Monotonically increasing gain-versus-frequency pattern is in general expected to be a characteristic of aperture antennas that include the smooth-wall conical horn. While optimum gain conical horns do naturally exhibit this behavior, nonoptimum horns

This article presents a comparative study based on measurements and simulations of a Ku-band conical horn with an inserted metallic cone-sphere with horns having an integrated dielectric lens and meta material loading. The results revealed that the p

Two recent methods that have been reported in the literature to improve the performance of pyramidal horns are metal ba†e loading and the use of epsilon-near-zero metamaterial. In this paper, a comparative study of the two methods is undertaken for

The conical horn gain is expected to increase with increasing flare angle until it reaches a maximum and then should decrease. The available closed-form approximation for conical horn loss factor, and hence gain, is examined in this paper in this bac

In this work, the recently proposed metallic cone-sphere-inserted conical horn is proposed as an alternative to the hybrid mode dielectric-loaded horn. The proposal is verified by comparing the performance of the two designs in the Ku-band. The compa

A dielectric-loaded conical horn exhibiting improved radiation characteristics - low cross-polarization and side-lobes levels, pattern symmetry and good front-to-back ratio-is proposed. The dielectric insert is simpler than the ones proposed in two e

The design and simulation-based analysis of a 4-28 GHz double ridged conical horn is presented in this work. While the horn offers a VSWR of less than 1.6 over the entire bandwidth, it also exhibits desirable radiation patterns. More importantly, as

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 retur

A metallic cone-sphere-inserted smooth-wall conical horn operating in the Ku-band that offers improved return loss compared to similar, recent designs is proposed. The other desirable characteristics, namely high gain and compact size, of the earlier

It is shown in this work that the performance of the recently proposed normal circular polarized smooth wall conical horn (CPSWCH) is improved by using metallic cone-sphere insertion. The performance of the proposed circular polarized horn is better
