Abstract :
The accuracy of various mathematical models for the prediction of the capacitance and characteristic impedance of a single-conductor microstrip is investigated. Comparison between experimental and modeled results indicates that purely empirical models are sometimes the most accurate over a limited range of parameters. When various mathematical models are compared to calculations done by the boundary-element method, Wheeler´s formulas (1977) are found to be very accurate. Various other mathematical models are studied and the source of discrepancies between experimental results and exact mathematical models is discussed
