Design and implementation of 2.4GHz RFID tags

A novel active RFID tags working in 2.4GHz is presented. Then hardware design and software programme are addressed. For the radio front-end,nRF24L01 are used which is single chip wireless transceiver and all work's parameter are set by the means of software in it. In this way, the process of encoding is simple and have better performance on anti-interference . In orded to realize low-power design, various mode of radio front is adopted based on microcontroler. The result shows that under the condition of same distance of identify,this method brings up less tag size and lower power compared with that of traditional design of WM RFID tags.
