Abstract
A dual polarized mechanical scan antenna capable of rapid beam scanning includes a parabolic reflector having an elliptically shaped solid metal central section with conductive parallel grids extending therefrom to the perimeter of the paraboloid to form two outer grided sections. The axis of the parabolic reflector and the radiation axis of the feed antenna, positioned at the focus in alignment therewith, is positioned at a predetermined angle from a reference axis of the system. A polarization twist reflector is positioned at the focus for pivoting about the perpendicular to the reference axis. Dual polarization is realized when the twist plate is positioned such that the antenna system receives signals along paths that clear the parabolic reflector.
