A K‐Band Dual‐Polarised Hetero‐Integrated Quasi‐Planar Transverse Electromagnetic Antenna

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
In this article, a design of the dual linear‐polarised/dual circular‐polarised transverse electromagnetic (TEM) antenna is presented, which is designed to operate in K‐band (18–19.5 GHz). The Quasi‐TEM wave is achieved by the low‐profile metallic stepped horn antennas and the planar multilayer feeding structure. The cross‐shaped slot and the multilayer

360° beam-steering reconfigurable wideband substrate integrated waveguide horn antenna

, 2016
A novel beam-steering reconfigurable substrate integrated waveguide (SIW) horn antenna is presented. By employing p-i-n diodes as tuning mechanisms, the states of copper posts of the SIW horn can be electronically controlled.

Gain Enhancement of Spoof Surface Plasmon Polaritons Fed Tapered Slot Antenna Arrays

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
This article presents a novel spoof surface plasmon polariton (SSPP) feeding mechanism that overcomes traditional field‐matching limitations in tapered slot antennas. By exploiting the localized hotspots inherent to SSPPs, the proposed design significantly enhances energy transfer efficiency and aperture field uniformity.

Multilayer Universal Transitions Between Substrate Integrated Waveguides and Rectangular Waveguides

, 2022
Even though a large number of transitions between metal waveguides and planar transmission lines/waveguides has been proposed thus far, due to different shortcomings, none of them has gained widespread acceptance comparable to the ubiquitous right-angle ...

Compact Single‐Cavity Dual‐Band SIW Filter Based on Orthogonal Hybrid Loading

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
This graphical abstract presents a dual‐band substrate integrated waveguide (SIW) filter. Orthogonal capacitive‐inductive loading in a single SIW cavity achieves quasi‐independent frequency tuning, independent bandwidth control, two transmission zeros, high interband isolation, and miniaturisation. The proposed filter operates at 5.48 and 8.36 GHz with

Miniaturized Single‐Layer Quasielliptic Response HMSIW Filter With Four Transmission Poles

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
This study presents a miniaturized filter based on half‐mode substrate‐integrated waveguide (HMSIW) resonant cavities, a bent‐line resonator, and a composite right/left‐handed (CRLH) resonator. The filter employs two HMSIW resonant cavities, which effectively reduce its size and prevent the propagation of higher‐order modes TE120 and TE220 within the ...
