A Coplanar Stripline Filter With Out‐of‐Band Absorption for Wideband Operation
IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.This article presents a coplanar stripline (CPS) reflectionless filter that integrates out‐of‐band absorption, exploring a novel configuration that promotes applications of reflectionless filters. By taking advantage of the CPS structure, the CPS absorptive resonator is initially proposed and studied to keep lossless transmission at its resonance and ...

A fundamental limit on the performance of geometrically-tuned planar resonators [PDF]
, 2011 Geometric frequency tuning in planar electromagnetic resonators is common in many applications. It comes, however, at a penalty in the resonance quality, Q0. The literature traces the causes of such penalty often in terms of the shortcomings in the added

Single‐Layer Fourth‐Order SIW Filtering Antenna With Controllable Radiation Nulls
IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.This paper proposes a filtering antenna utilising single‐layer substrate‐integrated waveguide (SIW) dual‐mode cavities. The TE110 and TE210 modes of the first dual‐mode cavity produce a radiation null (RN) above the passband, whereas the two hybrid modes of the other dual‐mode cavity, excited together through a long slot, introduce another RN below the
