Abstract
Fractal based structure are found attractive for
antenna designers to produce a compact size and multi-band
antenna because of their unique properties; space-filling and
self-similarity. In this paper, a new printed fractal based slot
antenna is presented. The slot structure of the proposed
antenna is extracted by applying Cantor fractal geometry to
a circular shape as an initiator. The Cantor based slot
structure has to be etched on the ground plane of a substrate
with relative permittivity of 4.4 and 1.6 mm thickness. A 50
ohm microstrip feed line has been etched on the other side of
the substrate. Modeling and performance evaluation of the
proposed antenna have been carried out using the
commercially available EM simulator HFSS, from Ansoft
corporation. A parametric study carried out to explore the
effects of feed line length on the antenna performance show
that is possesses a triple band behavior with reasonable
radiation characteristics. Simulation results show that the
variation of the antenna aspect ratio results in return loss
responses with tri-band behavior covering a wide variety of
wireless communication applications below 6 GHz.
Furthermore, it has been found that, the modification of the
antenna slot structure results in return loss responses with
dual-band resonances. The proposed antenna provides the
antenna designer with a high degree of freedom.
