| 摘 要： | 设计了一个毫米波Rotman透镜天线,该天线也是一个同时多波束天线。用Rotman透镜作为馈电网路,运用准光学技术替代大量移相器,获得同时多波束扫描,并且使电路变得简单,减少了体积和重量。包括馈电网络在内的整个天线系统采用微带来实现,并且使用Ansoft Ensemble仿真软件进行辅助设计,仿真结果表明,该天线可以实现大角度窄波束扫描。

| Abstract: | A millimeter-wave Rotman Lens antenna,used as a multiple-beam antenna,is designed in this paper.Rotman lens,using quasi-optical technology,is used as a feed network of millimeter wave antenna,which would replace a lot of phase shifters.In this way,we can provide multiple beam scanning.Further more,it has simple circuits,small volume,light weight and can be easily designed.The antenna system is realized with microstrip.Simulations have shown that this antenna can achieve narrow beams and wide-angle scanning. |
