Recently, gap waveguides have been shown as a potential alternative to convenational
waveguides in the millimeter-wave band. Until now, groove gap waveguide (GGW) has …

Gap waveguide is a promising transmission structure, especially for millimeter-wave (mmW)
and terahertz applications. It does not require conductive connection between the upper and …

This paper proposes for the first time a design method of Chebyshev band-pass filters based
on groove gap waveguide (GGW) technology and evanescent mode. The evanescent mode …

Novel types of narrow band filters based on the newly introduced gap waveguide
technology are presented in this paper. The proposed filters have a central frequency of 35 …

Ridge air-gapped waveguide and groove air-gapped waveguide are the most commonly
used air-gapped waveguides. In this work, a full air-gapped waveguide (FGW) is first …

In this paper, we propose a compact topology for high-frequency bandpass filters using
coaxial cavities embedded in a bed of nails, including a complete design procedure …

A novel substrateless power amplifier module realized by ridge gap waveguide (RGW)
technology is proposed in Ka-band. Up to our knowledge, this is the first time that an active …

This paper presents a comprehensive study of a groove gap waveguide (also known as a
waffle-iron) bandpass filter at Ka-band (26.5-40 GHz), fabricated using a high resolution …

This letter presents our study on a compact and low-loss E-band bandpass filter (BPF)
based on multilayer groove gap waveguide (GGW). Different from other reported planar …

A novel real-time rotatable rectangular waveguide twist is presented in this letter. The
proposed waveguide twist is based on the contactless waveguide flange technique. The …
