Abstract
This distributor relates to radar antennas. It is used notably for making multiple-beam antennas. It is of the optical Blass matrix type. It has a horn-shaped guide with two energy leading-in central strips that radiate directly in space by means of excitation obstacles which are cylindrical studs arranged in pairs on the inner surfaces of the side walls to obtain the desired directivity. By means of this distributor, it is possible to simultaneously achieve sum and difference patterns or again different directions of aim.
