METHOD OF CONSTRUCTING ANTENNA ARRAY

FIELD: radio engineering and communications.SUBSTANCE: invention can be used in transmit-receive active phased array antennas. Essence of the invention consists in the following: rectangular insulating substrates, each including one printed dipole are installed equidistantly in units of triangular mesh so that planes of insulating substrates are parallel to each other and perpendicular to a conducting screen, arms of printed dipoles are parallel to a conducting screen at the height less or equal to λ/4, where λ is the average wavelength of operating wavelength range of the antenna array. Distance dbetween adjacent insulating substrates along Y axis is established to ensure the required scanning sector in plane Y, and the distance dbetween centers of printed dipoles along X axis is established to ensure the required scanning sector in plane X. Insulating substrates are connected to each other along Y axis by insulating profiles, where dielectric screws are screwed in through the holes made in the upper and lower corners of each insulating substrate, insulating profiles arranged on end faces of the antenna array have a square cross section, and insulating sections connecting inner edges of insulating substrates have ledges where the edges of insulating substrates are connected by means of dielectric screws. Insulating profiles connected to lower edges of insulating substrates are attached to conducting screen by screws or adhesive. Each printed dipoles are powered with the help of a strip line, its connection to an external feeder is carried out by a plug-in connector located at the base of the insulating substrate.EFFECT: weight reduction and increased vibration strength of the antenna array.1 cl, 1 dwg Изобретение относится к области радиотехники и может быть использовано в приемо-передающих АФАР.
