ABSTRACT:
An antenna comprises the combination of a biconical-horn and a circular waveguide. The major symmetry plane of the horn is horizontal and the horn describes a figure of revolution about the major axis of the circular waveguide. Coupled to the one wall of the horn with its axis perpendicular to the horizontal symmetry plane of the horn is the circular waveguide. A TEM coaxial port on the vertical axis of the horn is provided at the vertex of the cone forming the surface of the biconical-horn. Two orthogonal-ports are provided in the circular waveguide with two respective TEM transmission lines extending from within the circular waveguide outside of these ports to provide at their outputs the TE.sub.11 modes.
