A compact ultrawideband CPW-fed monopole antenna is presented that includes dual band-notch characteristics. The antenna consists of a modified V-shaped patch with two resonant structures to create the required band-notch function at the desired frequency bands to mitigate interference from WLAN and WiMAX systems. The band-notch structures comprise of a rectangular-shaped conductor backed plane and a rectangular-shaped slot inserted within the antenna patch. The center frequency of the band-notch can be varied prior to fabrication without affecting the antenna's overall characteristics. The antenna's performance was verified through measurements, which show that it operates across a large bandwidth between 2.9 and 12.7 GHz for VSWR <2 and provides band reject performance between 3.3-3.8 GHz and 5.2-5.8 GHz. The antenna's dimensions are 19.5 x 21 x 1 mm3.
