Antennas play a pivotal role in wireless communication and radar systems. While advanced simulation tools facilitate antenna design, the post-fabrication assessment of their performance is equally crucial, yet often overlooked in standard university education. This oversight becomes even more critical as we transition towards 6G technology, where product time-to-market and reputation are paramount.

In this talk, we delve into the significance of radiation efficiency as the ultimate performance metric for antennas and mobile devices. We begin by introducing and comparing existing measurement methods, such as the directivity/gain, integration, Wheeler cap, calorimetric, and reverberation methods. Subsequently, we unveil two innovative approaches, the source-stirred cap/chamber, and TEM cell methods, aimed at delivering cost-effective, swift, and accurate evaluation methods.

Our discussion extends to the underlying theories behind these emerging technologies, equipping you with the latest insights into this dynamic and challenging field. Join us as we explore the frontiers of efficient antenna and mobile device evaluation, shaping the landscape of next-generation wireless communications and radar systems.

个人简介

Yi Huang (Fellow, IEEE) received BSc in Physics (Wuhan, China) in 1984, MSc (Eng) in Microwave Engineering (Nanjing, China) in 1987, and DPhil in Communications from the University of Oxford, UK in 1994.

He has been conducting research in the areas of antennas, wireless communications, applied electromagnetics, radar, and EMC since 1987. More recently, he has focused on new materials for antennas, wireless energy harvesting, and power transfer. His experience includes 3 years spent with NRIET (China) as a Radar Engineer and various periods with the Universities of Birmingham, Oxford, and Essex in the UK as a member of research staff. He worked as a Research Fellow at British Telecom Labs in 1994 and then joined the Department of Electrical Engineering & Electronics, the University of Liverpool, UK as a Faculty in 1995, where he is now a full Professor in Wireless Engineering, the Head of High-Frequency Engineering Group.

Prof Huang has published over 500 refereed papers in leading international journals and conference proceedings and authored four books, including Antennas: from Theory to Practice (John Wiley, 2008 and 2021). He has received many patents, and research grants from research councils, government agencies, charities, the EU, and industry, and is a recipient of over 10 awards (e.g. EuCAP2023 Best Antenna Paper, IET Premium Award for Best Papers 2022, IET Innovation Award 2018, and BAE Systems Chairman’s Award 2017). He has served on a number of national and international technical committees and has been an Editor, Associate Editor, or Guest Editor of seven international journals (including IEEE TAP 2022-date, IEEE AWPL 2016-2022). In addition, he has been a keynote/invited speaker and organiser of many conferences and workshops (e.g. IEEE iWAT2010, LAPC2012, UCMMT2017/2023, and EuCAP2018/2024). He is at present the Editor-in-Chief of Wireless Engineering and Technology, the UK and Ireland Rep to the European Association of Antenna and Propagation (EurAAP, 2016-2020, 2022-date), a Fellow of IET, a Fellow of IEEE, and a Distinguished Lecturer of IEEE AP-S (2022-2025).
