Thus dielectric-related dispersion of CPW is minimal and this is one of the main advantages of using CPW over microstrip. History of coplanar waveguide. The analytical first-order approximation to the TL model shows little deviation from the precise numerical result for the TL. As mentioned preciously, if you want to make compact circuits using narrow transmission lines, you must trade off RF loss. In addition you need to use different formulas to calculate the gemetrical dimensions such as slot or strip widths.
