| 摘 要： | 设计了一种采用共面TEM馈电结构的抛物反射面超宽谱脉冲辐射天线,分析了该种馈电结构的阻抗特性与辐射特性。实验表明当馈入电压为3kV、前沿180ps的超宽谱脉冲时,该天线主轴辐射场测试距离与峰值场强之积平均值达到18.3kV,相较于常用的TEM喇叭馈电的超宽带反射面天线,其辐射效率有了显著的提高。

| Abstract: | An ultrawide band paraboloidal reflector antenna for ultra-high repetition pulse has been developed. For improving radiant efficiency, the antenna adopted a new coplanar TEM feed structure, and the impedance and radiation characteristics were analyzed. Results show that the rEpmax value is about 18.3 kV and rEpp value is about 35.7 kV when the antenna is excited by a pulse of 180 ps risetime and 3 kV peak voltage. Compared with those antennas with TEM horns, this kind of antenna has the best radiating property. |
