BROADBAND DIPOLE ANTENNA Russian patent published in 2003 - IPC

FIELD: antenna-feeder devices. SUBSTANCE: broadband dipole antenna has first and second arms of first dipole forming gap as result of vertical-diversity distance; first and second arms of second dipole; first and second conductors; coaxial feeder; balun; equalizer provided with first and second inputs; first conductor interconnects first and second arms of first and second dipoles; second conductor interconnects first and second arms of second dipole; feeder conductor is connected to second arm of first dipole in mentioned gap; central conductor of feeder is connected to first input of equalizer whose second input is connected to first arm of first dipole in mentioned gap. Described in detail is experimental antenna whose standing-wave ratio in 16% frequency band is lower than 1.15. Antenna is reliably protected against antenna feeder effect. It may be used as component of antenna array, for instance to provide for joint operation of several ultrashort-wave frequency-modulation television broadcast stations, as well as professional communication station, and other high-frequency and very-high-frequency systems using single antenna array, including antenna arrays mounted on tower bands ensuring circular directivity pattern in horizontal plane. EFFECT: enlarged operating frequency band. 8 cl, 13 dwg
