METHOD FOR CONSTRUCTING ANTENNA ARRAY Russian patent published in 2023 - IPC H01Q21/26 H01Q21/30 H01Q1/38 

FIELD: antenna technology.

SUBSTANCE: invention is related in particular to transceiver APAA. It is proposed to place the emitters in form of printed vibrators with arms made of metal strips on a dielectric substrate above a conductive screen, while the arms of the printed vibrators are powered by a strip line. The emitters are made as single or crossed printed vibrators, the shape of each arm is formed from an isosceles triangle by applying a fractal Koch curve to its hips, and the base of the triangle is left unchanged. The plane of the dielectric substrate is placed parallel to the conductive screen. The dielectric around the printed vibrators is removed, and through holes are made in their arms, the printed vibrators are excited through a matching device on a printed circuit board installed vertically and connected by the upper face to the dielectric substrate with the printed vibrator, and by the lower face to the conductive screen. When using crossed printed vibrators, for powering each pair of printed vibrators, two matching devices are used, which are installed at right angles to each other, and they are fed by a separate feeder, the edges of the printed vibrators are fixed on dielectric racks, the lower end of which is attached to a conductive screen.

EFFECT: reduction of mass of antenna array.
