In this paper, the Sierpinski carpet based fractal microstrip antenna with zero, first and second iterations is implemented. Fractal antenna has been extensively investigated because of its multiband operation and compact size. This paper presents a fractal based antenna using Sierpinski carpet geometry. A simple microstrip antenna with the zero iteration, first iteration and the second iteration Sierpinski carpet fractal antenna were designed and optimized. The simple microstrip antenna obtains a return loss of -29.22dB at the resonant frequency of 2.46GHz.
