An integral waveguide device herein includes a polarizer component comprising a waveguide and a dielectric slab, the dielectric slab configured to change a polarization of a signal passing through the waveguide. The integral waveguide device also includes a feed horn for conveying signals between the waveguide and a parabolic antenna. The waveguide of the polarizer and the feed horn are manufactured as an integral component with the feed horn disposed at a first end of the waveguide.

Integrated polarization converter and feed horn

A method for providing frequency selective surface zoning includes selecting a location for positioning a frequency selective surface (FSS) panel along a support arm of a reflector antenna system, and positioning a second feed horn on the support arm on an opposite side of the FSS panel. A number of unit cells are used to populate the FSS panel, and metallic patterns are formed on each unit cell. Multiple zones are subsequently defined on the surface of the FSS panel. Each zone is optimized for a predetermined range of incident angles.
