DOUBLET ANTENNA Russian patent published in 2015 - IPC H01Q11/10 H01Q9/26 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to antenna engineering, particularly antenna feeder devices in the decametre and metre wavelength ranges, and can be used in radio communication systems of fixed nodes and facilities in negative environment conditions. To this end, the device comprises an active part having a central section, left and right sections arranged symmetrically about the centre axis of the antenna, and a flat-topped passive part, made from laminar metal conductors and a symmetrical radio-frequency supply feeder, wherein the central section is situated equidistant from both lateral sections.

EFFECT: increasing gain through uniform current distribution and increasing the travelling-wave ratio by improving antenna matching with the feeder.
