In this article, high selectivity filtering antennas are designed based on a mixed-mode cavity
resonator, which is formed by adding a short-circuited metal cylinder at the center of a …

In this article, new resonant coupling structures are proposed for designing miniaturized
waveguide bandpass filters. The resonant coupling structure is constructed by adding one or …

Multimode resonators (MMRs) can be utilized to build multiband bandpass filters (MBPFs).
Each individual mode serves as the operating mode for one of the passbands in a well …

This work presents a design technique to implement miniaturized cross-coupled bandpass
filters in inline physical configurations based on triple-mode resonators. Triple-mode …

Waveguide components have been widely explored for several decades, due to their
inherent merits of low insertion losses, high quality (<; i> Q<;/i>) factors, and a significant …

Electromagnetic (EM) mixed coupling creates transmission zero (TZ) either at lower or upper
stopband of bandpass filter (BPF) with inline configuration of resonators. This is a very …

This article presents two types of dual-narrowband/wideband filters using modified coaxial
cavities with large frequency ratios. The dual-narrowband/wideband filters mean two dual …

Stopband-improved substrate-integrated waveguide (SIW) triplexer and triple-band filters
are presented based on the novel realization method of coupling topologies composed of …

In this letter, a high selectivity frequency selective surface (FSS) with three independently
controllable transmission poles (TPs) is proposed by using matrix synthesis. The response …

In this design, an adjustable triple-band triple-mode dielectric waveguide (DW) bandpass
filter with multiple transmission zeros (TZs) is presented. The design involves creating blind …
