Résumé :

In this paper, we proposed a novel integrated ultrawideband(UWB) monopole antenna with dual-band antenna.The antenna consists of planar rectangular with semi-ellipticalbase and a rectangular dielectric resonator (DRA) with dualbandoperation. Both of them are excited via coplanar waveguide(CPW) lines. The numerical results show that the planarmonopole provides a -10dB impedance bandwidth between 2GHzand 12 GHz which largely covers the entire UWB spectrum, andthe rectangular DRA operates at two bands; 5.7-6.2 GHz and 8.2-9.7 GHz. The electromagnetic analysis is carried out using CSTmicrowave studio and HFSS software. The numerical results,obtained from simulation, are given and compared in terms of Sparameters and radiation patterns.
