Optimization of phased arrays integrated with FSS and feeding elements based on parametric models Optimization of Phased Arrays Integrated with FSS and Feeding Elements based on Parametric Models

Abstract In this paper, we introduce a general framework to efficiently optimize phased array antennas integrated with Frequency Selective Surfaces (FSS) and feeding elements. The framework consists of two main parts: the first being parametric models that enable fast evaluation of the full-wave problem for a range of frequency, scan angle and geometry parameters. The second part consists of a number of optimization methods to generate an optimum set of geometry parameters by minimization of a penalty function. Results are shown for parametric models and the optimization of various examples
