COMBINED ADAPTIVE ANTENNA ARRAY Russian patent published in 2021 - IPC H01Q3/26 H01Q21/00 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering and is intended to ensure electromagnetic compatibility of navigation user equipment of the global navigation satellite system (NUE of the GNSS) and tools for creating deliberate radio interference operating at coinciding frequencies. The technical result is achieved by the fact that in the antenna array comprised of N antenna elements forming the antenna array, a pattern-forming circuit comprised of N complex signal weighing units, an adaptive apparatus and an adder with connections with each other, unlike the prototype, K antenna elements are introduced into the antenna array, wherein N antenna elements are arranged in a circle from the centre and have a direction pattern with a minimum in the vertical plane and a maximum in the horizontal plane, K antenna elements are located in the central part and have a direction pattern close to uniform in the upper hemisphere, pattern-forming circuits up to the number of K, K adders and the final pattern-forming circuit with connections with each other.

EFFECT: increased signal-to-interference ratio at the output of the adaptive antenna array.
