Mejoras de los parametros de radiacion de una antena choque-gaussiana para cobertura global

Trabajo presentado al XIX Simposium de la Unión Científica Internacional de Radio (URSI'04). Barcelona, 2004.Extremely low sidelobe horn antennas are often required for the actual technology. This type of horn antennas is important to avoid interference with other systems. In this paper a novel design, consisting in attaching together a choked-waveguide antenna with a classical pure gaussian output corrugated horn is presented. A radiation pattern with very low sidelobes and crosspolar levels in a very short profile is obtained. This antenna shape was firstly presented in [1]. In this paper an improvement in size, weight, bandwidth and crosspolar level of the design is shown. This idea of horn antenna has been patented and PCT extended to several countries; Flann Microwave Ltd. has the rights to commercialize it and has sold several antennas of this type at the moment
