Optimization of Microstrip Antenna Arrays Using the Differential Evolution Method

In this paper, the application of the Differential Evolution (DE) method to realize the synthesis of radiation pattern of a linear array is discussed. The general formulation for the technique is presented. To demonstrate the application, the method has been applied to the synthesis of a four-element array composed of E-shaped patches to achieve beam steering with sidelobe level control. The patterns could be optimized after only few iterations with the proposed formulation and by including mutual coupling between the array elements.
