Fractal antennas have the potential to provide multi-band solution through the property of self similarity that the fractal shape possess. This thesis deals with some modifications of the original Sierpinski fractal patch antenna, providing additional parameters to optimize in order to get the required radiation characteristics. A systematic study of the original Sierpinski monopole was done to gain an insight on the operation and multi-band behavior of the antenna and a similar study was done to find out why the patch version of Sierpinski lacks multi-band behavior. A Sierpinski antenna is designed by merging a grid and the fractal restoring the multi-band behavior. A stacked Sierpinski antenna is then designed by introducing an intermediate layer containing the triangular patch whose size is equal to that of the triangular hole in the fractal structure. The introduction of a gap in this structure improves the overall radiation pattern. The antennas are analyzed using the commercial IE3D package and the simulated radiation patterns are presented.
