The inability to derive closed-form analytical solution to Maxwell’s equations under various complex interface and boundary conditions is overcome by Computational Numerical Technique. Computational Electromagnetics offers the possibility for modeling to be undertaken within a significantly shorter time than it would be necessary for building and testing the appropriate prototype via experimental procedures, thus reducing the cost associated with the design process. This study describes an accurate and computationally efficient technique for the analysis and design of boxed microstrip circuits. The theoretical derivations are based on the Electric Field Integral Equation (EFIE) that involves the formulation of Green’s functions that accurately describe the boxed structure, and rooftop basis functions to approximate the current on the patches. The simulated results compare favourably with experimental results.
