Because it possesses miniaturization, multiband and integrated, it have became a hotspot of researching in the antenna engineering in present. As koch monopolar fractal antenna for an example, introduces the conception of fractal antennas, the key technique and characteristic, generalizes the application present status of fractal antenna and points out the question that need to be resolved in the researching of fractal antenna.
