  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.
