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 researcher's contribution in formulating environmentally friendly products, devising green manufacturing processes and services, there is a(More)
Future high-performance wireless communication applications such as wireless local area networks (WLANs) around 5 GHz require low power and high quality integrated transceiver solutions. The integration of RF front end especially poses a great challenge to these applications as traditional system on chip (SOC) approach is quite inefficient. A system on(More)
We demonstrate for the first time an RFID tag antenna which itself is humidity sensor and also provides calibration functional-ity. The antenna is comprised of T-matching network and horizontally meandered lines for impedance matching and reliable near-field communication. The novel contour design provides humidity sensing, and calibration functions whilst(More)
In this paper, a novel 9-bit flexible chipless RFID tag design with a size of 10.5 &#x00D7; 15 mm<sup>2</sup> is proposed. The tag is analyzed for Kapton<sup>&#x00AE;</sup>HN and Polyethylene terephthalate (PET) substrates. The tag based on Kapton<sup>&#x00AE;</sup>HN substrate is operating in a frequency band of 8&#x2013;19 GHz, while PET based tag(More)
In this paper, we demonstrate for the first time an RFID tag antenna manufactured by advanced inkjet printing technology on paper substrate using novel hole-matching technique for reducing the consumption of substrate material and conductive ink while attaining green RFID tags. In-depth electromagnetic analysis is performed methodologically for optimizing(More)
The transceivers for future technology (third generation cellular, wireless LAN) need to be portable (compact), battery-powered and wireless. The present single-chip solutions for RF front-ends do not yield complete system integration. A system-on-a-package (SoP) approach can solve these problems. High quality components can be integrated in the package.(More)
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(More)
