Abstract :
In this article the method of antenna array synthesis according to the given amplitude directivity pattern is generalized on the case of antenna system of parallel cylindrical radiators which centers are located on one plane. It´s used more precise formulation of problem which takes into account the mutual coupling of radiators. The synthesis problem is formulated as a problem of minimization of smoothing functional and is reduced to finding of voltages distribution from the system of nonlinear integral equations of Hammerstein type. The numerical results of synthesis of different types of the given amplitude directivity patterns are obtained.
