Label antenna structure suitable for the curved surfaces of liquid containers

A label antenna structure suitable for the curved surfaces of liquid containers, comprising:

• a deformed loop surrounding a first slit, the deformed loop including a loop gap, a first electrical connection terminal, and a second electrical connection terminal, with the first electrical connection terminal and the second electrical connection terminal spaced apart by the loop gap;
• a single-arm radiating plate, an arm end of which is connected to the deformed loop;
• a second slit, with the portion of the deformed loop and the single-arm radiating plate that is not connected to each other being spaced by the second slit, the second slit having an open circuit structure at one end;
• an RFID chip electrically connected to the first electrical connection terminal and the second electrical connection terminal;
• a third slit, with the third slit spaced between the single-arm radiating plate and the second slit;
• the deformed loop, the first slit, and the third slit form impedance matching, with current flowing through the first slit and the third slit to adjust an inductive reactance of the label antenna structure suitable for the curved surfaces of liquid containers and a capacitive reactance of the RFID chip.
