Simulation of Radiation Characteristics of Sierpinski Fractal Geometry for Multiband Applications
Keywords:
Sierpinski, fractal antenna, multiband antenna.Abstract
The choice of adopting the periodical geometries
like fractals for wireless applications has been a usual practice
considering their geometrical ease in supporting multiband.
Among the traditional fractal geometries Sierpinski, Koch are
some to name with paramount applications in multiband
fractal antennas. In this work we simulated Sierpinski
structures for frequencies close to wireless LAN applications
which would allow for further modifications to reproduce exact
resonant frequencies required for this application. The efficient
CAD tool of High Frequency Structure Simulation software
package is used to design the required geometry of the
proposed fractal antennas. The Finite Element Method based
solver of electromagnetic models in HFSS is employed to solve
the modeled geometry. Various reports like radiation pattern,
reflection coefficient curves, VSWR and field distribution are
generated to study the characteristics of the geometries.
