摘要

对一种平面维瓦尔第天线进行了重构，并对其作为近距离、高距离分辨率铁路截割监测雷达的候选天线进行了评估。研究发现，Vivaldi天线的初始耀斑部分可以控制该天线在较低频率下的回波损耗，并通过实验证明了一个120%分数带宽的紧凑型天线。采用群延迟作为超宽带天线的评估方法，原型天线在考虑的下半段频段内具有合理的性能。

Vivaldi antenna for railway cutting monitoring

A planar Vivaldi antenna was reconstructed and assessed as a candidate for a short range, high range resolution railway cutting monitoring radar. The initial flare section of the Vivaldi antenna was found to control the return loss of this type of antenna at lower frequencies, and a compact antenna for 120% fractional bandwidth was demonstrated experimentally. Group delay was used as a UWB antenna assessment method, and the prototype antenna gave reasonable performance across the lower half of the band considered.
