- Title
Near Field to Far Field Conversion for an Infinite Ground Micro-Strip Trace Using Genetic Algorithm.

- Abstract
In this paper, an efficient combination of the near field to far field (NF-FF) transforma-tion and the genetic algorithm (GA) is suggested for investigating of a microstrip trace on an infi-nite ground plane. Parameters of a set of ideal electric and magnetic dipoles are estimated by GA based on finite samples of near field data in the radiation region. Then, the far field pattern is de-termined, using the electromagnetic (EM) fields of equivalent ideal dipoles. The commercial software Ansoft High Frequency Structure Simulator (HFSS) is used for both, computing the near field data and validation of the proposed method. In addition, the influence of number of dipoles on the convergence rate is studied.
