摘要
设计加工了一种宽频带柱面共形天线,采用共面波导(CPW)形式对其进行馈电。对比了平面天线的特性变化,分析了柱体曲率半径对天线阻抗特性和辐射特性的影响。测量结果表明,该天线具有宽频带特性,可用频段覆盖1.8～11.2GHz,在工作频段内具有较好的全向辐射特性,增益稳定。
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.
