The Application of Genetic Algorithms(GAs) on the Design of Asymmetric Waveguide Slotted Antenna

Genetic algorithms(GAs) are successfully applied to the optimization of the asymmetric ridged wave-guide slot antenna design.The paper discusses the design of the fitness function in the application in details.The design procedure can be divided into two steps: firstly,the amplitudes of the slots are used to optimize elementary unit.Secondly,the methods combined with the dynamic coupling among the slots were applied in the optimization of the offset of the slots and the both groove depth of the ridged wave-guide.As a result,a(1×10 elements) slot array is designed out and is used to show the validity and accuracy of the GAs.
