Performance comparison of metallic cone-sphere-inserted and dielectric lens-corrected conical horns

This paper compares the performance of metallic cone-sphere-inserted and plano-convex dielectric lens-corrected conical horns. The parameters considered in the study are gain, aperture efficiency, peak cross-polarization, radiation patterns and return loss. It emerges from the comparative study that, in an overall sense, the metallic cone-sphere-inserted conical horn outperforms the lens-corrected horn.
