On the Use of Reverberation Chambers to Simulate a Rician Radio Environment for the Testing of Wireless Devices
Christopher L. Holloway,David A. Hill,John M. Ladbury,Perry F. Wilson,Galen H. Koepke,Jason B. Coder +5 more
TL;DR: In this article, the authors discuss how a reverberation chamber can be used to simulate a controllable Rician radio environment for the testing of a wireless device, and they present both a one-and a two-antenna test configuration approach.
ReportDOI
Industrial Wireless Systems: Radio Propagation Measurements
Richard Candell,Catherine A. Remley,Jeanne T. Quimby,David R. Novotny,Alexandra E. Curtin,Peter B. Papazian,Galen H. Koepke,Joseph E. Diener,Mohamed T. Hany +8 more
TL;DR: Radio frequency (RF) propagation measurements were conducted at three facilities representing a crosssection of different classes of industrial environments, contributing to an improved understanding of radio frequency propagation in factories and an additional perspective on deploying wire less communication devices within factories.
Journal ArticleDOI
Radiated emissions and immunity of microstrip transmission lines: theory and reverberation chamber measurements
TL;DR: In this paper, the authors analyzed the radiation from a microstrip transmission line and calculated the total radiated power by numerical integration and found that emissions measurements are more accurate than immunity measurements because the impedance mismatch of the receiving antenna cancels when the ratio of the microstrip and reference radiated powers measurements is taken.
Proceedings ArticleDOI
Directivity of the test device in EMC measurements
TL;DR: In this article, a statistical theory for estimating the directive characteristics of unintentional emitters based on the electrical size of the device and the pattern measurements in an anechoic chamber is presented.
