Abstract: Microstrip antenna is the most basic types of antenna which is used now days. The reduced weight and flat profile of these antennas as compared to the parabolic reflector antennas make it attractive for a number of applications. These antennas are less bulky and are capable of resonating at different frequencies but have some disadvantages as low bandwidth and low gain. There are a number of techniques which may be used in order to improve these factors. Using fractal geometry or using DGS are some of these techniques. Design and simulation has been carried out using IE3D simulation software. Sierpinski fractal geometry has been used to form a mushroom shaped patch antenna.

Keywords: Fractal, mushroom shaped, patch antenna.
