A single-layer circularly polarized array antenna is proposed in the context of the so-called
gap waveguide (GW) technology. This ultracompact antenna combines the corporate …

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 …

The gap waveguide has been recently presented as a new transmission line technology
using artificial magnetic conductors (AMCs) to allow the wave propagation only along a …

The paper describes the design methodology, experimental validation, and practical
considerations of two millimeter-wave wideband vertical transitions from two gap waveguide …

A new kind of contactless electromagnetic bandgap (EBG) structure in the form of interdigital-
pin bed of nails is introduced for the first time in this paper. It consists of two metal plates with …

This paper presents a two-dimensional low-profile Luneburg lens that is designed by using
a glide-symmetric metasurface. The entire lens consists of two mirrored metal plates with …

The first antenna based on substrate integrated gap waveguide (SIGW) is presented. Using
two contacted metal strips to build the required conducting ridge, the SIGW addresses the …

This letter discusses the feasibility of a new type of waveguide consisting of a strip
suspended on a bed of nails. The bed of nails enforces a stopband, while the strip opens a …

A new electromagnetic band gap (EBG) structure based on the soft and hard surfaces for
gap waveguide (GW) technology is introduced in this article. The proposed EBG structure …

In this paper the benefits of using Groove Gap Waveguides (GGW) in the design of
multilayer slotted-waveguide array antennas are presented. Groove Gap Waveguide do not …
