    • 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 Upna Orcid (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      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, Dayan Upna Orcid; Torres García, Alicia E. Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Beruete Díaz, Miguel Upna Orcid (IEEE, 2020)   Artículo / Artikulua  OpenAccess
      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 ...
    • A gap waveguide fed circular polarization antennas in the millimeter wave range 

      Pérez, Dayan Upna Orcid; Torres García, Alicia E. Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Beruete Díaz, Miguel Upna Orcid (IEEE, 2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 ...
    • Ultrathin sub-terahertz half-wave plate with high conversion efficiency based on zigzag metasurface 

      Moreno-Peñarrubia, Alexia; Kuznetsov, Sergei A.; Beruete Díaz, Miguel Upna Orcid (IEEE, 2020)   Artículo / Artikulua  OpenAccess
      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. ...
