    • Broadband radar cross-section reduction using AMC technology 

      Iriarte Galarregui, Juan Carlos Upna; Tellechea Pereda, Amagoia Upna; Martínez de Falcón, José Luis Upna; Ederra Urzainqui, Íñigo Upna; Gonzalo García, Ramón Upna; Maagt, Peter de (IEEE, 2013)   Artículo / Artikulua  OpenAccess
      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 ...
    • Dispersion properties of an elliptical patch with cross shaped aperture for synchronized propagation of transverse magnetic and electric surface waves 

      Tellechea Pereda, Amagoia Upna; Ederra Urzainqui, Íñigo Upna; Gonzalo García, Ramón Upna; Iriarte Galarregui, Juan Carlos Upna (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; Tellechea Pereda, Amagoia Upna; Caminita, Francesco; Martini, Enrica; Iriarte Galarregui, Juan Carlos Upna; Gonzalo García, Ramón Upna; 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 ...
    • Experimental validation of a Ku-band dual circularly polarized metasurface antenna 

      Tellechea Pereda, Amagoia Upna; Caminita, Francesco; Martini, Enrica; Ederra Urzainqui, Íñigo Upna; Teniente Vallinas, Jorge Upna; Iriarte Galarregui, Juan Carlos Upna; Gonzalo García, Ramón Upna; 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 ...
