Abstract: The combination of fractal geometry with electromagnetic theory has led to useful and innovative antenna designs. This paper presents the design of Sierpinski carpet fractal antenna up to third iteration. The proposed antenna is designed on FR4 substrate with dielectric constant of 4.4. The antenna have been optimized to operate in multiple bands between 5-20 GHz. Sierpinski Carpet Fractal Antenna (SCFA) have been analyzed in term of various parameters like return loss, Total Field Gain, Directivity, Radiation pattern & VSWR etc.
