RESUMO

The synthesis of radiating elements of the diffraction antennas is reduced to providing a required amplitude and phase distribution of the field across the aperture. The field distribution is formed by the "dielectric waveguide-grating" system with satisfying a number of additional requirements associated, basically, with minimizing the amount of loss in the elements of the feeding section and optimizing the antenna radiation efficiency and accounting the factor of possible phase distortions. Rather difficult problems that are faced in this case are solved within the frame of an approach that effectively use the possibilities of both experimental and theoretical methods. Specific features of applying this approach to constructing linear diffraction gratings on the basis of ridged dielectric waveguides are considered in this paper.
