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.
