Abstract :
The effect of placing a dielectric slab over a 
corrugated feed horn is investigated. The feed horn is normally a circular waveguide with concentric grooves in the aperture plane. Here we simulate the feed horn with a two-dimensional configuration which is a parallel-plate waveguidewith adjacent notches. The equivalence principle and modal analysis are used to formulate integral equations which are solved numerically by the method of moments. Numerical results for the input admittance are obtained with and without the corrugation and with and without the dielectric slab cover.
