Abstract

The invention discloses an RFID tag provided with an arc-shaped opening, comprising a waterproof base sheet, an RFID chip and an RFID antenna connected to the RFID chip signal; the RFID chip and the RFID antenna are packaged In the encapsulation body; the reading distance is long, and the reading distance can reach 11-13m after testing. The reading distance of ordinary RFID tag antennas is less than 10m. Various antennas have good performance, small standing wave ratio, low return loss, high gain and omnidirectionality; they have high performance when used in ultra-high frequency (860-960MHz), especially around 925MHz.

Description

technical field [0001] The invention relates to an RFID tag provided with an arc-shaped opening. Background technique [0002] Radio frequency identification technology (Radio Frequency Identification, abbreviated as RFID) is a technology that uses radio frequency signals to achieve non-contact information transmission through spatial coupling (alternating magnetic field or electromagnetic field) and achieves identification purposes through the transmitted information. Compared with traditional identification technologies (two-dimensional codes, barcodes, etc.), RFID technology has the characteristics of unique marking, large information capacity, fast and convenient reading, multi-label reading, and data encryption. After years of development, it has been widely used in item tracking, aviation luggage sorting, factory assembly lines, car anti-theft, electronic tickets, animal management, commodity anti-counterfeiting and other fields. RFID generally consists of two parts, ...
