Vivaldi antenna for railway cutting monitoring [PDF]
2016 CIE International Conference on Radar (RADAR), 2016 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 ...
