CONICAL DOUBLE-THREAD HELICAL ANTENNA Russian patent published in 2024 - IPC H01Q1/36 H01Q11/08 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna equipment and serves to organize combined for reception and transmission of antenna-feeder systems of command-telemetric radio lines. Disclosed is a conical double-threaded helical antenna, characterized by the fact that it consists of a central conductor, single part, which is made according to additive technology and includes two equiangular spiral radiators, made in the form of tapes, round metal disc-base, and external conductor of balancing device, made in form of round coaxial waveguide, narrow ends of spiral radiators are electrically connected to output conductor of balancing device, and wide ends with edge of disc-base, at that, a row of metal cylinders with gradually increasing radius is added to the central conductor, outer conductor is reinforced with symmetrical stiffeners attached to the disk-base.

EFFECT: wider operating frequency band of the antenna with simultaneous increase in the mechanical strength of its structure.
