Abstract
In this paper, we present an original and short corrugated horn antenna
profile to obtain the HE11 corrugated circular waveguide mode exciting with
a pure TE11 monomode smooth circular waveguide mode. We will obtain a
far field pattern with a very low crosspolarization, high symmetry and very
low sidelobes in a wide frequency band.
The proposed corrugated antenna has a longitudinal section c ...

In this paper, we present an original and short corrugated horn antenna
profile to obtain the HE11 corrugated circular waveguide mode exciting with
a pure TE11 monomode smooth circular waveguide mode. We will obtain a
far field pattern with a very low crosspolarization, high symmetry and very
low sidelobes in a wide frequency band.
The proposed corrugated antenna has a longitudinal section composed of
two hyperbolic profiles in series, one concave and the other convex united at
a point, such that the derivative is continuous. Superimposed there is an
additional tapering of the corrugation depth that goes from λ/2 at taper input
to λ/4 within the first hyperbola.
This original synthesis procedure has been successfully tested by
computational simulation. The calculation method has been validated with
experimental results of other authors. [--]
