RFID Reader for 13.56 MHz Band
Obšitník, Michal ; Zamazal, Michal (oponent) ; Povalač, Aleš (vedoucí práce)
The aim of this thesis is to design an RFID reader for the 13.56 MHz band and to compile a control program. In the first part, the work is aimed at getting acquainted with the principle of operation of RFID and NFC technologies, together with the related international standard, and at getting familiarized with the various transceivers available to operate these technologies. Because the transceiver for the further evaluation is clearly specified in the assignment, their comparison serves a purely informational purpose. In the practical part, the task is to design and revive a prototype RFID reader. The base of the project is a reader board carrying out RFID communication, audiovisual response, and connection to an OLED display. This board is connected to a microcontroller, which controls the whole device. Another part of the project is set of different antennas that can be connected to the reader board and replaced at any time. The manufactured antennas are subject to a testing of how two different tuning methods affect their operation. The maximum reading distance, success of the performed readings and value of the electrical current that is a result of the calibration process are being tested. The output of the thesis is an RFID reader with a control program.
