Investigation of Iterative Techniques for Synthesizing of the Array Factor of the Antenna Arrays

Abstract: In this essay, several iterative techniques are investigated for synthesizing of the array factor of the antenna array. These iterative techniques include Richardson method, Jacobi method, Gauss-Seidel method, Successive-over relaxation (SOR) method. It is shown that these iterative techniques can be successfully applied to synthesize of the array factor of any arbitrary linear, planar, or even ring arrays. Traditionally, least square method (LSM) is used for this purpose. However, LSM cannot be directly applied for any practical arrays. In other words, LSM is not a general approach, and it should be mixed with other techniques to find the magnitude and phase of the excitation coefficients of each element of the under-studying arrays. Obtained results show that the proposed method, offers considerable improvements for this target.
