PASS-THROUGH GRATING WITH CONTACTLESS STRUCTURE AND SINGLE-BIT CONTROL FOR FORMATION OF MULTIBEAM PATTERN Russian patent published in 2021 - IPC H01Q1/00 

FIELD: antenna equipment.

SUBSTANCE: invention relates to antenna technology, in particular to the design of an antenna array cell and to a pass-through antenna array based on such cells. The technical result is achieved by the fact that the antenna array cell contains a central printed circuit board including a slot structure having symmetry, and at least two switching elements that are located in the said slot structure symmetrically relative to the plane of symmetry of the slot structure, input and output polarization filters, as well as a control line for controlling the switching elements, and one of the polarization filters is made with the ability to pass radiation with a polarization parallel to the plane of symmetry of the said slot structure, while the other of the filters is made with the ability to pass radiation with a polarization perpendicular to the plane of symmetry of the mentioned slot structure, and the input polarizing filter, the central printed circuit board and the output polarizing filter are separated from each other by a gap.

EFFECT: reduction in size and simplification of the structure of the cells of the controlled pass-through antenna array.
