Perturbation of the Fractal Sierpinski gasket enables design flexibility in tuning for the required operating bands within a single antenna structure.
Poor matching characteristics
are obtained when the perturbed Sierpinski gasket antenna ((h1/h2)=0.75
) is mounted over a large metallic ground plane. By using a planar microstrip
feed, this impedance mismatch can be overcome. The microstrip feed technique
also play an important role in tuning the operating frequency ratio between
the first and second resonance band (f1/f2).
C. Puente (Fractus) has been a wonderful source of inspiration. Many thanks for his encouragement and sharing of his excellent thesis
