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.

Abstract: A connector assembly for connecting a microwave antenna to a radio unit. The connector assembly comprises a central hub including a waveguide and adapts for connection to the antenna for transmitting microwave signals to and from the antenna. A first latching element is attached to the hub and a second latching element adapts for connection to the radio unit and cooperates with the first latching element for latching and unlatching in response to rotational movement of the second latching element relative to the first latching element.

Abstract: A grid-type microwave antenna comprises a multiplicity of generally parallel conductive rods. Each rod is curved along its length to form a section of a paraboloid so that when all the rods are positioned parallel to each other, in spaced apart relationship to each other, they form a paraboloidal reflector. A rim includes insulating members for receiving and holding the ends of the rods to position the rods in spaced apart and parallel relationship to each other.
