This paper presents a new class of dual-, tri-and quad-band BPF by using proposed open
stub-loaded shorted stepped-impedance resonator (OSLSSIR). The OSLSSIR consists of a …

A new type of microstrip dual-mode dual-band bandpass filter (BPF) using a single
quadruple-mode resonator (QMR) is proposed in this paper. The classical even-/odd-mode …

This letter presents a dual-mode dual-band bandpass filter using a patch resonator with a
cross slot and two different groups of stubs loaded. The cross slot with different orthogonal …

A single slotted circular patch resonator is proposed in this letter to design a novel dual-
mode dual-band bandpass filter. Four identical arc-oriented slots are first symmetrically …

In this paper, a short-ended stepped-impedance dual-resonance resonator is presented.
Analysis of its resonance characteristics is carried out, from which the design graph is given …

A miniaturized dual-mode microstrip bandpass filter (BPF) based on fractally slotted patch
resonator is presented in this paper. The proposed filter is centered at 2.4 GHz desirable for …

Novel cross-coupled dual-band bandpass filters (BPFs) with compact size are proposed
based on dual-mode isosceles right-angled triangular (IRAT) resonators. The dominant …

This paper describes a stacked spiral resonator (SSR) structure for designing very compact
multiband bandpass filters. The resonant frequencies of the proposed SSR structure can be …

A single annular ring resonator is proposed to design a dual-mode dual-band bandpass
filter (BPF) with adjustable frequency ratio of the two passbands. The two passbands are …

A novel compact dual‐band bandpass filter (BPF) using a hybrid structure of microstrip patch
and coplanar waveguide (CPW) is proposed, designed, and implemented. The dual‐band …
