Wideband Subarray Systems: Evolution of a Research Area

Abstract

This paper discusses developments in the technology of transform-fed wideband scanning arrays. These antennas were introduced over 40 years ago, and proposed for a large number of scanning applications, but because of poor efficiency and high cost, have not found application in fielded systems. Recent technological innovations including MEMS phase shifters and digital beamforming have re-focused attention on these systems, which for many applications remain the most viable array architecture for large wide band arrays.
