ANTENNA ARRAY CONSTRUCTION METHOD Russian patent published in 2019 - IPC H01Q21/29 

FIELD: radio equipment.

SUBSTANCE: invention relates to radio engineering and can be used in transceiving active phased antenna arrays (APAA). According to the method, the antenna array is divided into sub-arrays, each of which contains an even number of vibrators and a conducting sublattice screen, wherein in each sub-grid there installed are rectangular dielectric substrates, each of which comprises a line of printed dipoles, so that the planes of the dielectric substrates are parallel to each other and perpendicular to the sublattice conducting screen, the arms of the printed vibrators are placed parallel to the conducting sublattice screen at a height less than or equal to λ/4, where λ is the average wavelength of the operating wavelength range of the antenna array, in each dielectric substrate in its upper and lower part between the printed vibrators, rectangular slots are made. Dielectric substrates of the subarrays are connected to each other by dense installation of square-section dielectric profiles in these slots, in which transverse grooves are made in places of their installation into slots, each printed vibrator is fed with the help of a stripline line, which is connected to external feeder by means of cutting connectors located at the base of dielectric substrates, wherein distance d_y between adjacent dielectric substrates along the Y axis is set from the condition of providing the required scanning sector in the Y plane, and distance d_x between centres of printed dipoles along axis X – from condition of providing required scanning sector in plane X.

EFFECT: weight reduction and increased vibration strength of the antenna array.
