Rapid multi-objective design optimization of ultrawideband (UWB) multiple-input-multiple-output (MIMO) antenna is presented. Our approach allows for finding the best possible design trade-offs (a so-called Pareto set) with respect to the two objectives: minimization of the reflection coefficient and reduction of the antenna footprint. Computational efficiency is obtained by using variable-fidelity...
A methodology for fast multi-objective antenna optimization is presented. Our approach is based on response surface approximation (RSA) modeling and variable-fidelity electromagnetic (EM) simulations. In the design process, a computationally cheap RSA surrogate model constructed from sampled coarse-discretization EM antenna simulations is optimized using a multi-objective evolutionary algorithm. The...
