Backscatter Communication using Ultrawide Bandwidth Signals for RFID Applications
نویسندگان
چکیده
Future advanced radiofrequency identification (RFID) systems are expected to provide both identification and high-definition localization of objects with improved reliability and security while maintaining low power consumption and cost. Ultrawide bandwidth (UWB) technology is a promising solution for next generation RFID systems to overcome most of the main limitations of current narrow bandwidth RFID technology, such as reduced area coverage, insufficient ranging resolution for accurate localization, low security, sensitivity to interference and scarce multiple access capability. In this paper, the UWB technology is applied to (semi-)passive RFID based on backscatter modulation and the potential performance is investigated in terms of bit error rate/data rate trade off using measurement data in real environment.

Laissez-Faire: Fully Asymmetric Backscatter Communication – Public Review
Laissez-Faire is a novel design for backscatter communication that enables much higher data rates. The key idea is simple and elegant. The authors note that low-power backscatter systems, e.g., RFIDs, transmit their signal using ON-OFF keying –i.e., they convey bits by transitioning the signal between two levels, up and down. However, since their bit rate is low (tens of kbps), they have a smal...

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
