Compact antennas in ridge gap waveguide with circular polarization
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this paper, two compact antennas in Ridge Gap Waveguide (RGW) technology, working at 60 GHz, with a high-purity circular polarization (CP) within a broad bandwidth are manufactured and measured. The antennas are fed ...
A gap waveguide fed circular polarization antennas in the millimeter wave range
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
In this work, a novel circular polarization (CP) antennas in ridge gap waveguide (RGW) working in the V-band of the millimeter-wave spectrum is presented. CP is generated in a simple and effective way by means of two ...
Full-space metasurface at millimeter-wave frequencies
(IEEE, 2023)
Contribución a congreso / Biltzarrerako ekarpena,
Conventional metasurfaces provide control over the electromagnetic waves in a single working frequency operating either in transmission or reflection. Full-Space Metasurfaces (FSM) are an extension that allows operation ...
Ultrathin sub-terahertz half-wave plate with high conversion efficiency based on zigzag metasurface
(IEEE, 2020)
Artículo / Artikulua,
In this communication, an ultrathin transmissive half-wave plate (HWP) based on a bi-layered zigzag metasurface operating at the lower frequency edge of the terahertz (THz) spectrum is numerically and experimentally studied. ...
Compact groove diamond antenna in gap waveguide technology with broadband circular polarization at millimeter waves
(IEEE, 2020)
Artículo / Artikulua,
In this paper, three compact antennas using the Ridge Gap Waveguide (RGW) technology working in the millimeter-wave band (60 GHz), with a high-purity and broadband circular polarization (CP) are numerically and experimentally ...
