The feasibility of replacing the fabricated metallised foam subreflector in dielguides by the shaped dielectric surface has been demonstrated. The design of the shaped surface is based on the principles of geometrical optics. Out of the many curvatures obtained, two shaped surfaces result in a conical main reflector for one case and a conical subreflector for the second case.
