LARGE SCALE PHASED ARRAY STRUCTURE AND METHOD OF FABRICATION

摘要

A phased array antenna device including: a conductive ground plane body structure including a series of through apertures; a structural spacing layer having known dielectric and structural properties, for holding an active layer in a predetermined stable spaced apart relationship to the ground plane body structure; a active surface layer spaced apart from the ground plane body structure and supported by said structural spacing layer, said active layer including a series of tile components, said tile components including a number of active conductive elements formed on a non conductive substrate, said active components being interconnected to corresponding driving electronics by conductive feeds formed through said apertures.
