Abstract
A quad ridge horn antenna is presented as a feed for a reflector antenna for use in radio astronomy applications. The antenna uses shaped sidewalls to limit the variation of beamwidth over the frequency range and to obtain greater radiation pattern rotational symmetry. The antenna is dual-polarized and matched over more than a 4:1 bandwidth.
