This letter shows that the synthesis of coplanar waveguides with finite substrate thickness can be obtained by simple numerical solution from the exact quasi‐static formulae of the characteristic impedance using bisection method The novelty of the method is that accurate synthesized values compared to those from curve fitted formulae are obtained. Moreover, sophisticated numerical techniques are not required. The method can be extended to various other forms of coplanar waveguides and coplanar strips for which curve fitted design formulae may not be available.

共面波导的数值合成

这封信表明，可以使用二等分法，通过精确的特征阻抗准静态公式，通过简单的数值解法，获得具有有限衬底厚度的共面波导的合成。该方法的新颖之处在于，与通过拟合曲线得到的精确合成值相比，合成值更精确获得公式。而且，不需要复杂的数值技术。该方法可以扩展到共面波导和共面条的各种其他形式，对于这些形式，可能无法获得曲线拟合的设计公式。
