FOUR-SECTION PHASED ANTENNA ARRAY Russian patent published in 2024 - IPC H01Q9/34 

FIELD: radio engineering.

SUBSTANCE: invention is intended for construction of phased antenna arrays as part of antenna devices of radio communication systems or radar devices. The effect is achieved by the proposed four-section phased antenna array, characterized in that it is manufactured using printing technology, contains four sections of fiberglass, interconnected by a groove connection and is equipped with holes at the outer corners of each section, comprising 32 round flat metal emitter with a vertical and horizontal distance of 0.5…0.6λ of the wavelength of the central frequency of the operating range between them, and the centres of the emitters in the upper line are shifted to the right relative to the centres of the emitters in the lower line by half the distance between the emitters located along the longitudinal axis of the antenna array, perpendicular to the plane of the fiberglass sections, the excitation of which is carried out using pins connected with the back of the antenna to the coaxial feeders using coaxial connectors.

EFFECT: increased vibration resistance and decreased interference of useful and side signals of the antenna array.
