BROADBAND ANTENNA Russian patent published in 2010 - IPC H01Q9/34 

FIELD: physics; radio.

SUBSTANCE: invention relates to antenna engineering, and more specifically to vertical broadband transceiving antennae working in the SW range in stationary and field conditions. The broadband SW antenna has a mast, mast extension members, a device for attaching counterbalances, lower and upper commutating rings, where the lower commutating ring is the first antenna feed point, and the second antenna feed point is the electrically connected ends of the counterbalances. On the device for attaching counterbalances, radiators are electrically connected to the lower commutating ring, directed upwards, move way from the mast to bending points, approach each other after the bending points and are electrically connected to the upper commutating ring. The antenna also has a conductor which is electrically connected to the radiators in their bending points, as well as a device for attaching the conductor to the mast, a vertical radiator mounted at the top of the mast with electrical connection to the upper commutating ring. The length of the radiators from the lower commutating ring to the conductor is more than twice larger than the length of the radiators from the conductor to the upper commutating ring.

EFFECT: reduced size, reliability of the structure and reduced loss at low frequencies in the SW band.
