The application of domain decomposition method in full-wave analysis of multi-layered aperture-coupled patch antenna

In this paper, Domain Decomposition method is applied to the full-wave analysis of multilayered aperture-coupled antenna. Compared with other methods, it can greatly reduce the computing complexity and resource requirements for splitting the problem into independently sub-problems. The paper discussed implementation of the method while combined with FDFD method in detail. Several cases include domain decomposition and different mesh resolution for different sub-domain were studied. The well agreement between our method and original FDFD method demonstrated the validity and flexibility of the method
