Abstract

The invention relates to a novel UHF_RFID tag and a manufacturing method. The printed board of the UHF_RFID tag is connected to a metal shell through a metal pin. The internal portion of the UHF_RFIDtag is encapsulated by a high polymer material. In the invention, through the high temperature encapsulation of the high polymer material, a printed board antenna, a radio frequency tag chip and otherstructures are fixed in the metal shell. The excellent mechanical performance and heat resistance performance of the high polymer material ensure that a radio frequency tag can bear a poor engineering environment under a drilling platform. When the radio frequency tag is normally read and written, the dielectric constant of the high polymer material can ensure that a tag antenna has good overallperformance.

Description

technical field [0001] The invention relates to the technical field of UHF_RFID tags, in particular to a UHF_RFID tag and a preparation method thereof. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology. Compared with traditional identification technology, RFID technology has the advantages of waterproof, antimagnetic, high temperature resistance, long service life, large reading distance, tag data can be encrypted, large storage data capacity, and convenient storage of information. [0003] RFID tags are mainly composed of antenna, radio frequency front end, digital baseband and EEPROM. The antenna is used to receive and transmit signals; the RF front-end mainly includes clock generation circuit, envelope detection circuit, modulation and demodulation circuit and power management circuit; EEPROM realizes data storage; digital baseband module mainly realizes established communication protocols, such as da...
