An RFID (radio frequency identification) electronic tag comprises a substrate, a tag antenna arranged on the substrate and an RFID chip arranged on the antenna; referring to fig. 1 and 2, the tag antenna (2) has a coil structure (21) thereon, and the coil structure (21) is configured to have a pair of spaced apart antenna contacts (22) thereon, with the RFID chip being conductively connected to both antenna contacts. In the production process of the RFID electronic tag, the tag antenna can be formed in the modes of etching, printing and the like. The printing method is to directly print the conductive ink to form the structure of the tag antenna and then stick the chip, so that although the efficiency is high, the conductive ink is very expensive, and the production cost is too high; the etching method needs the procedures of curing, circuit printing, UV curing, etching, ink removal and cleaning and the like on the aluminum foil, is relatively complex, has low production efficiency, and causes serious environmental pollution due to etching; referring to fig. 3, the etching method is to directly adhere the RFID chip to the two antenna contacts after the tag antenna is etched.

The American El Dannison company (NYSE: AVY) develops a die cutting method, which has higher production efficiency and no pollution to the environment, but the die cutting method also has some defects, the die cutting method is to directly die cut the aluminum foil compounded on the substrate and then carry out waste drawing, which is an industry term and means to draw out waste materials; draw useless waste material that needs on the aluminium foil even as an organic whole, just can peel off the waste material is whole, in order to peel off the waste material in the coil structure on the antenna, the distance between two antenna contact should be greater than 2mm, just can avoid drawing the waste material disconnection between useless time two antenna contact. But because the RFID chip is a microchip, the size is very small, the length and the width of the chip which are commonly used are both 0.6mm-0.8mm, and the thickness is 120 μm-150 μm; therefore, the RFID chip cannot be connected with the two antenna contacts for conduction; referring to fig. 4 and 5, the allidanesen company in usa additionally manufactures a pasting member (6), two transfer conductive members (7) are arranged on the pasting member (6), the two transfer conductive members (7) are aluminum foils, the distance between the two transfer conductive members (7) is less than the length of the RFID chip (3), and the RFID chip (3) is connected to the two transfer conductive members (7); the adhesive member (6) is then applied to the tag antenna to connect the intermediate conductive member to the antenna contact. However, the method is still complex and the production efficiency is not high enough; and the thickness of the RFID electronic tag is increased by the adhesive member and the middle conductive member to a certain extent.
