    • Reuse of the mobile communication antenna for FM reception 

      Picher, C.; Andújar Linares, Aurora; Anguera Pros, Jaume; Borja, C.; Puente Baliarda, Carles; Kahng, Sungtek (2011)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A conventional monopole antenna (λ/4) operating a t FM frequencies is too long for being integrated in a mobile phone. In order to avoid big external antennas or u sing the wire of the headsets, a new solution is ...
    • The Hilbert monopole revisited 

      Sanz, Ivan; Anguera Pros, Jaume; Andújar Linares, Aurora; Puente Baliarda, Carles; Borja, C. (Institute of Electrical and Electronics Engineers (IEEE), 2010)
      Text en actes de congrés
      Accés obert
      A comparison between the resonant performance of the third iteration Hilbert monopole and a spiral shaped one of the same size and resonant frequency is presented. Quality factor, bandwidth, efficiency and radiation patterns ...
    • The Sierpinski fractal bowtie patch: a multifracton-mode antenna 

      Montesinos, Gemma; Anguera Pros, Jaume; Puente Baliarda, Carles; Borja, C. (Institute of Electrical and Electronics Engineers (IEEE), 2002)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Miniature behaviour of microstrip antennas with Sierpinski bowtie geometry is investigated and the existence of fracton modes is studied. A fracton mode is a mode found at a higher frequency than the one obtained for the ...
    • Theoretical and practical experiments for a single antenna gain testing method. Application to wireless devices 

      Anguera, Jaume; Sanz, Alfonso; Ko, Young Ji; Borja, C.; Puente Baliarda, Carles; Soler, Jordi (2007-08)
      Article
      Accés restringit per política de l'editorial
      A compact antenna gain measurement system suitable for wireless devices is presented. The method needs the antenna under test, a planar electric conductor, and a vector analyzer. It is possible to obtain the total gain ...
