A Review : Microstrip Fractal antenna geometries

With the rapid development of wireless communication system, the main objective is to design of wideband, multiband and small size antenna. To obtains these requirements the fractal antenna is used. The term "fractal" came into the existence in 1975 which means non-regular and never ending pattern. Fractal geometry has advantages of reducing antenna size and obtains multi-band or wideband behaviour; while it's on the other hand drawback is increasing the complexity of antenna design when increasing the iteration number without notifies any enhancement in antenna performance. Also, fractal geometry has two important properties such as space filling and self-similarity. One of the most hopeful areas of fractal-geometry is its application to the design of antenna to produce miniature size and wideband antenna take advantages from their unique properties of self-similarity property and space-filling.
