FIELD: radio engineering.
SUBSTANCE: invention relates to the field of radio engineering, and more specifically to radio frequency identification systems. Radio frequency identification (RFID) tag with an arbitrary reading angle, including a single-port chip and a two-port antenna connected to it, the antenna being two orthogonally crossed strip radiators located on a dielectric substrate. The tag path between the antenna and the chip port includes matching circuits, a phase shifter and an addition device, while the matching circuits are connected to the antenna, the phase shifter is connected to the matching circuits, the addition device is connected to the phase shifter and the chip in such a way that a turnstile antenna is formed.
EFFECT: forming at least one turnstile antenna capable of receiving and emitting electromagnetic waves of polarization close to circular.
