| 摘 要： | 为了优化超宽带天线的阻抗带宽,提出了一种改进的杠铃形超宽带天线,通过增加阶梯形缺口及采用部分接地面从而改善超宽带阻抗匹配。测量结果表明,天线的输入阻抗带宽达74.7%（3.45~7.56 GHz）,同时数值仿真表明在y-z和x-z平面方向图呈对称分布。

| Abstract: | In order to optimize the impedance bandwidth of ultra-wide band(UWB) antenna,a kind of improved barbell-shape UWB antenna is proposed.The impedance matching of UWB is improved by adding the stepped appearance gaps and adopting the partial ground plane.The measured results shows that input impedance bandwidth of the improved antenna is up to 74.7%(3.45~7.56 GHz).The symmetrical distribution in the y-z and x-z planes of radiation patterns are obtained by numerical simulation. |
