    • Reconfigurable dual-polarized beam-steering broadband antenna using a crossed-strips geometry 

      Ramírez Arroyave, Germán Augusto; Zhou, Ivan; Blanch Boris, Sebastián; Towfiq, Asaduzzaman; Cetiner, Bedri Artug; Romeu Robert, Jordi; Jofre Roca, Lluís (Institute of Electrical and Electronics Engineers (IEEE), 2021-08)
      Article
      Accés obert
      In this letter, a reconfigurable dual-polarized broadband antenna with beam-steering capabilities using a parasitic layer is proposed for 5G new radio (NR) frequency range 1 (FR-1) applications. The antenna is a dual-port ...

    • Small-size broadband multi-element antenna for RF/wireless systems 

      Cetiner, Bedri Artug; Jofre Roca, Lluís; Qian, J. Y.; Flaviis, Franco de (IEEE, 2003-10-31)
      Article
      Accés obert
      We present a small-size broadband antenna specifically designed for integration with RF/wireless communication systems. The antenna is built on a printed circuit board and fed by a coplanar waveguide (CPW) to allow further ...
    • Study of interconnecting switch currents in reconfigurable parasitic layer antennas 

      Ramirez, German; Araque, Javier; Ballesteros Sánchez, Christian; Blanch Boris, Sebastián; Romeu Robert, Jordi; Cetiner, Bedri Artug; Jofre Roca, Lluís (2019)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      This work presents an approach for calculating the currents across the switches of a reconfigurable parasitic layer intended to add beam-steering capabilities to a reference antenna. The method of analysis is based on the ...
    • Three-dimensional microfabricated broadband patch antenna for wiGig applications 

      Mopidevi, Hema Swaroop; Hurneli, H. V.; Cagatay, E.; Biyikli, N.; Imbert Villà, Marc; Romeu Robert, Jordi; Jofre Roca, Lluís; Cetiner, Bedri Artug (2014-01-01)
      Article
      Accés restringit per política de l'editorial
      The design, microfabrication, and characterization of a broadband patch antenna capable of covering the entire IEEE 802.11ad (WiGig) frequency band (57-66 GHz) are presented in this letter. A conductor-backed (CB) coplanar ...
