摘要:
<正> 一、引言带状传输线的理论和应用已有三十余年的历史。早期关于非屏蔽(接地板无限宽)带状线和薄导带(厚度趋于零)屏蔽带状线的分析,多采用复位函数的保角变换技术,导出其特性阻抗的解析表达式。对于厚导带的屏蔽带状线,当导带置于正常的中心位置时又称矩形同轴线,也已经借助施瓦兹变换导出了特性阻抗的严格解;但当导带偏离中心位置、或不平行于外导体边界时,只能采用各种近似方法求解。Brackelmann曾用分区本征函数展开法分析导带二维偏位的屏蔽带状线,给出有关的阻抗曲线,但读数标度过于简略。有限差分和有限元法都可用于分析这些传输线,然而近年来迅速发展的边界元法具有计算量
Abstract:
The characteristic impedances of shielded strip-line are analized by the Boundary Element Method (BEM). The principle and the flow chart of corresponding program are shown. The curves of the characteristic impedances of shielded strip-line with arbitary thickness and position of strip, and the evenmode characteristic impedances of shielded coupled strip-line have been given. By these data the analysis of structure tolerances may be performed.
