As high data rate wireless communication technologies are gaining importance in modern communication systems, design of an antenna with compact size, simple structure and wide operating frequency range is a challenge. Ultra wide band systems provide wide bandwidth with high data transfer rates and less multi path interference. In 2002, Federal Communication Commission allocated a band range from 3.1GHz to 10.6 GHz for UWB systems. Different varieties of printed slot antennas like L-shaped slot, inverted T-shaped slot etc., are used for UWB applications but they are larger in size. Antenna with parasitic elements also increase the bandwidth but at the cost of size.
