Microwave band pass filters play an important function in radio frequency for suppressing
out-of-band emissions that are necessary in today's wireless communication. The study …

This article proposes a new class of box-like substrate integrated waveguide (SIW) filters
with wide stopband. First, a two-pole doublet bandpass filter with one finite-transmission …

A novel miniaturized bandpass filter (BPF) with high stopband rejection based on a hybrid
structure is proposed with shielded quarter-mode substrate integrated waveguide (QMSIW) …

In this paper, a systematic research campaign on eighth-mode substrate integrated
waveguide (EMSIW) filters is reported. The sizes of these EMSIW resonant cavities are only …

This article investigates flexibly using mixed coupling in substrate integrated waveguide
(SIW) filters to efficiently improve selectivity. To this end, a mixed coupling structure is …

This paper expands our previous work on planar tunable capacitive coupling structures in
substrate-integrated cavities using lumped components. We demonstrate both frequency …

In this paper, a novel simple horizontal electric coupling (SHEC) structure is proposed,
which only requires a single elliptical ring slot to be etched at the top layer of the substrate …

In this study, a substrate integrated waveguide (SIW) combined with complementary split‐
ring resonator (CSRR) structure is proposed for high‐sensitivity measurement of complex …

This paper presents a novel method to widely tune high-quality factor evanescent-mode
cavity resonators and filters using contactless tuners. The proposed method resolves …

This communication presents substrate integrated coaxial resonator (SICR) based triple-
mode bandpass filters designed for K u-band. A self-shielded SICR based third-order filter is …
