• A gap waveguide-based compact rectangular waveguide to a packaged microstrip inline transition 

      Pérez Escudero, José Manuel Upna Orcid; Torres García, Alicia E. Upna Orcid; Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid (MDPI, 2020)   Artículo / Artikulua  OpenAccess
      In this paper two different simple to design and easy to manufacturing transitions from a microstrip to rectangular waveguide based on ridge and groove gap waveguides are studied. The first one is based on a combination ...
    • Novel design method for millimeter-wave gap waveguide low-pass filters using advanced manufacturing techniques 

      Santiago Arriazu, David; Gómez Laso, Miguel Ángel Upna Orcid; Lopetegui Beregaña, José María; Arregui Padilla, Iván Upna Orcid (IEEE, 2023)   Artículo / Artikulua  OpenAccess
      In this paper, a groove gap waveguide (GGW) low-pass filter is proposed for the first time. Gap waveguide technology represents an interesting alternative as a low-loss, cost-effective, high- performance transmission line ...
    • Robust design of 3D-printed W-band bandpass filters using gap waveguide technology 

      Santiago Arriazu, David; Tamayo-Domínguez, Adrián; Gómez Laso, Miguel Ángel Upna Orcid; Lopetegui Beregaña, José María; Fernández-González, José Manuel; Martínez, Ramón; Arregui Padilla, Iván Upna Orcid (Springer, 2022)   Artículo / Artikulua  OpenAccess
      In this paper, a W-band 3D-printed bandpass filter is proposed. The use of higher-order TE10n modes in groove gap waveguide (GGW) technology is evaluated in order to alleviate the manufacturing requirements. In addition ...
