      Pérez Quintana, Dayan Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Beruete Díaz, Miguel Upna Orcid (IEEE, 2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      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 ...
    • Compact bull's-eye antenna in ridge gap waveguide with circular polarization at 60 GHz 

      Pérez Quintana, Dayan Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Beruete Díaz, Miguel Upna Orcid (IEEE, 2021)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work, a Bull's-Eye (BE) antenna with circular polarization (CP) based on ridge gap waveguide (RGW) technology, working in the millimeter-wave band (60 GHz) is numerically and experimentally demonstrated. The structure ...
    • A gap waveguide fed circular polarization antennas in the millimeter wave range 

      Pérez Quintana, 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 ...
    • Metal 3D printed D-Band waveguide to surface wave transition 

      Freer, Suzanna; Martinez, Rafael; Pérez Quintana, Dayan Upna Orcid; Beruete Díaz, Miguel Upna Orcid; Hanham, Stephen M.; Attallah, Moataz M.; Navarro Cía, Miguel Upna Orcid (IEEE, 2020)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      The coupling efficiency between free space waves and surface waves is low, narrowband, or both. Highly efficient broadband (better than 20% fractional bandwidth) coupling from waveguide modes can be achieved through ...
