“…Presently much effort is dedicated to the development of RFID antennas by implementing various technologies [4][5][6]; however, the development area appears deserted while encountering the issues interconnected to the field of economic and eco-friendly tags comprising of paper substrate. It often overlooked while mentioning the paper printed RFID tags that use of paper defines the entirely new era of electrical performance, which encounters from, new set of issues [7,8]. The polymer-covered paper substrates have been used to demonstrate electrochemical displays.…”

Abstract-Fully integrated printed RFID antennas show potential solution for item level labeling applications. In order to accommodate the antenna during the package printing process, it is vastly preferred that antenna structures are printed on paper substrates. However, the electromagnetic properties and thickness of paper substrates are susceptible to change due to various environmental effects. Thus, adequately consistent in performance and material insensitive printed Quadrate Bowtie RFID antennas are proposed. This paper presents an in-depth efficient optimization for high performance tag antenna designs for operability in frequencies 866-868 MHz & 902-928 MHz. It is demonstrated that the proposed antennas can tolerate a considerable variation in the permittivity on thin paper substrates, and present benchmarking results when n across metal and water containing objects.

“…Besides, we have also investigated and studied such special situation. It can be seen from the assembly site that if such situation occurs in a month and quality issues are rare, tracing method is proposed in the paper that: quality error corrective measures are designed from the position contacting to the parts first when human factors are eliminated; reduce the occurrence rate of defective parts contacting to the position first down and keep observing [10].…”

Abstract-Tracing quality issues of complex automobile gearbox is realized, defective parts and assembly procedures are analyzed and confirmed, analytical method for tracing quality issues is provided and the thinking is illustrated. Furthermore, the tracing model for assembly and quality issues of the gearbox is constructed based on inference principles of the rank sum test; the research results show that the analytical method is effective and feasible in tracing quality issues of the gearbox.

“…The frequency band allocation and transmission power permitted depend on the country or region, and the technology has reduced area coverage, an insufficient range resolution for accurate localization and a scarce multiple-access capability. In addition, UHF RFID technology is also influenced by multipath propagation [4], interference between readers [5] and frequency detuning when tags are attached to materials [6].…”

Abstract-Chipless ultra-wideband (UWB) has been proposed as a low-cost alternative for radiofrequency identification (RFID). In this paper, a comprehensible theoretical introduction to time-domain operation of a UWB RFID tag is described, and a circuit model is proposed. For commercial applications low-cost RFID readers are demanded. To this end, this paper addresses the measurement of time-coded UWB chipless tags for RFID in time domain. Two different setups to detect time-coded tags are presented, one based on commercial UWB impulse radar (IR) and the other based on a vector network analyzer (VNA). The experimental results show the feasibility of using an IR-UWB radar as a UWB RFID reader, achieving very good read ranges.
