提出了确定非对称槽宽多层圆柱共面波导(MCCPW)特性的便于计算机辅助设计的解析公式.基于一系列保角变换,导出了计算非对称槽宽MCCPW的等效相对介电常数和特性阻抗的封闭表达式,研究了MCCPW的非对称槽宽对准静态参量的影响.所得结果表明,本文所导公式更具一般性且同样有较高精度.

Computer-aided design-oriented analytical formulas were presented for determining the charac-teristic parameters of multilayered cylindrical coplanar waveguide (MCCPW) with asymmetrical slot widths. Closed-form expressions were derived for evaluating the effective relative dielectric constant and characteristic impedance by using a sequence of conformal transformations. The effect of the asymmetric slot widths of MCCPW on the quasistatic parameters were investigated. And comparisons were also made between the present results and the results available in the literature for the cylindrical CPW. The derived formulas show good accuracy.
