Abstract
A systematic procedure is derived in which it is possible to shape a dual offset system with elliptical aperture, to provide uniform phase and prescribed amplitude taper over the aperture, which can be rotated with respect to the plane of offset. The approach is demonstrated through an example, which confirms the validity of the technique. A design has been made for a 45/spl deg/ rotation of the main reflector aperture, and compared to a conventional design without rotation.<>
