Abstract
In previous work, a closed-form expression for the current density on the ground plane of a microstrip line was presented, In this paper, we show how this formula for the current density is used to derive an ex pression for the internal inductance associated with the ground plane, Results are presented for different geometries that illustrate when t he internal inductance of the ground becomes comparable to the externa l inductance of the microstrip line, We also illustrate that the integ rals needed for the internal inductance calculation can be used to dev elop an expression for the conductor loss associated with the ground p lane.
