DIELECTRIC CONICAL RADIATOR Russian patent published in 2013 - IPC H01Q13/00 

FIELD: radio engineering, communications.

SUBSTANCE: in a dielectric conical radiator excited at the side of its truncated top with a single-mode dielectric wave guide, and the base of the cone is a radiating aperture, the angle of inclination of a cone generatrix to its height shall not exceed 5°, and the diameter D of the cone base is selected depending on the required width d₀ of the radiated wave bundle on the aperture based on the ratio where λ - length of a radiation wave and ε - relative dielectric permeability of a cone, which shall be within the limits from 2.0 to 2.6. The minimum diameter of the cone base shall meet the ratio and the profile of the guide conical surface from the top to the base is made as linear.

EFFECT: possibility of radiation of an axisymmetric wave bundle of Gaussian type with required width of a bundle, preserving its bundle properties at distances from tens of wave lengths from a radiator aperture.
