WAVEGUIDE ANALOGUE OF DIPOLE ANTENNA ARRAY Russian patent published in 2016 - IPC H01Q21/00 

FIELD: antennas.

SUBSTANCE: invention relates to antenna engineering. Device comprises a rectangular waveguide section, in the end of which there is a short-circuiting plunger, and on its side walls, in their plane of symmetry, there are quarter-wave pin radiators, herewith on the short-circuiting plunger in its center of symmetry there is a vibrator connected to a coaxial feeder having a symmetrizing slot, and the quarter-wave pin radiators are connected to coaxial feeders via short-circuited loops, herewith the quarter-wave pin radiators are connected to corresponding side walls of the rectangular waveguide with semi-cylindrical conductors formed by the diameter section in the H-plane of the external conductor of the coaxial feeder, and the short-circuited loops are connected at the distance of λ/4 from the point of connection of the quarter-wave pin radiator, where λ is the operating wavelength.

EFFECT: technical result is expansion of the bandwidth with higher accuracy of simulation.
