A new, non-iterative technique for synthesizing equispaced linear arrays with symmetric excitation is proposed. The methods is on the computation of an eigenvector of an appropriate real, Symmetric and positive-definite matrix. This technique can be used to determine, given a n complete description of the desired radiation pattern, the array excitation coefficients . These derived excitation will produce, either exactly or approximately, the wanted antenna radiation pattern, depending on its complexity and the number of my elements. A number of design examples are presented to illustrate the practicality and the potential of the proposed method.
