Abstract. Present day is witnessing a very rapid growth of wireless communication, for which antenna with very large bandwidth are in strong demand, so that various application are covered with fewer or preferably with single antenna. Fractals are profoundly intricate shapes that are easy to define. Fractals are space-filling contours, electrically large features can be efficiently packed into small areas. Fractal tree structures can be utilise to enhance the performance of the antenna such as widening the frequency band while reducing the size of an antenna. This paper summarize the different kind of tree design structure, development process, current research and application of the fractal tree antenna.
