Design and development of a RFID reader with carrier frequency of 125 KHz

Lucian Nicolae Cojocariu


This paper presents the development of a low frequency Radio Frequency Identification transceiver system aimed at providing non-contact solutions for identifying, monitoring, and tracking people, animals, and objects. The communication between Radio Frequency Identification reader and transponder is done wireless. When the transponder is placed in the electromagnetic field emitted by the RFID reader antenna, it is activated and the information stored is transmitted in digital form by modulating the field emitted by the reader antenna. Various antenna configurations were analyzed and the optimal configuration was chosen for the implementation.
