Abstract
A simple yet robust methodology for rapid multiobjective design optimization of antenna structures has been presented. The key component of our approach is sequential domain patching of the design space which is a stencil-based search that aims at creating a path that connects the extreme Pareto-optimal designs, obtained by means of single-objective optimization runs. The patching process yields the initial approximation of the Pareto set representing the best possible trade-offs between conflicting design objectives. It is realized—for the sake of computational efficiency— at the level of coarse-discretization EM simulation model. The final Pareto front is subsequently obtained using surrogate-assisted optimization where the EM simulation data acquired at the initial design stage is reused. The proposed methodology is demonstrated using two examples of ultra-wideband monopole antennas.
