Gary A Martek, Fred E Ashbaugh: High-gain, waveguide-fed antenna having controllable higher order mode phasing. Innova Corporation, Seed and Berry, June 24, 1997: US05642121 (14 worldwide citation)

A diverging shall antenna fed by a waveguide supplying TE.sub.11 mode is described. A dielectric rod partially contained within the waveguide converts the TE.sub.11 mode to a dominant or HE.sub.11 mode. The HE.sub.11 mode is controllably converted to second and third order modes in the diverging she ...
