Electronic tag

Abstract

The invention provides an electronic tag. The electronic tag comprises a support plate, radio frequency identification (RFID) antennas, an RF integrated chip, a first metal connecting wire and a second metal connecting wire, wherein the support plate comprises a first region and a second region; the RFID antennas are formed on the first region of the support plate and comprise first ends and second ends; the first ends spirally extend outwards to the second ends in a ring shape; the RF integrated chip is glued on the second region of the support plate and comprises a first interface and a second interface; the first metal connecting wire and the second metal connecting wire are arranged above the RF integrated chip and the RFID antennas; the first metal connecting wire electrically connects the first ends of the RFID antennas with the first interface of the RF integrated chip; the second metal connecting wire electrically connects the second ends of the RFID antennas with the second interface of the RF integrated chip. The electronic tag has the advantages that the electronic tag occupies a small area, and the RFID antennas have high repeatability and improved electrical properties.

Description

technical field [0001] The invention relates to radio frequency identification technology, in particular to an electronic label. Background technique [0002] RFID (Radio Frequency Identification: Radio Frequency Identification) is a non-contact automatic identification technology, which automatically identifies the target object and obtains relevant data through radio frequency signals. It does not have the advantages of waterproof, high temperature resistance, long service life, large reading distance, data on the label can be encrypted, storage data capacity is larger, and storage information can be changed freely. Its application will bring revolutionary changes to industries such as retail and logistics. . [0003] The basic RFID system consists of a reader (Reader) and an electronic tag (or transponder, Transponder). Among them, the electronic tag (Tag): consists of a radio frequency identification antenna and a radio frequency integrated chip. Each electronic tag has...

AI Technical Summary

Problems solved by technology

The radio frequency identification antenna is formed by winding the metal wire or wire several times by winding the wire or embedding the wire into the carrier sheet to form the radio frequency identification antenna. The formed radio frequency identification antenna will occupy a large space, and the repetition of the coil of the radio frequency identification antenna Low resistance, which affects the electrical performance of the radio frequency identification antenna
