| 摘 要： | 提出了共面波导(CPW)馈电平面圆形单极子带阻超宽带(UWB)天线的设计方法,采用该方法设计的天线满足超宽带无线通信所要求的3.1 GHz~10.6 GHz的频带范围,通过在圆形贴片上添加U形和弧形缝隙,可分别实现4.75 GHz~5.96GHz范围内和4.8 GHz~6.2 GHz范围内电压驻波比VSWR≥2的带阻特性,均避免了5 GHz无线局域网的干扰。采用电磁仿真软件CST进行了天线的方向图绘制,仿真结果表明该设计可行。

| Abstract: | A design method of a band-notched CPW-fed planar circular monopole UWB antenna is presented.This antenna can satisfy the spectrum requirement of UWB wireless communications which covers a spectrum range from 3.1 GHz to 10.6 GHz.The band-notched character(VSWR≥2)is achieved by adding a U slot on the circular patch when spectrum is from 4.75 GHz to 5.96 GHz and by adding a curve slot when spectrum is from 4.8 GHz to 6.2 GHz.The interference of the WLAN(5 GHz)is avoided.The radiation patterns are illustrated with the electromagnetic simulation software CST,and the results indicate that the design is reasonable. |
