“…While measurement results were not presented, there was reasonable room to believe that the results obtained through simulations were reliable. For example, in [16,17,21,25], comparisons between measured and simulated results were reported, and it could be seen that there was a good match between the two. The simulated results presented in this paper are therefore believed to be reliable.…”

The paper presents simulation-based investigations of a circularly polarized (CP) X-band conical horn with an inserted metallic cone-sphere. The performance of this horn is compared with that of dielectric-loaded and unloaded circularly polarized short horns. It emerges that in general, inserting a metallic cone-sphere improves the overall radiation performance of the unloaded circularly polarized horn better than dielectric loading.

“…In [11], the short horn antenna, which is installed in an artificial lens using a combination of epsilon positive and epsilon near zero materials near a horn aperture, achieves a wide impedance bandwidth and a relatively monotonic antenna gain, but the design is more complex. To retain the advantages of a horn antenna, such as monotonic antenna gain, wide bandwidth, and simplicity, short horn antennas with wide flare angles using inserted metallic objects such as discs [12], baffles [13], and spheres [14,15], have been investigated. The insertion of either metal discs or baffles into short horns has also enhanced both the antenna gain and aperture efficiency; however, the gain and efficiency are not monotonically varied.…”

This study presents a very short pyramidal horn antenna for monitoring the radiation characteristics of mobile base‐station (BS) antennas operating in the long‐term evolution (LTE)/cellular band. The proposed short pyramidal horn is integrated with metal strips/rods to overcome deficiencies of the shortened horn, especially in its front‐to‐back (F/B) ratio. The proposed short horn antenna improves the average F/B ratio by at least 8 dB in the frequency range from 690–960 MHz by controlling the edge diffraction. The total length of the antenna, including a waveguide flange, is only approximately 0.6 λ at 800 MHz. The proposed antenna also retains good characteristics such as a monotonically increasing gain, wide bandwidth, and a good purity of polarisation. The proposed antenna can replace the dipole antenna as a reference gain antenna for both indoor and outdoor measurement systems below the L‐band.

In present work we introduce simple metal baffles for improving the gain of horn antenna. The baffle dimensions and distance from the feed are optimized without loading the feed. Performance of baffles like hemisphere, shuttle and variants of ellipse has been studied. Simulation based analysis for 20-30 GHz reveals that gain >21 dB can be achieved with a tradeoff of poor input matching at the edge frequencies. In this work parametric study is done to achieve S 11 <-10 dB and gain >20 dB with radiation pattern discussed. These proposed structures have shown good performance and are suitable for applications requiring compact and high gain horn antennas.
