<p>A compact antenna system that permits orthogonally polarized frequency reuse operation is achieved by two overlapping parabolic reflectors. Each of the reflectors has a reflecting surface comprised of parallel, reflecting, conductive elements with the reflecting elements of one reflector polarized orthogonally to the reflecting elements in the other. each reflector has an associated feed copolarized with the reflecting elements of the particular reflector. The two reflectors are overlapped, without coinciding their respective focus points, near their vertices and at their more nearly flat ends. Consequently, cross-polarized fields generated by the parallel elements in the surface of each reflector from its associated feed are scattered away from the copolarized beam of each reflector and further the structure is compact, particularly along the desired axis of reflection.</p> |
