A novel CPW fed Sierpinski carpet fractal UWB slot antenna

Abstract

A Novel coplanar waveguide (CPW) fed Ultra Wideband (UWB) antenna is presented. The proposed antenna is designed on RT/duriod 5880 substrate with thickness of 1.57 mm and relative permittivity of 2.2 having loss tangent 0.0009 using a second iteration Sierpinski carpet fractal with overall dimension of 37 mm x 46 mm x 1.57 mm. The designed antenna offers a good impedance bandwidth from 3.1 to 11 GHz. The presented antenna has omnidirectional radiation pattern and good gain flatness suitable for UWB applications.
