A new dual-band bandpass filter (BPF) is designed and fabricated based on a pair of
spherical dual-mode resonant cavities using 3-D printing technology. By elaborately …

A new structure based on an ellipsoidal cavity that operates with the fundamental mode and
its degenerate in a transverse routing scheme is presented in this letter. This configuration …

A novel waveguide step‐twist integrated with a bandpass filter is presented in this Letter.
The twist is composed of four equally rotated cavities to achieve polarisation rotation and …

This article presents metal 3-D printed wideband bandpass filters based on a deformed
elliptical cavity resonator. The resonator can produce a wide stopband response by realizing …

This article presents a Ka-band fourth-order slotted spherical resonator waveguide
bandpass filter (BPF) with a wide spurious suppression stopband. It uses the first higher …

A 3-D printed narrowband bandpass filter based on spherical dual-mode resonators is
presented in this article. It is designed for output multiplexers (OMUXs) using high-spherical …

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 …

Dielectric printed and plated waveguide components offer cost and weight benefits over
metal-printed equivalents, with silver plating using Tollens reagents holding significant …

This paper demonstrates the current state-of-the-art in low-cost, low loss ruggedized
polymer-based 3-D printed G-band (140 to 220 GHz) metal-pipe rectangular waveguide …

This article reports on a new class of highly miniaturized nested spherical bandpass filters
(BPFs) alongside a monolithic integration concept. Miniaturization is achieved by a nested …
