      In this paper, a novel waffle-iron filter with transmission zeros at multiple frequencies, along with its design procedure, is presented. The proposed filter features a high-power behavior and a wide rejected band in a ...
    • Passive microwave component design using inverse scattering: theory and applications 

      Arnedo Gil, Israel Upna; Arregui Padilla, Iván Upna; Chudzik, Magdalena Upna; Teberio Berdún, Fernando Upna; Lujambio Genua, Aintzane Upna; Benito Pertusa, David Upna; Lopetegui Beregaña, José María Upna; Gómez Laso, Miguel Ángel Upna (Hindawi, 2013)   Artículo / Artikulua  OpenAccess
      We briefly review different synthesis techniques for the design of passive microwave components with arbitrary frequency response, developed by our group during the last decade. We provide the theoretical foundations based ...
    • Producing and exploiting simultaneously the forward and backward coupling in EBG-assisted microstrip coupled lines 

      Percaz Ciriza, Jon Mikel Upna; Chudzik, Magdalena Upna; Arnedo Gil, Israel Upna; Arregui Padilla, Iván Upna; Teberio Berdún, Fernando Upna; Gómez Laso, Miguel Ángel Upna; Lopetegui Beregaña, José María Upna (IEEE, 2016)   Artículo / Artikulua  OpenAccess
      In this paper, a methodology is proposed for the design of EBG-assisted coupled line structures in microstrip technology, controlling independently the forward and backward coupling. It is based on the use of a ...
    • Rectangular waveguide filters with meandered topology 

      Teberio Berdún, Fernando Upna; Percaz Ciriza, Jon Mikel Upna; Arregui Padilla, Iván Upna; Martín Iglesias, Petronilo; Lopetegui Beregaña, José María Upna; Gómez Laso, Miguel Ángel Upna; Arnedo Gil, Israel Upna (IEEE, 2018)   Artículo / Artikulua  OpenAccess
