Abstract :
In this paper, a compact dual band-notch UWB antenna with CPW-Ground-fed is presented. It is desired to achieve band notch antenna by etching a narrowband dual resonance fractal binary tree in the radiation element of the conventional UWB antenna. This antenna is capable of reducing the interference at the WLAN bands by eliminating the 4.95-6.05 GHz band. The proposed antenna has compact size of 16 times 22 mm2 including the ground plane. This miniature size delivers a good radiation patterns with mono-polar characteristics. In this proposed antenna design, the gain is suppressed very well in the desired WLAN bands. The maximum suppression is in 5.61 GHz that is 13.25 dB less than the gain of normal antenna.
