Efficient array synthesis of printed arrays including mutual coupling

An efficient approach for array synthesis including the effect of mutual coupling is presented. The method is based on an iterative convex optimization scheme and on a fast full-wave simulation technique. The embedded element patterns (EEP), obtained by full-wave simulation at each iteration of the convex optimization, are exploited to take into account the mutual coupling. The final results, therefore, not only satisfy the pre-defined constraints but also guarantee the performance of the array. Numerical results of linear focused beam arrays are presented to show the effectiveness of the approach.
