COMPACT WIDE-BAND DIPOLE Russian patent published in 1999 - IPC

FIELD: radio engineering, in particular, antenna-feeder devices. SUBSTANCE: device is designed as symmetrical electric dipole which emitting arms are connected to coaxial line through symmetrical and interfacing circuit. Supply line of electric dipole is designed as coaxial cable which inner conductor is connected to cable piece with two inner conductors, which are connected to one another at first end of cable, but at its second end they are connected in series to one of two inner conductors of power supply line, which are connected to different arms of dipole. External conductor is not connected to arms of dipole. EFFECT: design of compact wide-band radio and TV antennas with L/λ_max ≪ 0,5 and with frequency engagement factor in band 10:1 for standing-wave ratio 2.5. 2 dwg
