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.
