AN ITERATIVE SCHEME SOLUTION FOR THE ANALYSIS OF PRINTED ARRAYS

This paper presents an iterative scheme for the solution of the large matrix equations arising in the full-wave electromagnetic analysis of printed antenna arrays. The proposed technique is based on the Jacobi decomposition of a matrix linear equation which allows the constructio n of an iterative solution scheme. It is demonstrated that the couplin g of the iterative process to a convergence accelerator algorithm guar antees convergence, even when ill-conditioned problems are treated. Nu merical implementation is discussed, and the advantages of the propose d technique are illustrated through the analysis of a practical slot f eed patch away. (C) 1997 John Wiley & Sons, Inc.
