FIELD: physics.
SUBSTANCE: textile RFID label has an open antenna (4, 4a, 4b) placed on a textile substrate (2), wherein the antenna is connected to an RFID chip (12, 12a, 12b, 24) at the centre region. The antenna (4, 4a, 4b) comprises a loop (6, 6a, 6b) in the center region, the RFID chip (12, 12a, 12b) being connected directly to the shoulders (8, 10) of this loop, wherein the antenna loop (6, 6a, 6b) equipped with the RFID chip serves as a magnetic antenna, and the antenna sections (16, 16a, 16b, 18, 18a, 18b) placed outside the antenna loop serve as an electric antenna.
EFFECT: textile RFID label is suitable for far-region coverage owing to the electric antenna, and for near-region coverage owing to the magnetic antenna.
