ABSTRACT:
A horn antenna arrangement comprising an H-plane sectoral horn 19 in combination with a feeder waveguide 2 in which radio-frequency energy is launched and propagated in the fundamental rectangular waveguide TE(1,0) mode and provided with a mode-converting section 25 of suitably shaped waveguide of reduced height in which the fundamental TE(1,0) rectangular type mode in, e.g. a planar arcuate input cross section 26, is smoothly and gradually converted into the fundamental TM(0,1) mode of an H-plane sectoral horn in an output cross section 30 which is cylindrically curved about the z axis forming the central axis of sectoral flare for the horn 19, substantially without generating any higher horn modes.
