This paper provides a solution to the problem of matrix synthesis of wideband antenna array on the basis of the extended generalized energy functional subject to the restrictions on the shape of the radiation pattern. To account for the linear constraints on the vanishing of the radiation pattern in a given direction when the problem of synthesis of the constraint matrix is formed, taking into account the properties of the synthesized wideband antenna array. To determine the optimal vector currents, maximizing the energy functional defined within the constraints theorem is used for extreme properties of the characteristic properties of the beam Hermitian forms. Numerical examples of the synthesis of wideband antenna array. The proposed approach to solving the problem of synthesis of broadband antenna array to integrated generalizes the method of matrix synthesis and antenna array can solve optimization problems with the operating frequency band Rs. Advanced generalized energy functional is given with respect to the Hermitian forms and, therefore, apply to it the theorem on the extreme properties of the characteristic properties of the beam Hermitian forms. The main advantage of the proposed solution of the synthesis broadband antenna array is invariant vector of complex amplitudes of currents maximizing functionality with the predetermined linear constraints in a predetermined frequency band. The simulation results for a rectangular antenna array omni directional radiators with a number of radiators have shown that when the operating frequency(across the frequency band) provided in a predetermined direction forming a deep dip to - 90 dB.
