ACCELERATED ANTENNA DESIGN METHODOLOGY EXPLOITING PARAMETERIZED CAUCHY MODELS

We propose an optimization methodology suitable for the design of various antenna structures. This methodology includes a rapidly-converging iterative scheme. In each iteration stage, the algorithm generates a parameterized Cauchy model using the available results from previous iterations. Optimization is then applied to this Cauchy model to obtain better design parameters that are also used in enhancing the accuracy of the model. This cycle continues until the speciflcations are met. In addition, this on-the-∞y technique produces an analytical model of the behavior of the antenna structure. Sensitivity and tolerance analysis can thus be e-ciently carried out without the need for further costly electromagnetic simulations.
