“…Radio frequency identification (RFID) is a technology that allows simultaneous identification in a fully automated manner without the need for a line-of-sight via radio waves. Based on these advantages, RFID is widely spreading in various fields, such as smart card, localization, supply chain management, and so on [1][2][3][4]. This paper describes an RFID-based automated steel coil identification system.…”

Abstract-This paper describes the radio frequency identification (RFID)-based steel coil identification system for supply chain management in the steel and iron industry. During crane operation, coil information is automatically updated by reading an RFID tag which is attached to the coil. One of the technical challenges associated with the RFID-based coil identification is the fall of the identification performance due to neighboring metallic objects. In order to cope with this problem, a system was developed in two directions. First, an effective tag attachment method considering the work process and the environmental conditions was proposed. Second, an antenna case was developed to improve the reading performance by minimizing the influence from the attached surface and focusing the RF signal to the target tag. The simulation and experimental results at the POSCO steel company verify that the proposed system can sense the target RFID tag successfully.

“…8, where c = 0.3 and r min = 100 m. Since the RFID system performance are almost the same when c = 0.2 and c = 0.4, we shall use the median value c = 0. 3 placed around the victim reader and r min = 100 m. This percentage value can be referred to as a guiding performance degradation value for deploying RFID systems. Moreover, these values shall increase as the radius of protection area decreases.…”

“…The ultra-high frequency (UHF) band passive radio-frequency identification (RFID) system consisting of readers and tags has been applied to many industrial fields, such as supply chain management, wireless network applications, robotics, etc., as it enables recognition from a distance [1][2][3][4]. In these applications, possibly hundreds of readers will be in operation within a close range to each other.…”

This paper analyzes the performance degradation of ultrahigh frequency (UHF) band radio frequency identification (RFID) protocol due to reader-to-reader interference. First, we establish a modified discrete-time Markov chain model, including a statistical interference model. Then, using this model, we obtain quantitative results of the RFID performance, including tag identification speed (TIS) and query success rate (QSR). By varying the number of interfering readers and the radius of the protection area, the TIS and QSR are simulated and compared to analytical results. Our simulation results show good agreement with the analytical ones in all the simulation cases. When the radius of protection area is 100 m, TIS linearly decreases at the rate of 3.38 tags/sec/reader, while QSR decreases at the rate of 0.57%/reader. The minimal radius of protection area is 400 m when there are little effects of reader-to-reader interference on the performance of the RFID system.

Abstract-A parametric analysis is performed for a wideband Archimedean spiral antenna in recognition of an emerging concept to integrate RFID along with several applications by using a single antenna. The antenna is fabricated using state-of-the-art inkjet printing technology on various commercially available paper substrates to provide the low-cost, flexible RF modules for the next generation of "green" electronics. The effects on electromagnetic characteristics of the planar Archimedean spiral antenna, due to the use of paper are investigated besides other parameters. The proposed antenna is evaluated and optimized for operational range from 0.8-3.0 GHz. It exhibits exceptional coverage throughout numerous RFID ISM bands so do for other wireless applications.
