In this paper, we propose a novel integrated ultra-wideband (UWB) monopole antenna with dual-band antenna. The antenna consists of planar rectangular with semi-elliptical base and a rectangular dielectric resonator antenna (DRA) with dual-band operation. Both of them are excited via coplanar waveguide (CPW) lines. The experimental measurements show that the planar monopole provides an impedance bandwidth between 2.44 and 11.9GHz which largely covers the entire UWB spectrum, and the rectangular DRA operates at two bands; 5.3-6.2 and 8.5-9.4GHz. Additionally, the proposed structure ensures low mutual coupling between the two ports (with S-21 less than -20dB in the whole operating frequency band). The measured and numerical results show a good agreement.
