Application of Genetic Algorithm for Computer-Aided Design and Optimisation of Microwave Circuits

Abstract

The application of genetic algorithm for computer-aided design and optimisation of microwave circuits is presented using the example of three section Quarter wave transmission line transformers. The circuit chosen In this paper is a classic example to compare different optimisation algorithms[1]. Two different optimisation methods gradient search algorithm and genetic algorithm have been used for the optimisation. It has been found that the optimisation method based on genetic algorithm is very robust for the optimisation of microwave circuits.
