Analysis of Homogeneous Coplanar Strip Line

Abstract

The goal of this work is to introduce a new, maybe complicated butin the final result mathematically simplest model of the coplanar stripline (CPS). In contrast to the usual method based on ellipticalintegrals the simplest circular inversion is applied. The mainadvantage is that our solution is mathematically less complicated butits accuracy is a little bit lower. The maximal error of the modeldescribed lies within the restricted interval between -3% and 3%.Nevertheless the final formula is useful for the practical engineeringapplication.
