  • A mechanism to electrically enlarge the ground plane of handset antennas: A bandwidth enhancement technique 

    Anguera, Jaume; Andújar Linares, Aurora; Puente Baliarda, Carles (2011-07)
    Article
    Restricted access - publisher's policy
    There is a need of developing new techniques for enhancing the bandwidth of handset antennas without increasing the antenna volume in order to incorporate more frequency bands into the cell phones. The technique to enhance ...
  • Analysis of the human body on the radiation of FM handset antenna 

    Vergés, J.; Anguera, Jaume; Puente Baliarda, Carles; Aguilar, David (2009)
    Article
    Restricted access - publisher's policy
    A simple human body phantom model is proposed and used to demonstrate that the radiation efficiency of an internal handset antenna operating at the FM band can be improved for a particular holding position up to 10 dB. ...
  • Broadband triple-frequency microstrip patch radiator combining a dual-band modified Sierpinski fractal and monoband antenna

    Article
    Restricted access - publisher's policy
    Abstract—A triple-frequency antenna combining a dual-band and a monoband antenna with broadside radiation patterns is presented. The dual-band antenna is inspired in the Sierpinski fractal. Such a dual-band antenna is ...
  • Dual frequency broad-band stacked microstrip antenna using a reactive loading and a fractal-shaped radiating edge 

    Anguera, Jaume; Puente Baliarda, Carles; Borja, C.; Soler, J. (2007-07-02)
    Article
    Restricted access - publisher's policy
    A dual-band enhanced-bandwidth microstrip antenna is presented with a frequency separation of f2/f1=1.37. In order to achieve the dual-frequency operation, a rectangular patch antenna is reactively loaded with a stub ...
  • Dual frequency broadband microstrip antenna with a reactive loading and stacked elements 

    Anguera, Jaume; Puente Baliarda, Carles; Borja, C. (2009)
    Article

    A dual-band enhanced-bandwidth microstrip antenna is presented with a frequency separation of f2=f1 = 1:33. In order to achieve the dual-frequency operation, a rectangular patch is loaded with a stub at one of its radiating ...
  • Enhacing robustness of handset antennas to finger loading effects 

    Anguera, Jaume; Camps, Albert; Andújar, A.; Puente Baliarda, Carles (Institution of Electrical Engineers, 2009-07-17)
    Article
    Restricted access - publisher's policy
    A novel handset antenna consisting of two small antennas is proposed to mitigate finger loading effects. Both antennas are excited with a different phase in order to maximise the bandwidth. A phantom hand has been used to ...
  • Metallized foams for fractal-shaped microstip antennas 

    Anguera, Jaume; Daniel, Jean Pierre; Borja, C.; Mumbru, Josep; Puente Baliarda, Carles; Leduc, T.; Laeveren, Nancy; Van Roy, P (2008-12)
    Article
    Restricted access - publisher's policy
    An antenna manufacturing process using metallized foams is presented. A microstrip-patch antenna, inspired by the Koch island geometry, embedded in a rectangular cavity is built and tested. All the metallic parts of the ...
  • Multi-band handset antenna combining a PIFA, solts, and ground plane modes 

    Cabedo, Arnau; Anguera, Jaume; Picher, C.; Ribó, Miquel; Puente Baliarda, Carles (2009)
    Article
    Restricted access - publisher's policy
    A multiband handset antenna combining a PIFA and multiple slots on a ground plane is presented. It is shown by means of simulations that the slots on the ground plane have a double function: to tune the ground plane resonance ...
  • Multiband handset antenna with a parallel excitation of PIFA and slot radiators 

    Anguera, Jaume; Sanz, Ivan; Mumbru, Josep; Puente Baliarda, Carles (2010-02)
    Article
    Open Access
    A handset antenna technique combining a parallel excitation of a PIFA and a slot is presented. The number of frequency bands is given by the sum of bands given per each radiator which can be controlled independently. ...
