A planar topology of multifunctional C-X band wide-scan array is analyzed, based on the class of the aperture-coupled stacked patches. Performance is aimed at achieving both wide-band and wide-scan capabilities. The theoretical and the technological aspects that affect correct design and effective realization of the array structure are addressed. In particular, possible improvements of the active reflection coefficient behaviour are analysed by suitably acting on the geometry of the elements.
