摘要
采用保角变换和部分电容法 ,导出了耦合共面波导奇偶模单位长度电容及其特性阻抗的解析表达式 .数值结果与利用其他方法分析椭圆耦合带线、三带线耦合共面波导和矩形屏蔽耦合共面波导的结果吻合得较好 。
Two new cylindrical shielded coplanar coupled waveguides (CSCCPWs) were proposed. Simple analytic formulas for odd and even mode capacitances per unit length and characteristic impedances for those two coupled structures were derived using conformal mapping method and partial capacitance technique. The numerical results are in good agreement with those obtained by other authors. This shows reasonableness and exactness of the presented structures and analytic method.
