HYBRID ANTENNA ARRAY POWER SUPPLY SYSTEM Russian patent published in 2020 - IPC H01Q13/18 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna engineering, particularly to planar antenna arrays (AA) with high efficiency and low level of side lobes. In hybrid antenna array supply system, including radiating part made in form of two-dimensional slot structure located on dielectric substrate, in the form of a grid of collinear antennae excited in series-parallel manner by a microstrip line, said microstrip line includes power points with given amplitudes spaced along the microstrip line by distances which are multiples of the electric wavelength, wherein each power point is connected through a microstrip-coaxial-waveguide transition to the waveguide non-equilibrium in-phase divider, the stages of which are connected in series, wherein the topology of the slot-type collinear antenna forms serially arranged radiating slots excited by the slit line.

EFFECT: technical result is high efficiency, control of amplitude distribution with accuracy of not less than ±0,5 dB and improved range properties of multi-element AA for wideband small-size radio systems.
