Sensitivity analysis in genetic design of wire antennas

The problem of sensitivity in output results of genetic algorithms (GA), which are used for antenna design, causes the results to be unfeasible. This problem is due to variation of final objective (cost function) when the antenna has some physical variations. Moreover, these GA results are not reliable because of sensitivity of the results to segmentation changes in computer analysis. These challenges motivate us to consider these specifications in the designs. The presented paper has paid attention to this problem in Yagi-Uda antennas as an example of wire antennas.
