摘要: 本文首先利用保角變換法分析了自由空間中的非對稱共面線,得到了其嚴格解,然后給出了任意多層有限厚度襯底非對稱共面線的有效介電常數(shù)、單位長度線電容、特性阻抗和導(dǎo)波波長的閉合形式的解析表達式。這些分析對微波毫米波集成電路的設(shè)計有意義。

Abstract: 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. -
