Abstract

Microstrip circuit elements and discontinuities are analyzed by an efficient moment method procedure that utilizes closed-form Green´s functions and exploits symmetries to fill the moment matrix efficiently. Reciprocity is applied to derive a new formula for computing the “voltage” of a point on the microstrip surface, which is used, along with the computed currents, to calculate Z-parameters of the circuit elements. Computed circuit parameters are compared with results obtained independently by the least-squares Prony´s method, and with measurements
