摘要
提出一种用于超宽带系统的小型化平面单极天线,采用共面波导馈电,其辐射贴片采用矩形与半椭圆形组合的结构,使其在3.1～17GHz的频带内驻波比<2,同时引入开环谐振结构实现频带抑制,使其在5.1～5.9GHz的频带内驻波比>2。仿真结果与实测结果匹配良好。
A CPW-fed compact printed monopole antenna is proposed for portable UWB devices. The semielipse and rectangle structure are combined as the radiator to improve the bandwidths of antennas to 3.1 - 17 GHz VSWR 〈 2 ）. The open-loop resonator is also introduced to achieve frequency notched characteristic at 5.1 - 9 GHz （ VSWR 〉 2）. The measured results are in good agreement with the simulated ones.
