摘要
简要介绍一种低成本铁电透镜相扫天线的工作原理及其基本特点。利用有限元方法对铁电介质加载波导移相器进行了分析,给出了计算结果,并通过一个四级阻抗匹配的铁电移相器设计实例讨论了铁电移相器设计中几个值得注意的问题。
In this paper, the operating principle and basic characteristics of a low-cost ferroelectric-lens phase-scanning antenna are briefly introduced. A ferroelectric-loaded waveguide phase shifter is analyzed using finite element method. Some calculating results of the phase shifter are given. In addition, several noteworthy problems in the design are discussed taking an example of a 4-stage impedance-matched ferroelectric phase shifter.
