Radio frequency identification (RFID) in the form of tags or transponders is a means of auto-ID that can be used for tracking and monitoring objects, both living and non-living. One of the first applications of RFID was in the 1940s within the US Defense Force (Hodges & McFarlane, 2004, p. 59).

2006 IEEE Antennas and Propagation Society International Symposium, 2006
This paper presents the design of an asymmetric RFID antenna with length smaller than /spl lambda//4 and at the same time achieves the special requirement of the input impedance and also balanced input feed for the tag chip circuit. The antenna has been fabricated and tested by a network analyzer. The antenna design and its performance are presented in

This study has investigated a practically important problem of unknown tag detection that aims to detect the existence of unknown tags in a time-and energy-efficient way. We have proposed a new SBF which is a general case of the standard BF. Based on the new filtering technique, we have further proposed the SBF-UDP. Sufficient theoretically analysis is

Complementary RFID tag antennas
2023This thesis is mainly concerned with the investigation of a systematic approach to selecting tag antennas whose electromagnetic properties are compatible with the platforms on which they are supported and the immediate environment in which they are to be operated. The work is divided into three parts.

The key technical contribution of this chapter is in proposing a protocol to detect and identify missing tag events in the presence of unexpected tags. This chapter represents the first effort on addressing this important and practical problem. The key technical depth of this chapter is in the mathematical development of the theory that RUND and RUNI ...
