    • Zoned fishnet lens antenna with reference phase for side lobe reduction 

      Pacheco Peña, Víctor Upna; Navarro Cía, Miguel Upna; Orazbayev, Bakhtiyar Upna; Minin, Igor V.; Minin, Oleg V.; Beruete Díaz, Miguel Upna (IEEE, 2015)   Artículo / Artikulua  OpenAccess
      Reduction of first side lobe level and nulls in artificial fishnet metalenses is accomplished here by applying the reference phase concept along with the zoning technique. Higher focusing efficiency is achieved for a ...
    • Zoned near-zero refractive index fishnet lens antenna: steering millimeter waves 

      Pacheco Peña, Víctor Upna; Orazbayev, Bakhtiyar Upna; Beaskoetxea Gartzia, Unai Upna; Beruete Díaz, Miguel Upna; Navarro Cía, Miguel Upna (AIP Publishing, 2014)   Artículo / Artikulua  OpenAccess
      A zoned fishnet metamaterial lens is designed, fabricated, and experimentally demonstrated at millimeter wavelengths to work as a negative near-zero refractive index lens suitable for compact lens antenna configurations. ...
