Abstract
In this paper, we study an electromagnetic optimization technique using Taguchi's method and apply it to circular antenna array (CAA) design. Taguchi's method was developed on the basis of the orthogonal array (OA) concept, which offers systematic and efficient characteristics. The newly proposed idea is the implementation of Taguchi optimization method for CAA of order 10, 16 and 24 respectively. The optimization procedure is then used to provide an optimum set of weights for different CAAs. Obtained results show that the desired radiation pattern with optimum sidelobe level (SLL) reduction is successfully achieved. Compared to traditional optimization techniques and well-known algorithms (Particle Swarm Optimization (PSO), Genetic Algorithm (GA), and Firefly Algorithm (FA)), Taguchi's method is easy to implement and efficient to reach the optimum solutions.
