LOW FREQUENCY FILTERING UNIT WITH HIGHLY STABLE DIRECTIVE PATTERN AND ANTENNA ARRAY Russian patent published in 2023 - IPC H01Q1/36 H01Q1/52 

FIELD: radio engineering.

SUBSTANCE: invention relates to antenna technology, in particular, to a low-pass filtering unit with a highly stable radiation pattern. The effect is achieved by proposing a low-pass filtering unit with a highly stable directivity pattern, containing a vibrator arm, a balun base, a balun power line and a balun chamber tube to accommodate the power line of the balun, in which the vibrator arm includes longitudinal and transverse radiating arms, connected vertically to form a single L-shaped rectangular structure, wherein the chamber tube of the balancing device is located at the connection between the transverse radiating arm and the longitudinal radiating arm, while the transverse radiating arm and the longitudinal radiating arm, each separately, are equipped with a barrier structure, while barrier structures on the transverse radiating arm and longitudinal radiating arm are located symmetrically relative to the L-shaped rectangular structure dividing into angles of 45° bisectors as the axis of symmetry.

EFFECT: enhanced filtering properties and smoothed out distortions in the antenna system's radiation pattern.
