MULTILAYERED DIELECTRIC TOROIDAL ANTENNA Russian patent published in 2020 - IPC H01Q15/08 H01Q15/02 H01Q1/36 

FIELD: antenna equipment.

SUBSTANCE: invention relates to radio engineering, particularly to antenna engineering, and can be used in designing small-size antennae of communication and radar equipment of centimeter and millimeter wave ranges, as well as scanning a beam pattern of a lens antenna. Multilayer dielectric toroidal antenna has a truncated multilayer toroid formed of profiled equidistant elements with a flat lower part, installed concentrically with air gaps relative to each other, and the surface of said elements is formed by rotating non-linear coaxial equidistant surfaces about an axis spaced from the inner part of the profile and which forms a central profiled cavity of the lens; copper substrate with diameter equal to truncated multilayer toroid outer diameter, which acts as zero potential region; active antenna element – asymmetric vibrator of various shape, placed along vertical axis of truncated toroid in inner cavity of toroid.

EFFECT: increased amplification coefficient, reduced number of active elements, simplified matching with receiving-transmitting device and reduced weight of antenna.
