This paper presents a novel multiband waveguide filter model employing cylindrical
resonators arranged horizontally and vertically in Olympic and parallel topologies …

This article presented a modified coaxial resonator, ie, the graded dumbbell coaxial
resonator (GDCR), which can be constructed by concaving the lateral surface of the inner …

This paper proposes a high-Q multiband waveguide filter implementation using spherical
resonators and an in-band transmission zeros approach. Three prototype filters in Ku-band …

In this contribution, a novel quart-torus cavity for the design of waveguide filters is presented.
A filter breadboard based on this kind of cavity is designed at-band, and then fabricated …

A general and direct synthesis of poles pseudo-elliptic inline filters having purely real and/or
imaginary frequency transmission zeros is presented. Using an appropriate model of the …

The design concept of a pole-generating resonant iris is demonstrated in rectangular
waveguide filters in this paper. Different from conventional reactive iris, the resonant iris can …

This article introduces and analyzes the modified metal plate coupled resonator (MPCR),
which can be designed to exhibit distinctive nondegenerate dual-mode characteristics, ie …

This article presents a new class of compact, inline waveguide bandpass filters with sharp
rejection capabilities at the upper stopband using a novel nonlinear frequency variant …

The design of a wideband diplexer integrated with a 16‐slot Continuous Transverse Stub
(CTS) antenna array is presented. The diplexer‐antenna array module covers the whole …

This letter presents a three‐dimensional (3‐D) printed metallic antenna array that combines
folded‐shorted patches (FSPs) and meandering for structure compactness. The design …
