Genetic algorithms (GAs) are successfully applied to the optimization of microstrip antenna design.This paper discusses some basic problems in this application thoroughly
such as the definition of genetic series
the combination of GAs and method of moment
the design of fitness function and the selection of control parameters.Using GAs
a wide band microstrip antenna is designed
the bandwidth expands from 5% to 16.6%.A dual frequency antenna is also optimized.The ratio of these two frequencies is 1∶1.31 and both frequencies have the same linear polarization.
