| Abstract: | A cylindrical conformal antenna fed by CPW is proposed and fabricated.The changes of the impedance characteristic and radiation patterns with different radius were analyzed when the planar antenna was mounted on the cylinder.The measured results show the antenna has a good wideband capability,its operation bandwidth covers from 1.8~11.2GHz.The omni-directional radiation property and stable gain can be achieved at each operation frequency. |
