Abstract

The invention provides a RFID antenna and label and an electronic anti-fake bottle cover. In the prior art, an antenna labeled by RFID and a chip are separated from each other, which causes a lot of problems of high space occupation, complex structure, higher manufacturing cost, easy damage in the processes of packaging and transportation, etc. The RFID antenna of the invention is made of a multi-bend folding conducting line and is easily miniaturized, which is convenient to realize the RFID label integrating the antenna and the chip of the invention on the same dielectric medium baseplate, thereby simplifying the structure of the RFID label and reducing the manufacturing cost thereof; and the RFID label which integrates the antenna and the chip is arranged in the electronic anti-fake bottle cover of the invention, and is sealed in the bottle cover, thereby contributing to the reduction of probability of accidental damage of the RFID label and efficiently enhancing the anti-fake property.

Description

technical field [0001] The invention relates to the field of radio frequency identification, in particular to an RFID antenna, a label and an electronic anti-counterfeiting bottle cap. Background technique [0002] Radio Frequency Identification (RFID) technology has been widely used in many fields such as logistics industry and retail industry, which effectively improves management efficiency and greatly saves labor costs. The radio frequency identification system is composed of RFID tags and RFID readers. The working process is that the RFID reader generates electromagnetic waves of a specific frequency and sends them out through spatial coupling (also known as sending question signals). When the RFID reader enters When the reading distance of the RFID tag is reached, the RFID tag will receive the questioning signal and return the electromagnetic wave sent by the RFID reader to the RFID reader after backscatter coupling (that is, a response signal). [0003] RFID technolo...
