equivqlent circuit of coupled transmission line

dear all,

can anybody help me to find out an equivalent circuit of coupled transmission line(microstrip),my system is a four layer board with lines at top nd bottom layer with via connecting these two

Hello Anu,

You can extract the coupled transmission line model using Sonnet, see the below topic "Extraction of Transmission Line Models "
Sonnet's coupling matrix extraction capability provides transmission line models for multi-conductor 2.5D transmission lines. Any number of transmission lines may be modeled, and may exist on or within any number of dielectric layers.
