      Crépin, Thomas; Martel, Cédric; Gabard, Benjamin; Boust, Fabrice; Martinaud, Jean-Paul; Dousset, Thierry; Rodríguez Ulibarri, Pablo Upna; Beruete Díaz, Miguel Upna; Loecker, Claudius; Bertuch, Thomas; Marcotegui, José Antonio Upna; Maci, Stefano (IEEE, 2014)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work, a metaradome based on a fakir’s bed of nails is designed and tested in order to suppress the blind directions of a 100-element antenna array. The antenna is a microstrip array designed to operate in X-band. ...
    • Implementacion de línea de ε negativa en tecnología stripline 

      Illescas, Jesús; Jarauta Ayensa, Eduardo Upna; Estévez, Aritz; Marcotegui, José Antonio Upna; Falcone Lanas, Francisco Javier Upna (2009)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work, a negative-ε equivalent response medium is proponed in stripline technology. To achieve band rejection behaviour, Complementary Split Ring Resonators (CSRR) are placed in the central conductor strip of ...
    • Mejora de antenas metalo-dieléctricas en la banda de frecuencias GSM-UMTS mediante elementos en transmisión extraordinaria 

      Illescas, Jesús; Estévez, Aritz; Falcone Lanas, Francisco Javier Upna; Marcotegui, José Antonio Upna (2009)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In this work a dual band GSM/UMTS antenna is proposed. The antenna is based on a stacked planar structure, where the combination of collimation by Enhanced Transmission and the use of parasitic director elements is ...
