    • Small but long koch fractal monopole 

      Puente Baliarda, Carles; Romeu Robert, Jordi; Pous Andrés, Rafael; Ramis, J; Hijazo, A (Institution of Electrical Engineers, 1998-01)
      Article
      Accés obert
      A small but long wire fractal antenna based on the Koch curve is presented. Experimental and numerical results show that the antenna improves the features of a common linear monopole. The radiation resistance is increased ...

    • The Koch monopole: a small fractal antenna 

      Puente Baliarda, Carles; Romeu Robert, Jordi; Cardama Aznar, Ángel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 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 ...
