DOUBLET ANTENNA Russian patent published in 2019 - IPC H01Q1/32 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna-feeder devices, namely to plane antennas of decameter and meter wavelength ranges, and can be used for radio communication of movable, such as cars, and stationary objects. Doublet antenna consists of active part – left and right side sections, central section, symmetrical radio frequency feeder and passive part of U-shape, consisting of long loop, left and right side sections made of plate metal wires, or flat metal grids .Central cores of the feeder cables are electrically connected to side sections of the active part of the antenna. All sections of active part and long flat loop of passive part of antenna are arranged in parallel planes, and side sections of passive part are arranged in planes to them orthogonal, and to the antenna active part central section a rectangular partition is connected, which is equal in geometrical dimensions to side sections of the passive part of the antenna, at that the width of the passive long loop is equal to or slightly larger than the width of the active part of the antenna.

EFFECT: reduced geometric dimensions, reduced non-uniformity of current distribution, improved matching with feeder, increased antenna and traveling wave amplification ratios.
