BALLOON ULTRASHORT-WAVE ANTENNA Russian patent published in 2008 - IPC H01Q1/28 

FIELD: antenna engineering; balloon-lifted nondirectional transceiving antennas.

SUBSTANCE: proposed ultrashort-wave balloon antenna has metal container accommodating radio station and conductors running above container surface parallel to its longitudinal axis. Counterpoise in the form of metal disk and conductors radially diverging from its edge is installed in cavity perpendicular to container longitudinal axis. One end of each conductor disposed above container is connected to container base and other, to counterpoise metal disk. Container surface is connected in addition to each of these conductors through shorting jumper. Coaxial feeder is disposed in cavity of one of jumpers and in part of conductor running to metal disk, feeder external sheath being connected to disk center and central conductor, to container top. U-shaped conductors are connected in addition to container body.

EFFECT: extended operating frequency range.
