“…In antenna implementations, they have found several branches to deal with, such as, for example [1,2]: in antenna arrays, for signal-and power-control; in radar, for targets detection and recognition; in microwave devices, for design and optimization; and even in computational electromagnetics, for reducing the number of operations in some kind of calculations. In antenna array design, several works by Christodoulou, Southall, O'Donnell, and Mailloux (some of them with collaborators) are of concern [2,4]. The tools presented by those authors are based on real-valued ANNs, which, in principle, are the ones initially defined by the pioneers of that field (the first work about ANNs is attributed to McCullough and Pitts, in a paper dated 1943) [1].…”
