DIPOLE ANTENNA Russian patent published in 2004 - IPC

FIELD: antenna-feeder facilities employed as antenna-feeder facilities, phased arrays and antenna system.

SUBSTANCE: dipole antenna which arms are made in the form of uniaxially positioned elements includes one element which is grounded and is bearer, it has inside coaxial supply line connected to upper arm of antenna at distance L1 from its lower end and at distance L2 from nearest joints of bearing element with outer elements of upper and lower arms of antenna. Bearing element has connections with outer element of lower arm at distance L3 from its upper end and L2 from its lower end. Length of each arm is equal to half-length of wave λ_u on upper frequency of working frequency range, L1=L3 and L2 is equal to Ѕ wave length λ_m on medium frequency of working frequency range.

EFFECT: directive gain of antenna.
