A new and efficient design of a rectangular corrugated waveguide mode converter,
from TE10 mode in a smooth rectangular monomode waveguide to HE11 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.
