Vector evaluated GA-ICT for novel optimum design method of arbitrarily arranged wire grid model antenna and application of GA-ICT to sector-antenna downsizing problem

摘要

This paper proposes the Vector Evaluated GA- ICT(VEGA-ICT), a novel design method that employs the Ge- Netic Algorithm(GA)to obtain the optimum antenna design. GA-ICT incorporates an arbitrary wire-grid model antenna to de- Rive the optimum solution without any basic structure or limita- Tion on the number of elements by merely optimizing an objective Function. GA-ICT comprises the GA and an analysis method, the Improved Circuit Theory(ICT), with the following characteris- Tics.(1)To achieve optimization of an arbitrary wire-grid model Antenna without a basic antenna structure, the unknowns of the ICT are directly assigned to variables of the GA in the GA-ICT.
