A new ultra wideband antenna fed by coplanar waveguide (CPW) is presented in this paper. A fractal structure is constructed to obtain ultra wideband (UWB) performance. The parameters and characteristics of the antenna and the simulation results show that the 6:1 or more bandwidth is achieved with the second order iterative antenna structure
In this paper, a novel UWB printed elliptical monopole antenna is proposed, which provides about 21.6 octave measured impedance bandwidth while its overall size is only about 0.19lambdaltimes0.16lambdal. The bandwidth broadening of this design comes from three factors: an elliptical monopole shape, a trapeziform ground plane and a tapered CPW feeder
