摘要
为分析微波信号通过金属桁架式天线罩薄膜的传输特性,以平面波在无限大多层介质中的传输和反射为出发点,计算和分析了平面波穿透单层、多层介质时的功率传输系数、反射系数。采用了等效传输线方法,综合运用微波网络级联矩阵理论,一定程度上简化了多层薄膜传输损耗的计算,并以某金属桁架式卫星天线罩为对象,仿真分析了电磁波入射薄膜的电性能,得到了一些有意义的结论。
Based on the transmission and reflection of plane waves in infinite multilayer media,the power transmission coefficient,reflection coefficient of plane waves passing through monolayer and multilayer media was calculated and analyzed,so as to examine the transmission characteristic of me-tal truss radome film.Method of equivalent transmission line was adopted and the theory of cascading matrix of microwave network was used to simplify the calculation at a certain extent.The electrical properties of a metal truss satellite radome were analyzed with the presentation of the electrical performance parameters,whereby some significant conclusions were drawn.
