Abstract A modified Sierpinski fractal Ultra WideBand (UWB) antenna with band notch characteristic is proposed to refrain the interference from WLAN. The radiating path is the modified fourth order Sierpinski fractal structure. The bandwidth of the antenna is effectively expanded and can cover the bandwidth of UWB band (3.1~10.6 GHz) by using coplanar waveguide feed technology and increasing the number of iterations of Sierpinski fractal. The notch band characteristic in 5.03~5.85 GHz is realized by adding two symmetrical L-shaped stubs on the fractal path, which can effectively suppress the interference of WLAN. The antenna has a compact size, and the simulation and measurement results show that the antenna can be widely used in all kinds of UWB communication systems.
