DISK-CONE BROADBAND ANTENNA Russian patent published in 2023 - IPC H01Q9/28 H01Q9/44 

FIELD: antennae.

SUBSTANCE: antenna includes an input RF connector, a horizontally located conducting disk, a vertical conducting cone located under it, a vertical tube is located above the disk, having an electrical connection with the centre of the conducting disk, both disk and cone are made of tubes. Above the conducting disk there is a small vertical conducting cone made of tubes, the vertical axis of which lies on the same line with the vertical axis of the large vertical conducting cone, and the apex is electrically connected to the centre of the conducting disk. Part of tubes of the conducting disk are equally shortened, while both short and long tubes are evenly located in the plane of the disk, and the lengths of the short and long tubes of the conducting disk are related by the ratio L_sh. =0.635⋅ L_long, where L_sh. is the length of a short tube, L_long is the length of the long tube. The heights of the small and large vertical conducting cones are related by the ratio Н_small =0.322⋅ N_large, where H_small. is the height of a small vertical conducting cone, N_large is the height of the large vertical conducting cone. The height of the vertical tube and the height of a large vertical conducting cone are related by the ratio H_h. = 0.644⋅ N_large, where H_h. is the the height of the vertical tube.

EFFECT: expansion of the operating frequency range of the antenna without using the matching circuit by changing the geometry of the disk-cone antenna.
