摘要
We present a simple technique for electromagnetic (EM) simulation-based design optimization of antenna structures. Our approach utilizes a low-fidelity model of the antenna under design, implemented through coarse-discretization EM simulations. The low-fidelity model is aligned with the original, high-fidelity one using multipoint response correction. As opposed to the simple additive response correction (referred to as output space mapping), the multipoint version introduced here exploits all high-fidelity model data accumulated during the optimization process, which improves the generalization capability of the corrected model. As a result, an optimized antenna design can be obtained at a lower computational cost, which is demonstrated using two examples: a dielectric resonator antenna and an ultra-wideband stripline monopole antenna.
