EXTENDED-RANGE SUPERHIGH-FREQUENCY DIPOLE ANTENNA Russian patent published in 2006 - IPC H01Q9/16 

FIELD: microwave antenna engineering.

SUBSTANCE: each arm of half-wave dipole is assembled of three conducting semi-rings hinged together at ends and turned to -shaped working position. Dipole arms are reflection symmetric and shorted out at midpoints of upper semi-rings by means of conducting jumper. Each dipole arm can be made of two hinged semi-rings turned to -shaped working position. Arms are shorted out at hinged points of semi-rings. Flat arm width amounts to 0.04 - 0.05 of mean VHF wavelength in operating frequency band of antenna that incorporates provision for excitation dispensing with balancing device.

EFFECT: extended range at adequate matching and gain, improved operating characteristics.
