As the price of passive radio frequency identification (RFID) tags continues to decrease, more and more companies are considering item-level tagging. Although the use of RFID is simple, its proper application should be studied to achieve maximum efficiency and utilization in the industry. This paper is intended to demonstrate the test results of various multisurface UHF tags from different manufacturers for their readability under varying conditions such as orientation of tags with respect to reader, distance of tag from the reader, and materials used for embedding tags. These conditions could affect the reliability of RFID systems used for varied applications. In this paper, we implement a Design for Six Sigma Research (DFSS-R) methodology that allows for reliability testing of RFID systems. In this paper, we have showcased our results about the benchmarking of UHF RFID tags and have put forward an important observation about the blind spots observed at different distances and orientations along different surfaces, which is primarily due to the polarity of the antenna chosen.

“…It can be derived from (1), by imposing being the IC sensitivity provided by the manufacturer (5) The presence of the multi-path, caused by the interaction with the environment, is not taken into consideration here because of the expected small reader-tag distances achievable within the allowed emitted power. It was demonstrated in [17] that for low-gain tags, as in case of implanted antennas, the free-space formula is still useful to predict the read region.…”

Abstract-Numerical processing of passive UHF-RFID tags' response may provide physical insight about the hosting object or about the nearby environment. This idea is here extended to implanted antennas with the purpose to sense the evolution of some human physiological and pathological process involving a local change of effective permittivity inside the body. The goal is to understand how master the design of this class of devices taking into account both communication and sensing capabilities. An ad hoc design methodology is here presented and discussed by means of a realistic medical case concerning the modification of an endo-vascular device to achieve a STENTag able to sense the state of the vessel wherein it has been implanted.Index Terms-Biosensor, implantable biomedical device, passive sensing, RFID.

“…Although the free space channel model [18] may not be adequate in real application environments [19] or in the presence of strong tag-totag coupling [20], it is well-suited for tag antenna design verification in controlled environment. Moreover, in applications such as the one considered in this article, with relatively short tag read range, the effect of the multipath propagation is limited [19].…”

Abstract-The development of a compact metal mountable RadioFrequency IDentification (RFID) tag antenna on a ceramic substrate based on Barium Titanate is presented. The performance limitations and design trade-offs of metal mountable RFID tag antennas are reviewed and the favorable features of a high-permittivity antenna substrate for the development of antennas for metal mountable RFID tags are discussed. The simulation-based tag antenna design process is outlined and the measured read range of the developed metal mountable tag on conductive platforms of various sizes is presented.
