Vrednotenje radijskega vmesnika pri tehnologiji radiofrekvenčne identifikacije v pasu ultra visokih frekvenc

VINDIŠAR, DOMINIK (author), Batagelj, Boštjan (mentor)

Zaključna naloga opisuje tehnologijo radiofrekvenčne identifikacije (angl. Radio Frequency Identification – RFID), možnosti uporabe, delovanje in sestavne dele RFID sistema. Vključen je tudi praktični del, v katerem je predstavljen modul v pasu ultra visokih frekvenc (angl. Ultra High Frequency – UHF), merilno mesto in meritve. Z meritvami je cilj ugotoviti, katere RFID značke imajo največjo uspešnost branja pri določenih parametrih. Prav tako so opravljene meritve za določitev optimalne moči oddajanja pri določeni razdalji med anteno in RFID značko. Meritve optimalne oddajne moči so opravljene z značko, ki se je v predhodnih meritvah izkazala za najbolj zanesljivo. Meritve optimalne moči oddajanja so tudi ponovljene z 10 dB slabilnikom.

Abstract

The thesis describes radio frequency identification (RFID) technology, application possibilities, performance, and RFID components. It also includes a practical part in which the ultra-high frequency (UHF) module is described as well as the measuring area and the measurements are presented. With measurements, the goal is to figure out which RFID tags have the highest success rate of reading for certain parameters. The measurements were made to determine the optimum transmit power at a certain distance between the antenna and the RFID tag. The measurements of optimum transmitting power were made with a tag that the testing revealed to be the most reliable one in the previous measurements. In addition, the measurements of optimum transmit power were repeated with a 10 dB attenuator.

• Keywords: RFID, tags, UHF module, success rate of reading (reading performance), optimal transmitting power.power
