UNIPOLE ANTENNA Russian patent published in 1999 - IPC

FIELD: radio engineering; television, broadcasting, and communications in very-high and ultrahigh frequency bands. SUBSTANCE: unipole antenna has linear monopole array, where monopoles are mounted in parallel one after other, and power line. One of halves of each monopole having quarter-wave length of one frequency band is connected to one of power line conductors at quarter-wave length interval of same band; other halves of monopoles having quarter-wave length of other frequency band are connected to other conductor of power line also at quarter-wave length of other band. As an alternative, high-frequency power is supplied only to second monopole. With power line connected in series with halves of monopoles its sections may be varied as well as linear dimensions of monopole halves proper. Power line may be also connected through resistors. EFFECT: improved efficiency and enlarged operating frequency range. 3 dwg
