Reference Modulation for Calibrated Measurements of Tag Backscatter

April 12, 2011
Author(s)
Daniel G. Kuester, David R. Novotny, Jeffrey R. Guerrieri, Randy Direen, Zoya Popovic
This paper presents an active antenna designed to modulate the scattering of an interrogating wave in the 860-960 MHz UHF RFID band. The device can be characterized with straightforward S- parameter measurements, and can then be used for characterization

Link Relationship Measurements in Load-Modulated UHF RFID

October 10, 2010
Author(s)
Daniel G. Kuester, David R. Novotny, Jeffrey R. Guerrieri
This paper investigates the relative roles of the forward and reverse links in determining the operational range of passive UHF RFID systems. The relative importance the links are discussed first in the free field as a first-order model. We then present

Electromagnetic Emissions and Performance for Proximity RFID

March 23, 2009
Author(s)
Jeffrey R. Guerrieri, David R. Novotny, Michael H. Francis, Catherine A. Remley
We examined the electromagnetic emissions, and performance of commercial High-Frequency (HF) proximity Radio Frequency Identification (RFID) systems including their susceptibility to jamming and eavesdropping. These proximity RFID systems are used in an

HF Proximity RFID Electromagnetic Emissions and Performance

November 16, 2008
Author(s)
Jeffrey R. Guerrieri, David R. Novotny, Catherine A. Remley, Michael H. Francis
We examined the emissions, and performance of commercial High-Frequency Radio Frequency Identification (HF RFID) systems to interrupt and eavesdropping. These proximity RFID systems are used in an increasing number of financial, identification, and access

HF RFID Electromagnetic Emissions and Performance

We examined the emissions, and susceptibility of commercial High-Frequency Radio Frequency Identification (HF proximity RFID) systems to interrupt and eavesdropping. RFID systems are being used in an increasing number of financial, identification, and

RFID Devices and Systems in Homeland Security Applications

July 1, 2007
Author(s)
Kate Remley, Jeffrey R. Guerrieri, Dylan Williams, David R. Novotny, Anthony B. Kos, Nelson Bryner, Nader Moayeri, Michael Souryal, Kang Lee, Steven Fick
This article reports on activities being carried out by the National Institute of Standards and Technology to ensure secure, reliable use of Radio-Frequency Identification (RFID) technology in homeland security and public safety applications. These

RFID-Assisted Indoor Localization and Communication for First Responders

October 1, 2006
Author(s)
Jeffrey R. Guerrieri, Michael H. Francis, Perry F. Wilson, Leonard E. Miller, Nelson Bryner, David Stroup, Luke Klien-Berndt
An indoor localization and communication project is described that proposes to use RFID (radio-frequency identification) tags, placed in the building beforehand, as navigation waypoints for an inertial navigation system carried by a first responder. RFID

Three-Antenna Extrapolation Gain Measurement System at Millimeter Wave Frequencies

October 1, 2006
Author(s)
Katherine MacReynolds, Jeffrey R. Guerrieri, Michael H. Francis, Douglas T. Tamura
This paper describes the new tabletop millimeter wave extrapolation range which will provide on-axis gain services up to 110GHz. A discussion of the extrapolation measurement method [1], as presented at the Antenna Measurements Techniques Association (AMTA

RFID-Assisted Indoor Localization and Communication for First Responders

March 7, 2006
Author(s)
Leonard E. Miller, Perry F. Wilson, Nelson P. Bryner, Michael H. Francis, Jeffrey R. Guerrieri, D W. Stroup, Luke Klein-Berndt
An indoor localization and communication project is described that proposes to use RFID tags, placed in the building beforehand, as navigation waypoints for an inertial navigation system carried by a first responder. The findings from the first year of the

Comparison of Gains Determined from the Extrapolation and Pattern Integration Methods

October 30, 2005
Author(s)
Michael H. Francis, Katherine MacReynolds, Jeffrey R. Guerrieri
Scientists at the National Institute of Standards (NIST) have measured the gain of several antennas using two different methods. The first method is the three-antenna extrapolation method developed at NIST in the early 1970s. The second method is the
