Abstract
Quad-ridge horn antennas of various geometries
are considered as possible candidates for a wideband reflector
antenna feed. It is demonstrated that shaping the sidewalls of the
ridge horns significantly improves the radiation characteristics of
the horns. The conical quad-ridge horn with an elliptically shaped
sidewall shows the most promise as a wideband reflector antenna
feed. The radiation patterns are rotationally symmetric, and the
10-dB beamwidth is reasonably constant over a wide frequency
range.
