Abstract
A new class of one-hybrid-mode primary focus feed with high aperture efficiency and low spill-over is described. These antennas are suitable for use in deep parabolic reflectors (F/D<0.35). The propagation characteristics in the horn and far field radiation pattern are derived. The antenna efficiency and spill-over are computed. Finally, the comparison between the theoretical and experimental radiation pattern and possible applications are discussed.
