One key element of a chipless RFID system is the tag. Since it is chipless, it acts both as the scatterer and encoder. As the scatterer, it needs to reradiate the incident field as much as possible in order to maximize signal-to-noise ratio (SNR) in the reader. As the encoder, it needs to encode a high density of data on the backscattered signal. There

Tag localization in a two-dimensional RFID tag matrix
Future Generation Computer Systems, 2017Localization schemes based on RFID technology are mostly estimating the location of tags either in a two dimensional or in a three dimensional space. In some applications, however, only the relative positions of the tags are needed instead of the exact locations.

Radio frequency identification (RFID) is an automatic identification method for retrieving and accessing data using devices called RFID tags, sometimes called transponders. The basic RFID system includes tags, readers, and associated interfaces, as shown in Fig. 12.1. Tags are attached to objects that we want to identify. Readers query the tags using a

Organic RFID tags are increasingly gaining credibility as a possible low-cost barcode replacement for product identification. This will only happen if organic RFID tags can operate in the frequency range defined by well-accepted EPC standards. This chapter evaluates the performance of existing organic RFID demonstrators and confirms that, based on lab ...

RFID Tagging of Pharmaceuticals
2008Pharmaceuticals play a more prominent role in American health care than in any other nation. The North American market today comprises 47% of the global prescription drug market, which now exceeds half a trillion dollars, with Americans spending approximately $251.8 billion annually on pharmaceuticals.
