With satellite applications in mind, the authors have analyzed an array of dielectric loaded horns. They outline some of the methods used and present preliminary results, including a shaped beam for an AUSSAT satellite. Reflection and mutual coupling, dielectric loss, and radiation are considered. The horn analysis software was used to design a shaped beam to cover New Zealand from the AUSSAT geostationary positions of 156°E and 160°E. An optimized transmit beam at 12.5 GHz, obtained with a 1.5-m offset parabolic reflector and a seven-element feed array, is shown.
