide a predetermined phase progression with respect to signals associated with selected ones of said columns, said predetermined phase progression being at least in part a function of said curve, each said beam former circuit also adapted to provide aperture tapering by coupling signals of outer ones of said selected ones of said columns differently than inner ones of said selected ones of said columns.
