TRIPLE-DIPOLE ANTENNA Russian patent published in 2008 - IPC H01Q11/02 

FIELD: radio engineering; radio communication and data transfer systems.

SUBSTANCE: proposed antenna is characterized in that it has newly introduced second and third conductors apart from first one, their first ends being interconnected in common point at angle of 120 ± 10° and other ends are loose; length of first conductor is greater than operating quarter-wavelength by 10 - 15%, that of second conductor having inductive load inserted in its center is smaller than operating quarter-wavelength by 10-15%; length of third conductor having inductive load inserted in its center is smaller by 5-10% than operating quarter-wavelength.

EFFECT: enhanced gain, provision for circular directivity pattern, improved matching with feeder, reduced size.
