Ultrahigh frequency radio frequency tag with reduced size and maintained performance

Abstract

The invention discloses an ultrahigh frequency radio frequency tag with reduced size and maintained performance. The tag comprises a tag main body, and is characterized in that a protection mechanismis arranged on the outer side of the tag main body; and the protection mechanism comprises an antistatic layer arranged on the upper surface of the tag main body, a protection film arranged on the upper surface of the anti-static layer, an anti-radiation layer arranged on the lower surface of the tag main body, a bonding layer bonded to the lower surface of the anti-radiation layer and a release paper layer attached to the surface of the bonding layer. Through designed PET silica gel protective film, PE antistatic layer and waterproof layer, the tag is prevented from being extruded and scratched by foreign objects, through the anti-radiation layer, and it is prevented that when the tag is attached to equipment, radiation of the equipment influences identification of the tag; through a groove-shaped shielding layer, signals generated by the tag are transmitted to one direction through the shielding layer, and identification reading and writing are facilitated; and an antenna is accommodated at one side of a chip, so that the size is further reduced and the use of the tag is not influenced.

Description

technical field [0001] The invention belongs to the technical field of tags, in particular to an ultra-high frequency wireless radio frequency tag with reduced size and maintained performance. Background technique [0002] The principle of radio frequency identification is to conduct non-contact data communication between the reader and the tag to achieve the purpose of identifying the target. The application of RFID is very extensive. At present, typical applications include animal chips, car chip anti-theft devices, access control, parking lot control, production line automation, and material management. The electronic tag completes the information exchange by accepting the microwave signal transmitted by the radio frequency identification reader, and obtaining energy through the electromagnetic induction coil to supply itself for a short time. Because the power supply system is omitted, the volume of passive RFID products can reach the order of centimeters or even smalle...
