Abstract

A feed structure for transmitting or receiving microwave energy to or from a reflector includes a waveguide having an input section, intermediate section, and output section. The waveguide has an inner surface of generally rectangular cross section and an outer surface of generally circular cross section. The outer surface includes unique opposing convex surfaces which enables the waveguide to be bent with minimal resulting deformation of the internal rectangular surface. At least one locating surface is provided on the outer surface of the waveguide for determining the orientation of the waveguide.
The input section of the waveguide has a threaded cylindrical surface adapted to be connected to a hub having a threaded interior bore which is connected to the reflector. A
feed horn integral with the output section of the waveguide and having a circular output aperture is formed by machining the inner surface of the waveguide into a rectangular to circular transition. The intermediate section of the waveguide is curved so that the output aperture of the horn is directed toward the reflecting surface of the reflector, enabling waves transmitted from the aperture toward the reflecting surface to be reflected into space in the form of plane waves.
