The geodesic dome phased array antenna for satellite control and communication - subarray design, development and demonstration

In this paper we present the design, development and demonstration of an L/S band subarray - a basic building block of a geodesic dome phased array antenna. As previously reported, the geodesic dome array is a highly effective, multi-function, low cost spherical phased array antenna that provides hemispherical coverage. The antenna consists of a number of near-equilateral triangular, planar subarrays arranged in an icosahedral geodesic dome configuration. This novel architecture design preserves all the advantages of a spherical phased array antenna while its fabrication is based on well-developed, easily manufacturable, and affordable planar array technology. The antenna is used for simultaneous, full-duplex communication and control of multiple satellites, and for air/space surveillance over the entire sky.
