OMNIDIRECTIONAL ANTENNA SYSTEM WITH SPECIAL DIRECTION PATTERN Russian patent published in 2017 - IPC H01Q21/29 

FIELD: radio engineering, communication.

SUBSTANCE: system consists of a vertical support with a transverse dimension (0.18-0.25) of the wavelength with two reflectors installed on it and N (where N is an integer number) of identical radiators, the vertical support being made in the form of a hollow metal column, N identical radiators are made in the form of dual conformal radiators, and two reflectors are continuous along the entire length of the hollow metal column, and each of the N double conformal radiators placed along the column at a distance of about half the wavelength consists of two conformal n the radiant emitters placed on opposite sides of a hollow metal column repeating the shape of its cross-section and connected by means of a coupler with a divider into two directions, the lateral faces of the conformal strip radiators having rectangular cutouts and the outputs of the signal divider for N directions placed inside the column, are connected to the inputs of N dividers into two directions connected to each of the two conformal strip radiators.

EFFECT: reducing the unevenness of the directional pattern in the horizontal plane, the lack of tuning while ensuring the minimum value of unevenness and providing the possibility of forming a directional pattern of a special shape in the vertical plane, in particular, the cosecant.
