In the accessible literature is applied simplified calculation
methods for coupled microstrips, as give a fair decision of the
characteristic impedances within 10-20% accuracy. In this report
it is succeeded to appear calculation methods that give the
desired exactly calculations of differential mode impedance
(identical to 2x odd mode impedance) and commom mode impedance
(identical to 1/2x even mode impedance). The conformal mapping
with Schwarz-Christoffel formula give no possibility for the
inverse functions for a synthesis optimization. For that reason
there is calculated figures, who can be used for stipulation of
strip dimensions within 4% precision, referred to produced coupled
microstrips and measured impedances. The report is initiated with
exactly calculation of impedances for coplanar strips and
microstrips, because these calculations apply to the calculations
of coupled microstrips.
