A Printed-Circuit antenna for UWB systems is presented. The antenna consists of a rectangular slot etched out from the ground plane of a RT/Duroid 5880 (dielectric constant = 2.2) and a CPW-fed bowtie stub for excitation. The antenna is successfully designed, implemented and measured. A compact antenna area of 31.8 x 34.2 mm2 is obtained. The proposed antenna in this study is capable of measured a very wide
operating bandwidth approximately 2.93–11.97 GHz.
