Abstract :
Overlapped subarrays are a special class of arrays that enable engineers to produce radiation patterns with low sidelobe and grating-lobe levels over a wide bandwidth. Their complex feeding structure has prevented their use until recently. This paper presents a tutorial on overlapped subarrays, and reviews recent work on this technology.
