Abstract
In this paper, a novel Ultra-Wideband(UWB) antenna fed by CPW is designed, fabricated, and measured for UWB communications. We have used the Microwave Studio of CST to simulate the proposed antenna. It is designed to work on a substrate TMM4 of thickness 0.762 mm and relative permittivity 4.5. The proposed antenna is satisfied with Ultra-Wideband communication band from 3.1 GHz to 11.5 GHz, for VSWR$\leq$2, and isolated IEEE 802.1la frequency band(5.15 GHz$\~$5.825 GHz) using a rectangular slot. Measured group delay variation is less than 1 ns, thus indicating the proposed antenna a good candidate for UWB applications.
