Introduction
Coplanar traces are common in printed circuit boards. Coplanar traces where one trace is the signal and the
other trace is the return path apply to this inductance calculator.
Wire Loop Inductance Description
The inductance of the coplanar trace calculation requires 4 variables:
W - Trace Width
S - Trace Seperation
L - Trace Length
μr - relative Permeability
This structure requires that these spacings be uniform down the entire length of the trace.
