Embedded RFID Reader Based 2.4 GHz Microwave

摘要

RFID is a new technique for automatic identification; Reader is key part in RFID system, The paper realizes a new Reader based on FPGA by using 2.4GHz microwave communication frequency because 2.4GHz tags are widely used at present, the Reader has the advantages of flexible structure, small size, easily upgrade, different external interface, etc. Main researching content include: total structure of Reader, interface designing between Radio Frequency module and FPGA, method for reading tag data in FPGA, display of tag data on LCD, reading and writing of tag data on FLASH. The paper describes the realization process. Experimental result is given in the end.
