BICONICAL ANTENNA Russian patent published in 2014 - IPC H01Q13/04 

FIELD: radio engineering, communication.

SUBSTANCE: antenna comprises two identical dipoles, each in form of a metal cone made of a good conductor. The longitudinal axis of the dipoles coincides with the longitudinal axis of the antenna, wherein the dipoles in the antenna face each other by their vertices, which are connected to a matching-balancing device, which is the input/output of the antenna. Concentric zigzag-shaped grooves are made around the lateral surfaces of the cones of the dipoles to form a corrugated surface. In other versions of the antenna, grooves in the longitudinal axial section have a rectangular, sinusoidal, triangular or trapezoidal shape.

EFFECT: high sensitivity in the high-frequency range.
