On the Design of Next Generation Phased Array Antennas - Methods, Architectures, and Trends

The study of innovative methods and architectures for the design of next generation phased array antennas is still a research topic of high interest in the antenna academy and industry communities. The design of trade-off solutions balancing between costs/complexity and performance through non-uniformly spaced or clustered arrays is crucial for many forthcoming phased array applications. In this context, a review of the last methodological and architectural advances is reported, focusing on the design of irregular highly modular phased arrays.
