This article presents a new decoupling and matching network (DMN) design for symmetric,
single-and dual-band two-element antenna arrays. The DMNs use parallel-line-based …

A dual-band bandpass filter (BPF) composed of a coupling structure and a bent T-shaped
resonator loaded by small L-shaped stubs is presented in this paper. The first band of the …

In this paper, two simple structures, ie, coupled line and T-shaped microstrip structures, are
used to construct four types of quasi-reflectionless (QR) filters, including single-and two-port …

A compact multifunctional switchable filter based on parallel-coupled lines with three
different filtering functions is presented in this letter. By using pin switches to connect or …

A miniaturized broadband on-chip bandpass filter (BPF) is presented based on shunt dual-
layer meanderline resonators and several metal-insulator-metal (MIM) capacitors. To …

In this article, quarter-mode substrate-integrated waveguide (QMSIW) filters featuring
ultrawide stopband and flexibly allocated transmission zeros (TZs) are proposed. Eight …

In this brief, a novel compact single circular patch dual-band (DB) filtering power divider
(FPD) is proposed for the first time. In this design, the modified TM 01 resonance mode (ie …

In this brief, two kinds of wideband high selectivity passband filter chips with adjustable
bandwidth are proposed. Independent controllable transmission zeros are introduced on …

A wide-band band-pass filter (BPF) using coupled lines, rectangular stubs and Stepped-
Impedance Resonators (SIRs) is presented in this paper. The proposed BPF operates over a …

High-order single-ended and balanced wideband bandpass filters (BPFs) with quasi-elliptic-
type (QET) responses are reported. Firstly, a fifth-order wideband BPF based on a two-layer …
