Amplitude Tapered Leaky‐Wave Antennas in Bent Additively Manufactured Nonradiative Dielectric Waveguides

open access: yesIET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
We introduce a simple approach to taper the amplitude distribution in leaky‐wave antennas by exploiting a nonradiative dielectric waveguide topology. By shaping the dielectric section, the longitudinal attenuation constant and therefore the amplitude distribution can be easily controlled to lower side lobe levels.

Analysis of Substrate Integrated Waveguide (SIW) Resonator and Design of Miniaturized SIW Bandpass Filter

open access: yesInternational Journal of Electronics and Telecommunications, 2017
Abstract In this paper, the substrate integrated waveguide (SIW) resonator is designed to study the influence of dielectric materials on its operating parameters (insertion loss, fractional bandwidth and unloaded Q-factor). The results obtained show that the use of high permittivity substrate in the SIW resonator by increasing its thickness allows

A High‐Efficiency L‐Band Planar Array Antenna Using a Shielded Suspended Stripline Feed Network on a Lossy FR‐4 Substrate

open access: yesIET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
This paper presents a high‐efficiency L‐band 6 × 6 planar array antenna using a shielded suspended stripline feeding network on a low‐cost FR‐4 substrate. The proposed architecture significantly reduces feeding loss by confining electromagnetic fields within a quasi‐air region.

Uniform Circular Array Antenna for Dual‐Mode Orbital Angular Momentum Generation at 6 GHz

open access: yesInternational Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
Orbital angular momentum (OAM) antennas have recently attracted attention for their potential to enhance communication capacity and and robustness against interference. However, most existing designs rely on complex multilayer feed structures. This work presents a compact, single‐layer, series‐fed dual‐mode OAM antenna composed of four patches arranged
