Modern-day wireless systems are compact and powerful, the hardwareHardware ecosystems for supporting these wireless subsystems also would be electrically compact. This indicates that most of the antenna designs required for modern-day devices cannot be solved analytically, indicating a need for full-wave solvers. This chapter delves into the various tips and tricks that could be used to accelerate the design process in the full-wave solver. The chapter begins with a detailed design flow of a generic antenna design problem to be solved using full-wave solvers. Various examples of antenna topologiesTopology are discussed, followed by the concept of rough simulationsSimulation. A detailed account on tuningTuning and optimization of antennas for the desired specifications is presented in this chapter. A comprehensive discussion on the choice of hardwareHardware in the context of antenna designs in the full-wave solver is also included in this chapter.
