Linear Antenna Array Synthesis Using Taguchi´s Method: A Novel Optimization Technique in Electromagnetics

We describe a new global electromagnetic optimization technique using Taguchi´s method and apply it to linear antenna array design. Taguchi´s method was developed on the basis of the orthogonal array (OA) concept, which offers systematic and efficient characteristics. This paper illustrates the implementation procedure of Taguchi´s method in electromagnetic optimization problems. The optimization procedure is then used to design two linear antenna arrays with specific array factor requirements. Obtained results show that the desired null controlled pattern and sector beam pattern are successfully achieved. Compared to traditional optimization techniques, Taguchi´s method is easy to implement and efficient to reach the optimum solutions
