Abstract: Invention of electronic cluster scanning method for Geodesic Sphere Phased Array Antenna System that is simultaneously faster cheaper and simpler is presented in this patent. This invention is based on recognition and skillful exploitation of multi-level symmetry properties inherent in the truncated icosahedron based geodesic sphere phased array antenna structure described in an earlier invention. The cluster scanning method employs cluster switching with limited angle electronic scanning involving inter-twined hexagonal sub-array centered clusters and pentagonal sub-array centered clusters.
