ANTENNA ARRAY Russian patent published in 2013 - IPC H01Q9/34 

FIELD: radio engineering, communication.

SUBSTANCE: antenna array has a reflector and multiple radiators, each having a dipole in form of two flat metal elements having identical rectangular arms, an outer conductor and an inner conductor for connecting the dipole to an external signal transmission line. The radiators are mounted on a rectangular flat metal reflector; the radiators are arranged in two lines, with four radiators in each; the centres of the radiators in the upper line are shifted from the centres of the radiators in the lower line by half the distance between the radiators to the right; the distance between the lines on the vertical is equal to 0.5…0.6λ; the reflector has eight rectangular openings whose centres coincide with the centres of the radiators; the openings are meant for connecting the inner conductor of each radiator to an external feeder line for signal transmission; the bottom left lateral edge of the reflector has a rectangular protrusion in the lower half of the reflector and the top right lateral edge of the reflector has a rectangular protrusion in the top half of the reflector with a width of 0.25…0.26 times the distance between the radiators.

EFFECT: wider field of use by providing independent adjustment of amplitude-phase ratios in the circuit of each radiator and high vibration strength design of the structure.
