An improved version of the variable-fidelity optimization technique for the simulation-driven design of microwave structures including antennas is presented. It exploits a set of electromagnetic(EM)-based models of increasing discretization density that are sequentially optimized with the optimum of the “coarser” being the initial design for the “finer”. The final design is refined using a polynomial-based approximation model constructed from the coarse-discretization simulation data. The… CONTINUE READING

Key Quantitative Results

  • The coarse-discretization models are optimized using a novel algorithm that allows us to reduce the overall design time by up to 50% when compared to the original version of the method.
  • The coarsediscretization models are optimized using a novel algorithm that allows us to reduce the overall design time by up to 50% when compared to the original version of the method.
  • Based on two broadband antenna examples we demonstrate that the computational cost of the design process can be reduced by up to 50% when compared to the original approach [12], without compromising the quality of the final design.
