A Network Reduction Technique for Microstrip Three-Dimensional Problems

A method is presented for obtaining the equivalent capacitances of microstrip discontinuity structures. The method of formulation and solution is based on the resistive network reduction technique. The formulation results in a matrix eigenvalue problem and permits us to obtain more accurate results with a relatively short computer time requirement. Numerical results for a variety of discontinuity configurations are presented and compared with results published by other investigators. Excellent agreement has been obtained in all cases.
