Evolutionary Techniques for EM Device synthesis

This paper demonstrates the use of evolutionary methods for synthesis of antenna. Microstrip line fed rectangular microstrip antenna for WLAN band is the example antenna. Analysis of the synthesized antenna for 5.9 GHz uses CST microwave studio for simulation and compares its result with measurement on a prototype. A comparison of genetic algorithm (GA) based synthesis with that of differential evolution (DE) indicates the later as a better choice.
