Abstract
The design of dual-reflector antennas with a spherical main reflector for small earth stations is considered. An analysis of the field polarization throughout the system shows that it is possible to adjust the reflectors to obtain very low cross-polarization. The use of an elliptical main reflector projection is explored in order to enhance efficiency and lower side-lobe levels.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
