Model Correction and Optimization Framework for Expedited EM-Driven Surrogate-Assisted Design of Compact Antennas

Abstrakt

Design of compact antennas is a numerically challenging process that heavily relies on electromagnetic (EM) simulations and numerical optimization algorithms. For reliability of simulation results, EM models of small radiators often include connectors which—despite being components with fixed dimensions—significantly contribute to evaluation cost. In this letter, a response correction method for antenna models without connector, based on a so-called network unterminating concept, has been proposed. Unterminating allows for obtaining electrical parameters of the connector embedded in the EM antenna model. They can be then utilized to refine the reflection characteristics of the EM antenna model without connector. The refined model has been optimized using a novel trust-region-based method. It exploits information gained from unsuccessful iterations to improve accuracy of the model and prevent premature convergence of the algorithm. The proposed design approach has been demonstrated using two antenna structures and compared to benchmark algorithms.
