摘要

Accelerated simulation-driven design optimization ofantenna structures is proposed. Variable-fidelity electromagnetic(EM) analysis is used as well as the trust-region framework withlimited sensitivity updates. The latter are controlled by monitoringthe changes of the antenna response gradients. Our methodology isverified using three compact wideband antennas. Comprehensivebenchmarking demonstrates its superiority over both conventionaland surrogate-assisted algorithms.
