Disclosed is an RFID radio-frequency antenna applied to a clothing label and a book. The RFID radio-frequency antenna is characterized in that: a resonant cavity wire is encircled to form a rectangular resonant cavity, a notch-shaped chip binding position is formed in the middle of one long side of the resonant cavity, two radio-frequency antenna fins extend from the other long side of the resonant cavity, the radio-frequency antenna fins extend towards the two sides to form S-shaped extension portions, the initial end of each S-shaped extension portion is 1.5 millimeters in width while the end is 2.75 millimeters in width, and each of the left and right S-shaped extension portions is 45 millimeters in length and 24 millimeters in width. The present utility model has a very high read sensitivity, compared with a traditional radio-frequency antenna with the same area, the read distance is longer, and batches of radio-frequency label chip information can be read more easily in one time; a punching model for a punching antenna is convenient to be manufactured, and the radio-frequency antenna can be manufactured by using a punching technology; the present utility model has low manufacturing cost, is pollution-free, and is convenient for large-area popularization. |
