There has been an ever-growing demand, in both the military as well as the commercial sectors for antenna design that possess the following highly desirable attributes: compact size, low profile, conformal and multi-band or broadband. In this paper, the authors provide overview of recent developments in the rapidly growing fields of fractal antenna engineering. Emerging applications of wireless communication system demand adaptability and unobtrusiveness in antenna system. Besides this the main constraint in advanced telecommunication systems are performances, size, weight, cost, ease of installation of antenna. One of the successful approach is "Fractal antenna".
