A novel ultra-wideband antenna with diamond-shaped patch was designed and fed by a coplanar waveguide.The size of the substrate is 26 mm×24 mm×0.8 mm and the substrate material uses FR4 with a relative permitivity of 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.
