    • Fractal FSS: a novel dual band frequency selective surface 

      Romeu Robert, Jordi; Rahmat-Samii, Yahya (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2000-07-31)
      Article
      Accés obert
      The multiband properties of self-similar fractals can be advantageously exploited to design multiband frequency selective surfaces (FSS). A Sierpinski dipole FSS has been analyzed and measured and the results show an ...
