Abstract :
Profiled dielectric loaded horns are investigated with the aim of obtaining low peak crosspolar level and high aperture efficiency. A number of nonlinear profiles are considered. The paper also looks into the influence of profiling on the bandwidth of the horn and the effect of nonuniformities in the dielectric material on horn performance
