A technique for expedited redesign of UWB antennas for various substrates is presented. Our approach exploits an inverse surrogate model constructed for several reference designs optimized for selected values of the substrate permittivity. The surrogate is set up at the level of coarse-discretization EM simulation model of the antenna and, subsequently, corrected to provide prediction at the level...
A computationally efficient simulation-driven technique for design optimization of antennas is described. Our approach exploits a recently introduced shape-preserving response prediction (SPRP) technique as well as coarse-discretization EM simulations as the low-fidelity antenna model. SPRP allows us to estimate the outcome of the high-fidelity EM antenna simulation, e.g., its S11 versus frequency,...
