Chapter 2: Simulation-Driven Antenna Design

In this chapter, formulation and challenges of antenna design are discussed from the perspective of simulation-driven optimization. The emphasis is put on explaining the role of computer simulations in modern antenna engineering, formulating the design task as an optimization problem, as well as introducing the notation used throughout the book. Furthermore, we outline typical antenna design objectives. We also provide a brief discussion of computational models utilized in antenna optimization with the emphasis on a distinction between high- and low-fidelity electromagnetic (EM)-simulations, the latter utilized as auxiliary models to speed up the EM-driven design process. The chapter is concluded with a discussion of the challenges related to simulation-based design of antenna structures.
