In this paper, we discuss antennas and propagation aspects in current passive UHF RFID
systems. We consider a" reader-tag-reader" link and concentrate on each part of it: reader …

RFID is an automatic identification technology that enables tracking of people and objects.
Both identity and location are generally key information for indoor services. An obvious and …

In this paper, the reverse-link interrogation range (RIR) of ultrahigh-frequency-band passive
radio-frequency identification (RFID) is analyzed for single-input and single-output (SISO) …

In this paper, the effects of ultrahigh-frequency band passive radio-frequency identification
(RFID) reader-to-reader interference are investigated in terms of the interrogation range. A …

In this paper, RFID reader-to-reader interference is analyzed from the point of view of
interrogation range. To evaluate RFID interference quantitatively, the new figure-of-merit …

Recently, the problem of scheduling readers to read maximum tags such that readers and
tags can be avoided collision within a given multiple interrogation ranges of reader has …

In this paper, a UHF-band 2 times 2 microstrip phased-array antenna is designed and
implemented to extend the coverage of an RFID reader system. The phased-array antenna …

This paper introduces an interrogation enhancer (IE) as an external system that boosts a
reader continuous wave (CW) with its auxiliary CW. The boosted reader CW powers the …

In RFID, readers operating concurrently may interfere mutually up to distances in the order of
hundreds of meters due to the extremely low power of the tag backscattered signal, causing …

The wireless use of radio frequency waves for data acquisition and transfer is known as
Radio Frequency Identification (RFID). RFID-based systems have been applied in various …
