RF Engineering and Identification
FEKT-GRFIAcad. year: 2019/2020
Radio frequency identification is a technology, which has recently experienced a rapid growth. The course will focus on linking of knowledge of radio systems and communication and on developing relationships for the RFID use case. Students will find themselves confronted with the topics of RF hardware design, digital signal processing and efficient and secure wireless communication. Knowledge gained in the course will help students in seeking for opportunities in the industrial sector.
Learning outcomes of the course unit
Students passing the course will be able to: (1) explain fundamental operating principles of passive, semi-passive and active RFID, (2) describe the operation of a transponder in an electromagnetic field, (3) describe the architecture of Electronic Data Carriers, Transponder with Memory Function and Microprocessors-based RFID, (4) describe the architecture of an analog frontend of reader and tag and the architecture of the control unit, (5) discuss the properties of the RFID technology in individual frequency bands, (6) design algorithms for digital signal processing (signal shaping, filtering, spectral analysis) in the module of an RFID reader modulator and demodulator, (7) apply the radar equation for signal propagation in real-world scenarios.
The subject knowledge on the Master´s degree level is required.
