60 GHz single-layer slot-array antenna fed by groove gap waveguide
Ferrando Rocher, Miguel; Valero Nogueira, Alejandro; Herranz Herruzo, José I.; Teniente Vallinas, Jorge
(IEEE, 2019)
Artículo / Artikulua 
A V-band single-layer low-loss slot-array antenna is presented in this letter. Radiating slots are backed by coaxial cavities, which are fed through a groove gap waveguide E-plane corporate feed network. Cavity resonances ... -
Compact groove diamond antenna in gap waveguide technology with broadband circular polarization at millimeter waves
Pérez Quintana, Dayan ; Torres García, Alicia E. ; Ederra Urzainqui, Íñigo ; Beruete Díaz, Miguel (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 ... -
Ultrathin sub-terahertz half-wave plate with high conversion efficiency based on zigzag metasurface
Moreno-Peñarrubia, Alexia; Kuznetsov, Sergei A.; Beruete Díaz, Miguel (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. ...
