Resumen
In this paper, we present an original and optimal multimode horn antenna design to excite the
fundamental Gaussian beam from an overmoded waveguide. In particular, we focus the study in overmoded
circular corrugated waveguide.
The main idea to design this multimode horn antenna, is to increase the waveguide radius as the
desired gaussian mode expands. This principle has also been applied to s ...

In this paper, we present an original and optimal multimode horn antenna design to excite the
fundamental Gaussian beam from an overmoded waveguide. In particular, we focus the study in overmoded
circular corrugated waveguide.
The main idea to design this multimode horn antenna, is to increase the waveguide radius as the
desired gaussian mode expands. This principle has also been applied to smooth circular waveguides to excite
higher order Gaussian beams from TE0n modes.
The horn antenna design considered here, improves the gaussian conversion efficiency, the crosspolarisation
and the sidelobes level of some good mixture ( aprox. 85% of TE11 and 15% of TM11 ). [--]
