Radiation characteristics of coaxial waveguides as a small primary feed
Abstract
The radiation patterns of coaxial waveguides with a TE(11) exciting mode are computed numerically. It is shown that by a proper selection of the coaxial aperture dimensions the symmetry of the copolar patterns can be improved considerably. Coaxial radiators can therefore be designed as a useful small primary feed for paraboloid reflector antennas.
