| 摘 要： | 提出了一种新型折线环形超宽带天线的设计,该天线结构类似一般的宽缝隙天线,不同的是采用了折线环结构进行设计。通过采用折线环结构不仅可以获得宽带工作特性,还能实现尺寸缩减。通过数值分析与实验研究,研究了天线的输入反射特性与辐射特性。计算与实测结果表明,该超宽带天线具有超过4:1的工作带宽以及良好、稳定的全向辐射特性,具有很好的理论参考意义与实用价值。

| Abstract: | A novel meandered-loop ultra-wideband antenna was proposed.The antenna was similar in configuration with a conventional wide-slot antenna,however,by employing meandered-loop structure,not only ultra-wideband performance but also compact size could be achieved.It had been investigated both numerically and experimentally for its input performance and radiation characteristics.It is observed that an operation bandwidth of over 4:1 has been achieved.Furthermore,relative stable and good omnidirectional radiation performance have also been achieved.Thus it can be determined as a useful candidate for UWB application. |
