Abstract

In this paper, we propose originals structures of monopole microstrip antennas for UWB applications with Hilbert curve Defected Ground Space (DGS) structure. These Antennas are made of two different shapes of slot inside a square patch, fed by a 50 Ω microstrip line on a FR4 dielectric substrate. A 3rd iteration of the Hilbert space filing curve is cut out from a partial ground plane. These antennas have a wide bandwith varying from 3.21 GHz to 13.64GHz and from 3.18 GHz to 14.32 GHz for S11< -10dB. Details of the two antenna designs approach and simulated results are presented and discussed in this paper.
