摘要

本文研究了维瓦尔第天线两种不同馈电结构的性能。结果表明，交叉极化的性能取决于导向区和馈电区。进给区的影响非常重要，通过减小进给辐射可以减小交叉极化。比较了带状线馈电双层维瓦尔第天线和Y2Y馈电单层维瓦尔第天线的性能。所设计的天线可用于超宽带微波成像应用。

Comparing performance of double layer stripline fed and single layer Y2Y fed vivaldi antennas

This paper investigates the performance of two different feed structures for Vivaldi antennas. It is shown that cross polarization performance depends on both guiding and feed regions. The effect of feed region is very important and cross polarization can be decreased by reducing the feed radiation. The performance of a double layer Vivaldi antenna fed by stripline and a single layer one fed by Y2Y feed are compared. The designed antennas can be used for Ultra Wideband (UWB) microwave imaging applications.
