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.
Claims39
A reflector antenna comprising:
- a reflector having a curved reflecting surface that extends at least partially around a longitudinal center axis, wherein said curved reflecting surface is defined by rotating a concave curve at least partially around said longitudinal center axis, and wherein one end of the concave curve defines an apex on the longitudinal center axis;
- and
- a feed spaced from and supportably located in opposing relation to the reflectors, wherein said reflector has a single one of a focal point and focal ring that is coincidental with one of a feed phase center and feed focal ring of said feed.
A reflector antenna comprising:
- a reflector having a curved reflecting surface defined by rotating a curve at least partially around a longitudinal center axis, wherein the curve defines an apex on the longitudinal center axis;
- a feed antenna spaced from and supportably located in opposing relation to the reflector;
- and,
- one of a post and a radiolucent radome for supporting said feed antenna.
