Abstract :
A novel printed antenna for ultra-wideband (UWB) applications is presented. The antenna consists of an open annulus strip as a ground plane and an open crescent patch in the inner space of the annulus as a radiating element. The antenna is fed by a coplanar waveguide with a central strip connected to the crescent patch. The antenna has a compact structure, and the total size is 33 times 30 times 1.57 mm. A relative impedance bandwidth of 129% is achieved, which covers 3-14 GHz.
