In this article, two types of mixed-mode magic-Ts are proposed, which can realize out-of-/in-
phase equal power divisions of multiple mixed modes ports with high isolation, common …

In this brief, a high-order dual-band differential bandpass filter (BPF) with two controllable
passbands and attractive common-mode (CM) rejection is proposed. The designed filter is …

With the development of communication technology, the allocation of frequency spectrum is
becoming more intensive. As an important communication component, reconfigurable filters …

Adopting multimode hairpin ring resonator (HRR) and multiarm defected ground slot (DGS),
a new class of dual-band common-mode filter with flexible frequency ratio and bandwidth is …

Two new compact balanced-to-balanced diplexers composed of two multiband balanced
bandpass filters in a multilayer configuration are proposed in this letter to perform dual-and …

This paper reports on the design and experimental validation of a new class of frequency-
tunable filters with switchable bandpass-to-bandstop transfer function characteristics. Single …

This paper presents a frequency-reconfigurable dual-band radio frequency (RF) crossover
based on quarter-wavelength coupled lines (CLs) and open stubs. Initially, an even–odd …

The design of balanced filters based on composite right/left hand (CRLH) structure is well
developed. Among those, few designs exist which although they provide some good …

This article proposes a filtering structure consisting of two half‐wavelength resonators and
two open‐stub loaded resonators, which generates two third‐order passbands. Multiple …

Multifunctional, integrated, and independent microwave sensor (MS) with dual-band
bandpass filter (BPF) for solid material characterization and radio frequency communication …
