Abstract

A label antenna structure suitable for the curved surfaces of liquid containers, comprising a deformed loop (2) surrounding a first slit (5). The deformed loop (2) includes a loop gap (20), a first electrical connection terminal (21), and a second electrical connection terminal (22), with the first electrical connection terminal (21) and the second electrical connection terminal (22) being separated by the loop gap (20). The structure also includes a single-arm radiating plate (3), with one end of the arm of the single-arm radiating plate (3) being connected to the deformed loop (2); a second slit (4), which separates the unconnected portion between the deformed loop (2) and the single-arm radiating plate (3), with one end of the second slit (4) having an open circuit structure (40); and an RFID chip electrically connected between the first electrical connection terminal (21) and the second electrical connection terminal (22).
