The results of numerical simulation and experimental modelling of a multi-disk slowing structure excited by a two-dimensional planar array antenna of circular waveguides are presented. The geometrical parameters of the array structure with the flat-topped element pattern, required to suppress the array grating lobes when beam scanning, are also determined
