Abstract :
A new and efficient design of a rectangular corrugated waveguide mode converter, from TE/sub 10/ mode in a smooth rectangular monomode waveguide to HE/sub 11/ mode in a corrugated rectangular waveguide, is proposed. The main idea is the application of Gaussian design techniques, described in the given references, previously applied in circular waveguides. By using these techniques compact and very efficient components are obtained. The obtained far field pattern is rather good as illuminator of square or rectangular parabolic reflectors, with very low sidelobes and crosspolarisation levels, avoiding the use of a rectangular to circular waveguide converter. Simulations by using the HP´s finite element code, HFSS, shown very promising results.
