ANTENNA SYSTEM Russian patent published in 1996 - IPC

FIELD: antenna equipment. SUBSTANCE: parallel radiators 20, 21, 22 of antenna system are composed of outer metal cylinders 2,3,4, central conductors 15,16,17 fitted with horizontal conductors 12,13, 14 at upper ends and metal cylinders 9,10,11 positioned between outer metal cylinders and central conductors. Upper ends of cylinders 2,3,4 and cylinders 9,10,11 are interconnected in pairs. Lower ends of cylinders 9,10,11 are grounded and lower ends of cylinders 2,3,4 are insulated from ground and present inputs of radiators. Oscillator 1 is connected to input of first radiator 20. Lower ends of central conductors insulated from ground are outputs of radiators. Tuning and phasing units 18,19 are placed between radiators. Tuning reactive resistors 5,6,7,8 are connected in parallel to inputs of radiators and to output of last radiator 22. EFFECT: enhanced operational efficiency. 1 dwg
