Abstract :
An open microstrip line with finite strip thickness is numerically analyzed by the Green´s function technique. The normalized longitudinal current distributions are systematically obtained for the cases of various shape and thickness ratios in the quasi-TEM approximation. The obtained results are illustrated in figures for three surfaces of the thick strip conductor, that is, the lower, side, and upper surfaces. The closed-form expressions are obtained for the normalized longitudinal current distributions by taking a best fit to theoretical results
