FIELD: radio engineering. ^ SUBSTANCE: device consists of the main and additional linear dividers (LD) located one after the other in one plane; at that, each of them is made on the basis of directional couplers (DC) combined with the first and the second main waveguides (MW) respectively of similar rectangular cross-section. Branch channels of DC have common sections of wide walls with communication elements in them with MW and are oriented at an angle to its MW. To branch channels of DC of the main and additional LD, which are connected to each other, in section between DC there installed are dielectric inserts, and at the end of each of branch channels of DC, which are combined with the second MW, there are installed matched loads. MW are made so that branch channels of the main and additional LD, which are the closest to DC input, have common sections of wide walls with their MW till they are turned through 90-, where =015 in H plane and oriented to them at angle å, where å=020, and the rest branch channels of DC have common sections of wide walls with their MW after they are turned through 90- in H plane and oriented to them at angle of 90-å. At that, MW of the main and additional DC after the turn through 90- are parallel to each other. ^ EFFECT: optimisation of emission characteristics. ^ 2 dwg |
