PCB Stripline Impedance Calculator
A stripline transmission line is similar to a standard stripline transmission line, but has round conductors. Modeling approximations can be used to understand the impedance of a stripline transmission line.
Description
A wire stripline is constructed with a round conductor suspended between two ground planes. The conductor and ground planes are separated with a dielectric. This calculator assumes the distance between the two reference planes to be an equal distance.
Microstrip Transmission Line Models
The impedance Z0 of a transmission line consisting of a circular signal conductor having a diameter d and centered between parallel ground planes separated by a distance h is given by:
Eq. 1
Impedance calculation
Microstrip impedance shall be calculated according to above Eq. 1
