RCA 69,530, A SUBWAVELENGTH MONOPULSE ANTENNA Abstract of the Disclosure, A sum channel waveguide is excited in a TE11 mode to cause a radio frequency wave to propagate therefrom through a cylindrical multimode waveguide. The wave propagates via a discontinuity that causes the multimode waveguide to be excited in the TE11 mode and higher order modes. The multimode waveguide is coupled to free space via a dielectric lens and a cup shaped matching section, whereby the wave causes a beam to be radiated from the lens. The cavity of the multimode waveguide is contiguous with a plurality of arcuate cavities of a difference channel waveguide. The beam is deflected in response to excitation of the …
