Performing OTA Measurements in an EMC Range – A Real or False Good Idea?

Getting the money and space for implementing more anechoic chambers serving various test purposes can be a difficult path. The question “Dear Test & Measurement Solution Supplier, I have a large full-vehicle EMC chamber. Could you modify it, so it can do both EMC and OTA measurements?” is increasingly asked these days.

Even though the evaluation of unintended electromagnetic radiation phenomena and intended radiation performance have a lot in common, they also differ in many respects. This talk discusses the trade-off that has to be made when choosing to combine EMC and OTA in one test environment and discusses the scope of specific combinations that work better than others.


Dr. Derat received the engineering degree from SUPELEC in 2002 and a Ph.D. degree in physics from University of Paris XI with honors in 2006. From 2002 to 2008, he worked at SAGEM Mobiles as an antenna design and electromagnetics research engineer. In 2009, he founded ART-Fi, which created the first vector-array Specific Absorption Rate measurement system. Dr. Derat operated as the CEO and President of ART-Fi, before joining Rohde & Schwarz in Munich in 2017. He is now working as Senior Director for Systems Developments and Project Implementations, covering Electromagnetic Compatibility, Over-The-Air, and antenna test applications. Dr. Derat is a Senior Member of the Antenna Measurement Techniques Association (AMTA) and the author of more than eighty scientific conference and journal papers, as well as an inventor on more than forty patents, with the main focus in antenna systems near- and far-field characterization techniques.
