EM SIMULATION OF PACKAGED MMIC AND MICROSTRIP ANTENNAS USING "MICROWAVE EXPLORER"

Abstract

A moment method solution is presented for the full-wave electromagnetics analysis of multilayered planar structures of arbitrary shape. The mathematical formulation is based on the spectral domain integral equation and the Galerkin's testing procedure. The method is applied to shielded MMIC as well as radiating systems in the open environment. The inclusion of vertical current elements in the solution enables the method to analyze structures with vias and air bridges in both packaged and open environments Since a periodic structure approach is used in the formulation, extension to the analysis of infinite and finite antenna arrays becomes rather straightforward. Simulated results, obtained from our electromagnetic simulator "Microwave Explorer," are presented and compared with the available data to demonstrate the versatility and the accuracy of the method The numerical results presented include S-- parameters and farfield data.
