MONOPULSE FEED Russian patent published in 2010 - IPC H01Q25/02 

FIELD: radio engineering.

SUBSTANCE: each wave guide of channel is arranged as square or round, with exciting wave guides, which are arranged as rectangular and with longitudinal axes perpendicular to longitudinal axis of channel wave guide and is equipped with polariser, which, in transfer mode, transforms horizontally polarised wave excited by the second exciting wave guide, into wave polarised circularly, and in reception mode - circularly polarised wave into vertically polarised wave of the first exciting wave guide. Wave guides of four channels comprises two exciting wave guides each, where the first one excites wave with linear vertical polarisation in channel wave guide, and the second one - wave with orthogonal linear polarisation. Twelve waveguide radiators are arranged in the form of single unit of radiators, and twelve polarisers are arranged in the form of single unit of polarisers.

EFFECT: provision of monopulse feed operation in circularly polarised waves, simplified design, improved manufacturability, reduced labour intensiveness of manufacturing and assembly.
