A compact fractal UWB antenna with open-ended quarter wavelength slot for band notch characteristics

A compact fractal ultra-wideband antenna with band notch characteristics is presented and analyzed in detail. Open-ended quarter wavelength slots are etched in the radiating patch to create the notch band in 5.15-5.825 GHz assigned for IEEE802.11a and HIPERLAN/2. Simulated results shows good broadband matched impedance characteristics and good Omni-directional radiation pattern. The antenna can be effectively used in UWB communication systems.
