| Abstract: | A novel ultra\|wideband antenna with diamond shaped patch was designed and fed by a coplanar waveguide. The size of the substrate is 26mm×24 mm×0.8 mm and the substrate material uses FR4 with a relative permitivityof 4.4. The patch was optimized twice by ground plant’s first order optimization. The simulated and experimental results demonstrate that the bandwidth (VSWR≤2) starts from 2.0 GHz up to 14.5 GHz and relative bandwidth comes to 151%. This diamond shaped UWB antenna has the advantages of simple structure and miniaturization that can be applied to various UWB systems. |
