Identifying RF Identification Cards from Measurements of Resonance and Carrier Harmonics

May 27, 2010
Author(s)
Henry Romero, Kate Remley, Dylan Williams, Chih-Ming Wang, Timothy X. Brown
We show that careful measurements of the unloaded resonant frequency and quality factor of radio frequency identification proximity cards allow identification of different card models and, for the set of cards we studied, identification with minimal error

The Impact of Long-term Memory Effects on Diode Power Probes

May 15, 2010
Author(s)
Catherine A. Remley, Hugo Gomes, Alejandro Testera, Nuno B. Carvalho, Monica Barciela
This paper presents an analysis of long term memory effects on power measurements using diode power probes. It will be shown that a power probe calibrated with a single-tone sinusoidal excitation can provide erroneous values when used with modulated

Parametric Study on the use of Reverberation Chambers for Repeatable/Controllable Wireless Testing: Application to BER Measurements

April 12, 2010
Author(s)
Christopher L. Holloway, E Genender, Catherine A. Remley, John M. Ladbury, Galen H. Koepke
We illustrate use of the reverberation chamber to simulate different wireless propagation environments including effects such as narrowband or frequency-selective fading and Doppler spread. These effects have a strong impact on the quality of the wireless

Radio Wave Propagation Into Large Building Structures, Part 2: Characterization of Multipath

April 2, 2010
Author(s)
Catherine A. Remley, Galen H. Koepke, Christopher L. Holloway, Chriss A. Grosvenor, Dennis G. Camell, John M. Ladbury, Robert T. Johnk, William F. Young
We report on measurements that characterize multipath conditions that affect broadband wireless communications in building penetration scenarios. Measurements carried out in various large structures quantify both radio-signal attenuation and frequency

From the Editor's Desk: Where to Go

April 1, 2010
Author(s)
Catherine A. Remley
This is an Editorial for the April, 2010 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the Microwave Theory and Techniques Society (MTT-S).

Measurement Bandwidth Extension Using Multisine Signals: Propagation of Error

February 6, 2010
Author(s)
Catherine A. Remley, Dominique Schreurs, M. Myslinski, Dylan F. Williams
We describe a post-processing technique that can extend the effective measurement bandwidth of narrowband vector receivers by phase aligning overlapping measurements. The method requires only knowledge of the desired phases of a periodic, multisine

Comparison of Large-Signal-Network-Analyzer Calibrations

February 5, 2010
Author(s)
Dylan F. Williams, Catherine A. Remley, Joe Gering, Grand Aivazian
We develop a procedure and metrics for comparing large-signal-network-analyzer calibrations. The metrics we develop provide a bound on differences between measurements obtained from large-signal-network-analyzer calibrations, as well as more specific
