摘要：

In this work, a computationally efficient antenna modeling technique. Our methodology is a two-stage approach is present. In the first stage, a Cauchy-based approximation model is constructed using coarsely discretized full-wave simulation. The accuracy of this model is improved using a space mapping (SM) approach. A limited number of high-fidelity antenna simulations are used in the SM phase. We show that our approach obtains a modeling accuracy comparable to that provided by direct Cauchy approximation of the high-fidelity electromagnetic simulation data. The computational cost is, however, much lower. We successfully illustrate our approach through a number of antenna modeling examples. (C) 2011 Wiley Periodicals, Inc.
