      This paper presents the design, fabrication and characterization of a planar broadband chessboard structure to reduce the radar cross-section (RCS) of an object. The chessboard like configuration is formed by combining two ...

    • Development of ultrathin metasurface and partially reflective surface antennas for space applications 

      Tellechea Pereda, Amagoia Upna Orcid (2017)   Tesis doctoral / Doktoretza tesia  OpenAccess
      La industria espacial ha estado siempre muy interesada en la evolución de las antenas que se integran en los satélites. Se buscan soluciones que además de ser ligeras y compactas, tengan un coste reducido. De esta forma ...

    • Dispersion properties of an elliptical patch with cross shaped aperture for synchronized propagation of transverse magnetic and electric surface waves 

      Tellechea Pereda, Amagoia Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Gonzalo García, Ramón Upna Orcid; Iriarte Galarregui, Juan Carlos Upna Orcid (MDPI, 2018)   Artículo / Artikulua  OpenAccess
      This paper presents a novel pixel geometry for the implementation of metasurfaces requiring synchronized phase propagation of transverse magnetic (TM) and transverse electric (TE) modes. The pixel is composed by an elliptical ...

    • Dual circularly polarized broadside beam metasurface antenna 

      Ederra Urzainqui, Íñigo Upna Orcid; Tellechea Pereda, Amagoia Upna Orcid; Caminita, Francesco; Martini, Enrica; Iriarte Galarregui, Juan Carlos Upna Orcid; Gonzalo García, Ramón Upna Orcid; Maci, Stefano (IEEE, 2016)   Artículo / Artikulua  OpenAccess
      This paper presents the design of a modulated metasurface (MTS) antenna capable to provide both righthand (RH) and left-hand (LH) circularly polarized (CP) boresight radiation at Ku-band (13.5 GHz). This antenna is based ...

    • EBG superstrate antenna for WAAS bands 

      Osés de León, Ángel Upna; Iriarte Galarregui, Juan Carlos Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Gonzalo García, Ramón Upna Orcid (2008)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Multiband antennas can simplify considerably the complexity of receivers and transmitters, reducing the size and the mass of the conventional configurations. On the other hand, applications with high directivity requirements ...

    • Experimental validation of a Ku-band dual circularly polarized metasurface antenna 

      Tellechea Pereda, Amagoia Upna Orcid; Caminita, Francesco; Martini, Enrica; Ederra Urzainqui, Íñigo Upna Orcid; Teniente Vallinas, Jorge Upna Orcid; Iriarte Galarregui, Juan Carlos Upna Orcid; Gonzalo García, Ramón Upna Orcid; Maci, Stefano (IEEE, 2018)   Artículo / Artikulua  OpenAccess
      The experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ...

    • Research on metamaterials for antenna applications 

      Gonzalo García, Ramón Upna Orcid; Ederra Urzainqui, Íñigo Upna Orcid; Iriarte Galarregui, Juan Carlos Upna Orcid; Martínez Pascual, Beatriz Upna; Sáenz Sáinz, Elena Upna; Cantora Álvarez, Pablo; Maagt, Peter de (2005)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      During the last 20 years a lot of attention has been paid to apply Electromagnetic Band Gap (EBG) technology in different frequency ranges, from microwaves to optics. EBG technology is based on the use of periodic structures ...

    • Surface waves of finite size electromagnetic band gap woodpile structures 

      Ederra Urzainqui, Íñigo Upna Orcid; Iriarte Galarregui, Juan Carlos Upna Orcid; Gonzalo García, Ramón Upna Orcid (EMW Publishing, 2011)   Artículo / Artikulua  OpenAccess
      This paper studies the surface modes at the interface of finite size Electromagnetic Band Gap (EBG) woodpile structures. The impact of different types of woodpile terminations on the properties of these surface modes is ...

    • Terahertz time domain spectroscopy allows contactless monitoring of grapevine water status 

      Santesteban García, Gonzaga Upna Orcid; Palacios Horcajada, Inés Upna; Miranda Jiménez, Carlos Upna Orcid; Iriarte Galarregui, Juan Carlos Upna Orcid; Royo Díaz, José Bernardo Upna Orcid; Gonzalo García, Ramón Upna Orcid (Frontiers Media, 2015)   Artículo / Artikulua  OpenAccess
      Agriculture is the sector with the greatest water consumption, since food production is frequently based on crop irrigation. Proper irrigation management requires reliable information on plant water status, but all the ...
