Abstract
A geodesic sphere phased array antenna system, capable of scanning the entire omni-directional communication space and comprising substantially equilateral triangular planar subarrays of antenna elements arranged in a geodesic sphere configuration. Icosahedron, one of the five regular solids and truncated icosahedron, one of the fifteen semi-regular solids are the preferred basis of the geodesic sphere phased array construction. The entire communication space is considered as subdivided into a large number of smaller cells and corresponding to each such cellular communication space, a contiguous set of the subarrays is energized and electronically phased to scan the cellular space. Another contiguous set of subarrays is energized and electronically phased to scan another cellular space in a similar manner resulting in limited angle scanning requirements which permit the basic antenna elements to be connected in a cluster as a unit building block to which transmit/receive signal distribution and processing means are connected resulting in lower costs in deployment, operation and maintenance.
