A Compact Design of Ultra-Wideband Antenna with Effective Triple Band-Notched Features

Abstract- A new design of ultra-wideband (UWB) antenna with triple band-notched feature is presented, in which the rectangle radiation patch is applied. The bandwidth of the UWB antenna is extended by using circle corner for the rectangle cut from the ground. A parasitic element is inserted, where an inverse U-shaped slot is cut on the top of the CPW ground plane and a U-shaped slot is cut on the rectangle radiation patch. Thus a triple band-notched feature is obtained, by which the potential interference between UWB and WLAN (Wireless Local Area Networks), C-band and X-band systems is effectively reduced. The new antenna also exhibits desirable directional radiation characteristic. Index Terms- Ultra-Wideband Antenna, Notched Band Featur
