Cl. Holloway et Ef. Kuester, CLOSED-FORM EXPRESSIONS FOR THE CURRENT-DENSITY ON THE GROUND PLANE OF A MICROSTRIP LINE, WITH APPLICATION TO GROUND PLANE LOSS, IEEE transactions on microwave theory and techniques, 43(5), 1995, pp. 1204-1207
In this paper closed-form expressions for the current density on the g
round plane of a microstrip line are derived. The derivation is based
on a quasistatic Green's function approach, These expressions are comp
ared to both experimental and numerical values, and excellent agreemen
t is demonstrated, The loss on a ground plane for a microstrip structu
re is calculated using these expressions, and comparisons with results
from Wheeler's incremental inductance rule are made.
