Abstract：Antenna is designed based on known specifications to meet the requirements of the systems. Usually the design starts with known basic designs and their variations which nearly achieve the specifications after necessary modification or optimization. This design procedure usually works but suffers from the fact that achievable performance is limited because of limited degrees of freedom (DoF) in design. The limitation is usually caused by not only physical limits such as volume constraints and/or feeding structure design but also limited design space such as selection of workable structures or parameters in design. To meet increasing demands for fast-designed and high-performance antennas, the bottleneck of existing antenna design must be broken. Besides the introduction of new physical concepts such as metamaterials, powerful algorithms have been used to increase DoF of antenna design definitely to generate new opportunities to expand antenna design space for potential to enhance antenna performance. This talk will brief the ways to innovate antenna design. Then the deep learning enabled synthesis method is introduced, as example, for performance enhancement of metacells and metalens antennas. After that a characteristic mode-guided trust-region-based optimization method is introduced for automatically designing mmW dual-band metantenna by mode manipulation.
BIO：Zhi Ning Chen received his two PhD degrees in 1993 from Institute of Communications Engineering, China and in 2003 from University of Tsukuba, Japan, respectively. Dr. Chen has worked in academic, research organizations, and industry since 1988. During 1997-1999, he conducted his research at the University of Tsukuba, Japan with the Japan Society for the Promotion of Science (JSPS) Fellowship Award. In 2001 and 2004, he visited the University of Tsukuba twice under the JSPS Fellowship Program as Senior Fellows. He is currently a Provost Chair Professor and the Director of the Advanced Research and Technology Innovation Center at the National University of Singapore (NUS). He also worked in City University of Hong Kong, Institute for Infocomm Research, Singapore, and IBM Watson Research Center, USA before he joing NUS. Dr. Chen is the founding General Chair of several international workshops and symposiums, including the International Workshop on Antenna Technology (iWAT in 2005), International Symposium on InfoComm & Mechatronics Technology in Bio-Medical & Healthcare Application (IS 3Tin3A in 2010), International Microwave Forum (IMWF in 2010), Asia-Pacific Conference on Antennas and Propagation (APCAP in 2012), and Marina Forum (Mar-For in 2021). He has also been involved in many international events as a general chair, chair, and member of technical program committees and international advisory committees. He has been invited to deliver over 110 keynote, plenary, and invited speeches at international academic and industry events. Dr. Chen has published over 700 academic papers and seven books, as well as held over 36 granted/filed patents and completed over 42 technology licensing deals with industry. He is a pioneer in developing small and ultra-wideband antennas, wearable/implanted medical antennas, package antennas, near-field antennas/coils, three-dimensional integrated LTCC arrays, microwave metamaterial-metasurface antennas. Currently, Dr. Chen is focusing on the translational research of metasurfaces into antenna engineering as well as the development of algorithms, particularly machine-learning-enabled synthesis methods for metantennas. Dr. Chen is the recipient of the IEEE John Kraus Antenna Award (2021) and many other academic and engineering awards. He was elevated to the Fellow of the Academy of Engineering, Singapore in 2019, Fellow of the Asia-Pacific Artificial Intelligence Association (AAIA), and is serving as Vice President of AAIA. He was also elevated to Fellow of the IEEE for his contribution to small and broadband antennas for wireless applications in 2007. He is serving as a Member of the AdCom of the IEEE Antennas and Propagation Society (since 2023). He served on the IEEE Council on RFID as a Vice President and a Distinguished Lecturer (2015-2021), as well as on the IEEE Transactions on Antennas and Propagation as an Associate Editor (2012-2018, 2023-), and the IEEE Antennas and Propagation Society as a Distinguished Lecturer (2009-2012).
