以数值模式匹配-有限元法(MM/FEmethod)对自行研制的吊舱式机载干扰机收发天线系统中的隔板式圆极化器进行了深入分析研究,建立了此种圆极化器的精确分析模型,在此基础上对其参数进行了精确的计算,绘制出“轴比/频率”和“驻波比/频率”分布图,所得结果与实测数据相吻合.

In this paper, by using the mode matching and finite element hybrid method(MM/FE Method),the septum polarizer which was used in the antenna system in the airborne nacelle jammer designed by ourselves is studied. Furthermore, a precise analysis model is given. On the basis of the model, we compute the parmeters of the polarizer accurately, and get the plots of the axial ration VS frequency and the VSWR VS frequency, the result demonstrated a good agreement with the test data.
