【摘要】 文章设计了一种共面波导馈电的小型平面超宽带天线。天线由树形辐射单元和共面波导构成,体积小,在工作带宽内具有稳定的方向特性。利用电磁仿真软件对影响天线性能的主要参数进行了仿真、分析和优化,得到了天线的理想尺寸。对优化后的超宽带天线进行制作和测试,测试结果显示天线的工作带宽为3～11GHz。测试结果与仿真结果吻合,从而证明利用共面波导馈电的超宽带天线设计方法的有效性。更多还原

【Abstract】 A compact coplanar waveguide(CPW)-fed ultra-wideband(UWB) antenna is presented in this paper.The antenna is formed by the tree-like radiation unit and the CPW.The antenna has the advantages of small size and stable radiation pattern in the operating bandwidth.The key parameters affecting the performance of the antenna are simulated,analyzed and optimized by using electromagnetic simulation software.The ideal dimensions of the antenna are obtained,and the optimized antenna is manufactured and tested.The result shows the antenna’s bandwidth is 3-11 GHz.The experimental result is in agreement with the simulated result,which shows the design of CPW-fed UWB antenna is feasible.更多还原
