Popis: | An efficient technique for improving the accuracy of the domain Green's function method (DGFM) for the analysis of large finite antenna arrays with strong mutual coupling, is presented. The technique employs rigorous method of moments (MoM) analysis on strongly-coupled local domains. All antenna elements outside a local neighbourhood are still handled according to the standard DGFM approximation. This allows for maintained accuracy in case of very high local current variations and strong mutual coupling scenarios. A further improvement is presented, in order for the technique to be accurate for antenna arrays containing passive elements. The method maintains the low memory consumption and amenability to parallelization of the standard DGFM, but with improved accuracy. |
