摘要
本文首先利用保角变换法分析了自由空间中的非对称共面线,得到了其严格解,然后给出了任意多层有限厚度衬底非对称共面线的有效介电常数、单位长度线电容、特性阻抗和导波波长的闭合形式的解析表达式。这些分析对微波毫米波集成电路的设计有意义。
In this paper, asymmetrical coplanar lines in free space are analyzed using confor-mal mapping techniques, and the exact solutions are obtained. Analytic closed-form expressions for the effective dielectric constant, the capacitance per unit length, the characteristic impedance and the wavelength of guided wave for asymmetrical coplanar lines with multi-layered finite substrate thickness are obtained. The analyses are useful for the (M)MIC's designs.
