Abstract :
Electrical characteristics of a hybrid-mode circular aperture horn with dual-depth corrugations are presented. It is shown that the hybrid-mode characteristics of such a horn can be optimised to give low crosspolarised radiation in two bands having arbitrary separation. This is achieved by means of appropriate choice of the depth of successive corrugations. Measured results are given for a horn designed to operate in two bands separated by 1:1.5.
