  • 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)
    Conference report
    Open Access
    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 ...

    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)
    Conference report
    Open Access
    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 ...

  • 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
    Restricted access - publisher's policy
    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?
