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'editorialA 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 obertA 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'editorialMiniature 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'editorialA 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 ...
