A multi-cell array decomposition approach to composite finite array analysis

In this paper, we introduce a multi-cell array decomposition method applicable to complex structures with repeating features. With this method, we demonstrate that some common real-world structures can be decomposed into repeating cells for significant storage reduction, enabling us to analyze the coupling between several configurations of dual-polarized tapered-slot antenna arrays supported by a ground-plane. Measurement comparisons are presented. For brevity, we refer to this analysis technique as the multi-cell array decomposition method (multi-cell ADM).
