ABSTRACT:
A wide-angle reflector antenna that substantially eliminates pattern blockage is provided. The reflector antenna includes a paraconic reflector and a feed supportably located in opposed relation to the reflector surface. A curved reflecting surface of the reflector is formed by symmetrically rotating a curve around a longitudinal center axis, wherein the curve also defines an apex on the longitudinal center axis. The curve's focal point may be located on the longitudinal center axis or laterally displaced therefrom.
