- Abstract
- As ultra high frequency (UHF) radio frequency identification (RFID) technology, a smart recognition technology, has been gradually spreading to various applications, and several sub-1GHz wireless technologies are being standardized and developed. As such technologies operate at a specific frequency band (902-928 MHz industrial, scientific, and medical bands), the impact of RF interference due to performance degradation of UHF RFID technology on the interference signal is emerging as a new obstacle. In this paper, we investigate the interference analysis and experimental results of passive UHF RFID systems in sub-1GHz wireless communications systems. By considering interference signal frequency and power, interference deployment, antenna polarization, RF system-level analysis and experimental verification are conducted to evaluate the impact of performance degradation in the UHF RFID system on the interference signal. ? 2017, Electromagnetics Academy.
