MULTIELEMENT LINEAR MODULE OF THE HYDROACOUSTIC RECEPTION ANTENNA Russian patent published in 2017 - IPC H04R1/44 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a sonar antennas of noise control mode (NC) and may be used in discrete linear or two-dimensional curved plane and antenna arrays, including phased. It proposes a multi-element linear module sonar receiving antenna comprising round plate converters electrically combined and placed into the channels in the internal volume of the polymeric tube having a rectangular cross-section along the axis symmetrically with respect to it, so that their large flat surfaces are parallel to the sides of the polymeric hose. The polymer tube filled with compound and sealed with end caps; round plate converters on the symmetry line of the cross section of the cylindrical casing fastened with a glass-cloth substrate by means of circumferential I- rubber junctions glued into the holes in the glass-cloth substrate bonded with two end caps, wherein at polymer hose width symmetrically to its axis two circular plate converter accommodated. Every four adjacent transducer plate, two of which are adjacent along the length of the hose, and two - across its width are electrically combined into one channel so that the channel dimensions along the length and width approximately equal to the hose.

EFFECT: improved directional characteristics of linear multi-element receiver module, it increases noise immunity, provide a wide viewing angle without distortion of the space CN in the extended frequency range.
