Abstract: Design optimization of antennas is challenging, in most cases it
involves electromagnetic (EM) simulations. High-fidelity simulation is
computationally expensive and, therefore, employing EM solver in an
optimization loop may be prohibitive. In this paper, we discuss optimization
approaches that exploit coarse-discretization EM simulations as a low-fidelity
model, and allow us to locate the optimum design of the antenna at a low
computational cost. Some practical issues, including the importance and
selection of the model fidelity are also discussed.
