Abstract
A horn-reflector microwave antenna comprises the combination of a paraboloidal reflector for transmitting and receiving microwave signals; a tapered feed horn extending downwardly from the reflector for guiding microwave signals to and from the reflector; a waveguide connected to the lower end of the feed horn; and a dielectric membrane extending across the interior of the feed horn for collecting any debris that falls down into the feed horn. In the preferred embodiment of the invention, the outer periphery of the dielectric membrane is secured to the interior walls of the feed horn, and the central portion of the membrane is elevated above the periphery thereof so that debris collected on the membrane slides to the walls of the feed horn.
