| Abstract(in English) | We propose a new method for determining the optimum antenna design by combining a genetic algorithm (GA)and Improved circuit theory(ICT). Without having to provide initially the basic structure, the GA-ICT method automatically obtains the desired design requirements such as electrical characteristics, antenna shape, and size utilizing an optimization evaluation function. Since the evaluation function is constructed based on the weights derived from the characteristics, it may become difficult to obtain all design requirements at the same time due to the nonlinear characteristics of each item. To overcome this problem, we introduce a vector evaluation method to GA-ICT that generates in parallel calcuations different individual sets. The evaluation functions have different weights to generate different chromosomes that satisfy other design conditions in the first parallel GA operation and the sets are merged in the next GA operation. By applying this vector evaluated GA-ICT to the sector antenna down sizing problem, we were able to downsize the multi-sector monopole Yagi-Uda array antenna(MSMPYA)by 70%. |
