Abstract
A compact coplanar waveguide fed UWB (ultra-wideband) antenna with triple band-notched characteristics is presented. The rectangle radiation patch is used in the new design, and the bandwidth of the UWB antenna is extended by using circle corner for the rectangle cut from the ground. A parasitic element is added, whereas an inverted 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. As a result, a triple band-notched characteristic is obtained, by which the potential interference between UWB and WLAN (Wireless Local Area Networks), C-band and X-band systems can be effectively reduced.
