THREE-DIMENSIONAL PHASED ANTENNA ARRAY AND METHOD FOR ITS MANUFACTURE USING ADDITIVE TECHNOLOGIES Russian patent published in 2023 - IPC B64C1/36 H01Q21/29 

FIELD: radio engineering.

SUBSTANCE: invention is related to phased antenna arrays (PAR), and is used in wireless communication systems for receiving and transmitting information in the microwave range. A three-dimensional phased array is proposed, which has an operating frequency range in the microwave region, consisting of three-dimensional conductive radiating elements that form nodes of regular square cells of a periodic structure M×N, manufactured using additive technologies of 3D printing of a plastic frame, and its subsequent selective metallization by an electrochemical method, said cells are located above the reflective element of the dielectric platform, connected by electrical contact to a transmission line made on the second side of the dielectric platform, which is a product made of double-sided metallized fiberglass, one side of which is a conductive metal mirror, the other side is a transmission line, while the dielectric platform provides a given value of the amplitude and phase of the electromagnetic signal at each node of a regular square cell.

EFFECT: increase in the gain and directivity of the antenna array.
