Electromagnetic Modelling of UHF RFID Tags*
نویسندگان
چکیده
Paper presents a method for analysis of UHF RFID tags. After a brief overview of RFID system and UHF tags an electromagnetic (EM) simulation of tags in WIPL-D software was conducted. Electrical matching was performed after which tags were excited by a uniform EM wave, induced powers were measured and tag characteristics were compared.

متن کاملAntenna-Based Passive UHF RFID Sensor Tags - Design and Application
RFID, as a low cost technology with a long life time, provides great potential for transmitting sensor data in combination with the ordinary ID number. The sensor can, for example, be integrated either in the chip or in the antenna of an RFID tag. This thesis focuses on the design of antenna-based UHF RFID sensor tags as wireless sensors at the lowest possible cost level compatible with standar...
متن کاملPerformance benchmarks for passive UHF RFID tags
This paper describes the first comprehensive benchmark suite for passive UHF RFID tags. These benchmarks give good indications as to how well RFID products will work in “real world” scenarios. We present benchmarks and give some experimental results, as well as key insights that these benchmarks have revealed about the nature of current UHF RFID tags on the market.
متن کاملRFID and Its Vulnerability to Faults
Radio Frequency Identification (RFID) is a rapidly upcoming technology that has become more and more important also in securityrelated applications. In this article, we discuss the impact of faults on this kind of devices. We have analyzed conventional passive RFID tags from different vendors operating in the High Frequency (HF) and Ultra-High Frequency (UHF) band. First, we consider faults tha...
متن کاملDesign and Fabrication of Miniaturized Fractal Antennas for Passive UHF RFID Tags
Generally, passive RFID tags consist of an integrated circuit (RFID chip) and an antenna. Because the passive tags are batteryless, the power transfer between the RFID's chip and the antenna is an important factor in the design. The increasing of the available power at the tag will increase the read range of the tag which is a key factor in RFID tags. The passive RFID tag antennas cannot be tak...
