Behavioral Models for the Cosimulation and Optimization of Active Electronically Scanned Arrays

Active Electronically Scanned Arrays are versatile antenna solutions when high reconfiguration capabilities are required. However, they remain difficult to optimize due to their important degrees of freedom and their nonlinear components, sensitive to antenna impedance variation. This contribution describes the use of behavioral models for both nonlinear components and antenna radiating elements, allowing large array cosimulation and opening paths to several optimizations.
