The overlapped-subarray technique makes it possible to obtain very low sidelobes ofthe solid-state phased-array antenna and reduce the number of DBF channels so that thephased-array antenna can perform very well. The overlapped subarray can be easilyformed on the array face by using the multiple-beam feeder and the space-feedtechnique.This paper discusses the general features of this kind of antenna, makes a de-tailed theoretical analysis of its radiation characteristics and derives some useful design for-mulas....
