ABSTRACT:
A phased array antenna system divides the array into a plurality of subarrays that are driven by fine phase shifters with each subarray having a plurality of antenna elements driven by respective coarse phase shifters that are preferably MEMS coarse phase shifters having low weight and low cost and are infrequently used for improved reliability for selecting a coarse beam coverage area while the fine phase shifters are used to scan a high-gain antenna pattern within the selected coarse beam coverage area. Two-bit MEMS phase shifters are used to scan the beams from subarrays to various coverage areas within the required antenna field of view, thereby providing coarse beam steering for an array.
