    • 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)

      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)
      Conference report
      Open Access
      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)
      Conference report
      Restricted access - publisher's policy
      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
      Restricted access - publisher's policy
      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 ...
