Results of a computer design of  multi-channel cluster radiator on the base of array of unequal coupled waveguides inside EBG structure are presented. Numerical modeling of a scattering matrix is executed by a method of finite elements. Amplitude and phase distributions in output aperture are calculated via S-matrix coefficients. Radiation patterns and their dependences on parameters of array and frequency are investigated by the Kirhgoff method. The sample of cluster radiator is fabricated. Radiation patterns of the sample are measured at three frequencies. Comparison of results of numerical modeling and data of physical experiment is presented.
