摘要：

A knowledge of the net inductance of the ground plane can aid in the analysis and investigation of printed circuit board emissions. In this paper, we present a method, based on the concept of partial inductance, to determine the net inductance of the ground plane associated with a microstrip line, This method is based on a previously derived expression for the current density on the ground plane, We show calculations for the net, self-partial, and mutual-partial inductance of the ground plane for various trace geometries of practical interest, We also illustrate how the classical transmission line inductance of a microstrip line can be obtained from the concept of partial inductance, Comparisons to different experimental results are also given.
