Use of computationally efficient method of moments in the optimization of printed antennas

Derivation of the closed-form Green's functions and analytical evaluation o f the method of moments (MOM) matrix entries have improved the computationa l efficiency of the significantly in the analysis of printed geometries. Wi th this background in mind, an extension of this efficient numerical techni que is to incorporate an optimization algorithm and to assess its potential as a computer-aided design (CAD) tool. Therefore, we have employed the Gra dient search and Genetic algorithms, in conjunction with the electromagneti c (EM) simulation technique, to a number of representative examples of inte rest.
