Multi-Layer Sub-Array Overlapping

Contiguous sub-array overlapping is investigated for multilayer sub-arrays. The structures are implemented in multiple layers to realize complex sub-array overlapping with a smaller number of crossovers. It is shown that complex sub-array schemes, which might be impossible to realize in one layer, can be implemented in several layers with less complication. The computed results of array factors and Full-wave simulation results are presented. The Full-wave results are acceptably compatible with design computations.
