Abstract: A new application of genetic algorithms (GAs) for feed point optimization of a coaxial probe fed E-shape microstrip patch antenna is presented. The GA shows excellent results for finding the best feed point in a given antenna structure. The method of moments is used in this paper, employing Rao-Wilton-Glisson basis functions. The simulation results show that the E-shape microstrip patch antenna performs well at similar to 2.11/GHz with the minimum return loss of approximately -17.1 dB. (c) 2006 Wiley Periodicals, Inc.
