    • Self-similar current distribution on fractal Sierpinski antenna verified with infrared thermograms 

      González Arbesú, José María; Puente Baliarda, Carles; Romeu Robert, Jordi; Aguasca Solé, Alberto (Institute of Electrical and Electronics Engineers (IEEE), 1999)
      Text en actes de congrés
      Accés obert
      Experimental verification of the fractal Sierpinski antenna surface current distribution is presented. Measured data from an infrared camera agree with numerical data showing a self-similar behavior in the current density ...

    • Signal-to-noise ratio equalization for TOPSAR mode using a nonuniform steering rate 

      Ruiz Rodon, Josep; Broquetas Ibars, Antoni; González Arbesú, José María; Closa Domínguez, Josep M.; Labriola, M (2011-09-15)
      Article
      Accés restringit per política de l'editorial
      In this letter, an optimized scanning in terrain observation by progressive scan synthetic aperture radar (TOPSAR) mode is studied. A nonuniform steering rate of the radar array antenna in the along-track direction is ...

    • Sistema de adquisición y procesado de datos en campo próximo esférico 

      González Arbesú, José María; Blanch Boris, Sebastián (1991)
      Text en actes de congrés
      Accés obert
      Near field antenna measurements supply e qua! or more accurate results than far field measurements, its main dijficulty is the post processing of the data measured in the anechoic chamber. In this paper we show a measurement ...

    • Spiral resonator mu-near-zero substrates for grounded slot antennas 

      Ferrer, Pere; González Arbesú, José María; Romeu Robert, Jordi (2010)

    • Tone injection-based cancellation technique for nonlinear distortion reduction of modulated signals in BAW resonators 

      González Rodríguez, Marta; Collado Gómez, Juan Carlos; González Arbesú, José María; Mateu Mateu, Jordi; Montoro López, Gabriel; Gilabert Pinal, Pere Lluís (2020-01-01)
      Article
      Accés obert
      A technique for the reduction of third-order intermodulation distortion (IMD3) occurring in bulk acoustic wave (BAW) filters and multiplexers is presented. The method consists of using the intrinsic second-order intermodulation ...

    • Transpolarizing trihedral corner reflector characterization using a GB-SAR system 

      Ferrer, Pere J.; López Martínez, Carlos; Aguasca Solé, Alberto; Pipia, Luca; González Arbesú, José María; Fabregas Canovas, Francisco Javier; Romeu Robert, Jordi (2011-07)
      Article
      Accés restringit per política de l'editorial
      The use of a low-profile, lightweight, and easy-to-fabricate transpolarizing surface placed on one side of a trihedral corner reflector (TCR) as a polarimetric calibrator is presented in this letter. The transpolarizing ...

    • Trimming the power consumption of domestic Wi-Fi networks: how much power does your router need? 

      Pérez Díaz de Cerio, David; González Rodríguez, Marta; Valenzuela González, José Luis; González Arbesú, José María (2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      This work is part of a project where the goals are: designing energetically-optimum domestic WiFi routers; obtaining real and accurate power consumed models as a function of router configuration, and providing the ...
