El Segundo, California – January
Ultra-high frequency (UHF) radio-frequency identification
(RFID) technology is being adopted by a variety of applications such as inventory control
tracking, race timing, attendee tracking, access control, and more. A significant challenge
for RF/microwave designers is performance degradation of UHF RFIDs due to RF interference.
Professor Wang-Sang Lee and his team at
Gyeongsang National University in Korea used NI AWR Design Environment,
specifically Visual System Simulator™ (VSS) system design software, to consider the electromagnetic
interference (EMI) effects of an RFID signal and to analyze the impact of RF interference
in a passive UHF RFID system.
"VSS is easy to use and provides detailed descriptions of each element, which helped
us to quickly and easily analyze the RFID system," said Professor Lee. "The many useful
VSS examples related to recent RF system simulations available through the knowledgebase
were very helpful, as was the responsive technical support."
