  • High directivity fractal boundary microstrip patch antenna 

    Borja Borau, Carmen; Font, G; Blanch Boris, Sebastián; Romeu Robert, Jordi (Institution of Electrical Engineers, 2000-05)
    Article
    Accés obert
    A novel patch antenna with a fractal boundary condition is proposed. Experimental and numerical results corroborate the fact that the fractal characteristic of the perimeter produces localised modes. This property is ...

  • Design of single shaped reflector antennas for synthesis of shaped contour beams using genetic algorithms 

    Vall-Llossera Ferran, Mercedes Magdalena; Rius Casals, Juan Manuel; Duffo Ubeda, Núria; Cardama Aznar, Ángel (2000-12)
    Article
    Accés restringit per política de l'editorial
    A genetic algorithm (GA) has been developed for designing single-shaped reflector antennas for the synthesis of shaped contour beams. The graphical processing technique is used in order to obtain the antenna radiation ...
  • The Koch monopole: a small fractal antenna 

    Puente Baliarda, Carles; Romeu Robert, Jordi; Cardama Aznar, Ángel (2000-11)
    Article
    Accés obert
    Fractal objects have some unique geometrical properties. One of them is the possibility to enclose in a finite area an infinitely long curve. The resulting curve is highly convoluted being nowhere differentiable. One such ...
  • Dual band fss with fractal elements 

    Romeu Robert, Jordi; Rahmat-Samii, Y (Institution of Electrical Engineers, 1999-04)
    Article
    Accés obert
    Experimental and computed results of a frequency selective surface (FSS) based on a certain type of fractal element are presented. The fractal element is a two iteration Sierpinski gasket dipole. Owing to the dual band ...
  • Infrared thermograms applied to near-field testing 

    González, J.M.; Aguasca Solé, Alberto; Romeu Robert, Jordi (Institution of Electrical Engineers, 1999-05)
    Article
    Accés obert
    Electromagnetic fields close to radiant structures can be measured quickly using an infrared camera. Examples of induced fields by wire antennas over a detection screen at distances shorter than one wavelength are presented. ...

  • Active zone self-similarity of fractal sierpinski antenna verified using infra-red thermograms 

    González, J.M.; Navarro Bernal, Manuel; Puente Baliarda, Carles; Romeu Robert, Jordi; Aguasca Solé, Alberto (Institution of Electrical Engineers, 1999-08)
    Article
    Accés obert
    The surface current distribution of a Sierpinski fractal antenna shows a self-similar behaviour determined by the self-similar properties of its geometry. The application of infra-red thermography to electromagnetic near ...
