This article reports on a new class of additive manufacturing (AM) and monolithically
integrated multiband coaxial bandpass filters (BPFs). They are based on in-series cascaded …

This paper presents a newly developed metal 3D printed waveguide bandpass filter based
on a modified deformed elliptical cavity resonator with an additional plate. The modified …

In this paper, a groove gap waveguide (GGW) low-pass filter is proposed for the first time.
Gap waveguide technology represents an interesting alternative as a low-loss, cost …

This chapter intends to show the strong potential brought by metal 3D-printing to the field of
waveguide components and antennas. General co-design guidelines are firstly provided …

This work presents a new topology of evanescent mode filter (EMF) that allows for its
efficient additive manufacturing (AM). Chamfered ridges which avoid the appearance of …

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 …

This article presents a new approach to manufacturing and assembling inexpensive,
lightweight devices using 3-D-printed waveguides, and surface-mount technology (SMT) …

An-band filtering crossover based on ellipsoidal cavities has been designed, fabricated
using 3-D printing, measured, and presented. The crossover is designed to have three …

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 …

This research delves into losses of X-band cavity resonators manufactured using additive
manufacturing-selective laser melting (AM-SLM) compared to the standard subtractive …
