Dual Frequency RFID Reader for Active and Passive RFID Tag

摘要

The present invention relates to an integrated RFID reader 109 capable of recognizing active and passive RFID tags with a single RFID reader. The present invention relates to an active RFID antenna 100 for transmitting and receiving active RFID tags and wireless data, and a passive RFID tag. Passive RF antenna 101 for transmitting / receiving wireless data, active RF modulation / demodulation unit 102 for modulating or demodulating the data to be actively transmitted / received to 2.4 GHz, and modulating or demodulating the data to be transmitted / received at 900 MHz to RF at 900 MHz. Only the passive RF modulation and demodulation unit 103, the antenna and the modulation and demodulation unit, and the radio communication unit 104 is electromagnetic shielding to prevent external noise, and only the modulation and demodulation unit to be used to prevent mutual interference by the active and passive RF Switching power supply 105 for supplying power, and the external data and wireless data Data transmission / reception unit 106 in charge of reception and transmission, integrated RF reader 109 and external communication unit 107 for connecting the outside, and active and passive common parts are integrated to prevent mutual interference in one program. The integrated control unit 108 and the integrated RFID reader 109 including all of them.;Tag, RF Reader, Active RF Tag, Passive RF Tag, RFID, RF Antenna, Integrated RF Reader, Switching Power Supply
