CPW-fed UWB antenna with band-notch by hexagonal shape slot

In this paper, a compact band-notch UWB antenna with CPW-fed is presented. A band notch antenna is designed by etching a band resonance hexagonal shape in the radiation element of the conventional UWB antenna. This antenna is capable of reducing the interference at the WLAN bands by eliminating the 5-5.7 GHz band. The proposed antenna has compact size of 16 × 26 mm

. This miniature size provides a good radiation patterns with mono-polar characteristics. In this designed antenna, the gain is suppressed very well in the desired WLAN bands.
