| 摘 要： | 研制了一款超宽带印刷单极子天线。通过在接地板和单极子贴片底部开槽，展宽了天线频带，改善了天线带内特性，提高了天线增益。采用HFSS软件进行仿真，对天线模型参数进行优化，达到最佳设计效果。结果表明，改进后的天线-10 dB阻抗带宽为2.2~14.6 GHz，比原不开槽天线的-10 dB阻抗带宽增加了7.2 GHz。天线实现了小型化超宽带的同时，在整个超宽带匹配频段内，具有良好的驻波和方向图特性，在超宽带设备中有着很好的应用前景。

| Abstract: | The Ultra-Wideband(UWB) printed monopole antenna proposed in this paper is notched in the ground plane and the monopole patch, so that the inner band performance is improved and the bandwidth is further expanded at the high frequency section. The gain of the antenna is improved. The parameters of the antenna are simulated and optimized with HFSS, and the best antenna design is got. The simulated result shows the -10 dB impedance bandwidth of the improved antenna is 2.2-14.6 GHz in contrast to 2.5-7.7 GHz of the initial antenna, as a result, the bandwidth is enhanced by 7.2 GHz. The antenna meets the requirements of the UWB and has good voltage standing-wave ratio performance. Furthermore, good radiation patterns indicate that the proposed antenna is well suited to be integrated within various devices for ultra-wideband application. |
