Afmfract ―In this paper, closed-form expressions are presented which model the frequency-dependent even- and odd-mode characteristics of parallel coupled nderostrip fines with hitherto unattained accuracy and range of valWy. They include the effeetive dielectric constants, the characteristic impedances using the power-cument formulation, as well as the open-end equivalent lengths for the two fundamental modes on coupled microstrip. The formulas are acenrate into the millimeter-wave region. They are based on an extensive set of accura
