An ultra-low-cost RFID tag with 1.67 Gbps data rate by ink-jet printing on paper substrate

A fully metallic ink-jet printed passive chipless RFID tag on paper substrate is presented. The tag consists of an ultra-wide-band antenna, a microstrip transmission line with distributed shunt capacitors as information coding element which is reconfigurable by ink-jet printing process. Tapered microstrip line is employed to overcome the limitations of low conductivity and thin film thickness of ink-jet printed metal tracks. Measurement results show that the tag features a robust readability over 80 cm reading distance and a high data rate of 1.67 Gb/s.

Design and analysis of efficient and compact antenna for paper based UHF RFID tags

Paper substrate is one of the paramount nominees for radio frequency identification (RFID) tags but at the same time it is extremely prone towards environmental changes. In this paper, antennas for UHF RFID tags on paper based substrate are investigated and analyzed for the first time to evaluate the effect of change in dielectric constant on the antenna parameters and performance. On the basis of analysis a concrete meander line antenna is proposed, designed and evaluated which has tremendous immunity towards variation in dielectric constant.

Evaluating Sustainability, Environmental Assessment and Toxic Emissions during Manufacturing Process of RFID Based Systems

The present state of the art research in the direction of embedded systems demonstrate that analysis of life-cycle, sustainability and environmental assessment have not been a core focus for researchers. To maximize a researchers contribution in formulating environmentally friendly products, devising green manufacturing processes and services, there is a strong need to enhance life-cycle awareness and sustainability understandings among embedded systems researchers, so that the next generation of engineers will be able to realize the goal of a sustainable life-cycle. In this work an attempt has been made to investigate and evaluate the life-cycle management and environmental assessment in fabricating processes of the RFID based systems. We have chosen a general life cycle assessment approach which involves the collection and evaluation of quantitative data on the inputs and outputs of materials and energy associated with the RFID based systems. Based on the developed generic models, we have obtained the results in terms of environmental emissions for a production of paper substrate printed RFID antennas. We also make an attempt to raise several sustainability issues and quantify the toxic emissions during the manufacturing process.
