悬置共面波导兼有鳍线和悬置带线的优点.本文用共形变换技术分析悬置共面波导,得到严格的解,考虑有限基片情况下给出了悬置共面波导的有效介电常数,单位长度电容和特性阻抗的闭合表达.
Suspended coplanar waveguides have the advantage of both finline and suspended stripline. In this paper suspended coplanar waveguides are analyzed using conformal mapping techniques, and the exact solutions are obtained. Analytic closed-form expressions for the effective dielectric constant, the capacitance per unit length and the characteristic impedance of the suspended coplanar waveguides with finite thickness of dielectric substrate are given.
