Closed-Form Expressions for the Current Densities on the Ground Planes of Asymmetric Stripline Structures
Christopher L. Holloway
In this paper, closed-form expressions for the current density on the ground planes of an asymmetric stripline structure are derived. The derivation utilizes image theory in order to obtain a suitable quasistatics Green''s function for this asymmetric geometry. It is demonstrated that the results presented here reduces to the previously derived case of an symmetric stripline geometry, which was obtained from a different approach. By allowing one of the ground planes to move to infinite, the stripline becomes a microstrip line. Under this condition, it is also demonstrated that the results presented here reduce to the previously derived result of a microstrip line ground plane current distribution. As expected, it is illustrated that the current densities on the ground planes of an arbitrary asymmetric stripline are bounded by the current distribution of a symmetric stripline and that of a microstrip line.
