Abstract: Abstract:In February 2002 the Federal Communications Commission (FCC) in the United States released unlicensed frequency band of 3.1 to 10.6 GHz for commercial communication applications [1]. So far, ultra wide band (UWB) technique had become the first candidate of short-range high-speed wireless communication systems. The antenna is an important component, which determines the performance of UWB systems; moreover one of principal subjects in UWB device is to design a compact antenna. Recently, UWB antenna development tends to concentrate on small planar antennas [2–3]. UWB antennas are also necessary for the rejection of an interference with existing wireless networking technologies such as IEEE 802.11a in the U.S. (5.15~5.35 GHz, 5.725~5.825 GHz) and HIPERLAN/2 in Europe (5.15~5.35 GHz, 5.47~5.725 GHz) [4-7]. This is due to the fact that UWB transmitters should not cause any electromagnetic interference on nearby communication system such as wireless local area network (WLAN) applications. Therefore, UWB antennas with notched characteristics in WLAN requency band are desired. To fulfill this requirement, an UWB antenna with a band-stop characteristic is therefore expected. So far, several UWB antennas with the frequency-notch function have been reported. The advantages of slot antennas include wide andwidth performance and low cost in the printed circuit board rocess, and als CPW fed slot ntenna also have wide andwidth and easy integration with monolithic microwave integrated circuits.
