 ABSTRACT - Modern society relies increasingly on well-functioning wireless systems - for communication, for sensing, or for energy transfer - and wireless systems rely significantly on well-functioning antennas. Though computational tools improve continuously, the increasing complexity of modern antennas in terms of their functionalities, materials, and structures, as well as always stricter performance requirements, mean that experimental measurements remain of utmost importance for development, validation, and calibration of antennas. But antenna measurement techniques and technologies face numerous near-future challenges due to the wide variety of modern antenna technologies in terms of frequency, bandwidth, radiation pattern, adaptiveness, size and weight, device integration, and dependence on environment, as well as demands for increasing accuracy, decreasing cost and time, and need for characterization in production lines or in-situ operational conditions outside controlled measurement ranges. Furthermore, new wireless technologies call for determination of non-traditional antenna performance metrics which often require substantial post-processing of the raw measurement data. This presentation aims to address state-of-the-art antenna measurement techniques and survey solutions to the many challenges. The presentation takes outset in the recent roadmap paper [O. Breinbjerg and M. Sierre Castañer (Editors), “Antenna Measurement Challenges and Opportunities”, EurAAP Reviews of Electromagnetics, vol. II, 2023] with 19 inspiring contributions by 34 leading experts in antenna measurements.

Biography:

Background: Olav Breinbjerg retired as professor in applied electromagnetics at the Technical University of Denmark (DTU) in 2021 after 30+ years of technical-scientific research, development, and teaching. He was Head of the Electromagnetic Systems Group, the DTU-ESA Spherical Near-Field Antenna Test Facility, and the DTU Electromagnetic Test Centre. He was manager of many projects in cooperation with the European Space Agency (ESA), European and US companies and universities, Danish companies, and he supervised numerous Ph.D and M.Sc. projects. He has been – and is – involved in much international cooperation with a global network of academic and industrial partners.
