Efficient and Effective Synthesis of Large Arrays for 5G and Beyond

In this contribution we will discuss the synthesis of very large arrays, that are going to become a key technology of 5G and beyond communication systems. By means of a slightly improved version of IDEA (Inflating Deflating Exploration Algorithm), we demonstrate the ability to synthesize very sparse arrays, with a strong reduction of the number of control points with respect to a classical equispaced array radiating a beam with the same specifications.
