I.INTRODUCTION:
A. Fractal antenna:
Among these fractal types, Koch curve, sierpinsky gasket, carpet has variety of applications of operating in multiband .it has a wide application in the design of miniaturized wire antenna due to its unique self-similarity nature . to make a compact antenna with more conductivity can be achieved using this fractal structure. Under the expanding need of size reduction in Antenna design with low profile, fractal theory can help provide a great number of solutions for miniaturized antenna

B. Fractal with slot structure:
Fractal along with slot can help in improving return loss value which helps the antenna to operate in perfect matching condition. This selective adding of slot along the fractal length can improves
