Madrid, septiembre de 1996.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 ).4 p.application/pdfspaAntenas de bocina multimodoHaz gaussiano fundamental de alta purezaContribución a congreso / Biltzarrerako ekarpenaAcceso abierto / Sarbide irekiainfo:eu-repo/semantics/openAccess
