Abstract: Cutting-edge additive manufacturing technologies will enable three-dimensional (3D) radio frequency and millimetre-wave electronics with exceptional performance for emerging intelligent and immersive technologies, including 5G/6G communications, terahertz sensing, microwave biomedical imaging, wearable and implantable sensors, and non-invasive health monitoring. These advances will establish a versatile manufacturing direction that delivers immediate impact across biomedical engineering, healthcare, defence, space, and telecommunications industries. This talk will present recent advances in additive manufacturing technologies and their transformative applications in antenna design. Particular emphasis will be placed on conductive and dielectric multimaterial 3D-printed antennas, as well as four-dimensional (4D) shape-reconfigurable antennas, where the fourth dimension “time” enables antennas to dynamically alter their geometry and electromagnetic performance in response to external stimuli. Biography: Yang Yang was born in Bayan Nur, Inner Mongolia, China, and received the PhD degree in Electronic Engineering from the Department of Electrical and Computer Systems Engineering at Monash University in 2013. From 2012 to 2015, he worked as a Global Service Plan Engineer with Rain Bird. In December 2016, Prof. Yang joined the University of Technology Sydney, Australia. He is currently a Professor in the School of Electrical and Computer Engineering at The University of Sydney, where he leads the research group in 3D Millimetre-Wave and Terahertz Circuits and Antennas. His research interests include additively manufactured electronics, millimetre-wave and sub-terahertz technologies for 5G and beyond, and biomedical applications. He has authored more than 300 international publications in the fields of microwave, millimetre-wave, and terahertz circuits and antennas. Prof. Yang is the Australian Research Council Mid-Career Industry Fellow (2025-2029). He was selected as one of the “Top 2 % Most Highly Cited Scientists by Stanford” every year since 2019. He received many distinguished awards, including the 2025 Advanced Materials Innovation Award by the International Association of Advanced Materials (IAAM), 2024 IEEE MTT-S IMS First Place in the Early Career Award Competition (serving as the ECR advisor), 2023 IEEE NSW Section Outstanding Service Award, 2023 IEEE AP-S Outstanding Chapter Award and 2022 IEEE MTT-S Outstanding Chapter Award. He is the current Track Editor of IEEE Transactions on Microwave Theory and Techniques, an Associate Editor of IEEE Microwave and Wireless Technology Letters (2024-2025), a Guest Editor of Proceedings of the IEEE (2024), an Area Editor of Microwave and Optical Technology Letters (2019-2024), an Associate Editor of IEEE Access (2018-2022), and a Guest Editor of IEEE Transactions on Antennas and Propagation (2026). Prof. Yang is the Inaugural Chair of IEEE MTT-S TC-17 Microwave Materials and Processing Technologies. He is a committee member of IEEE AP-S TC-8 Wireless Communication and IEEE MTT-S TC-28 Biological Effects and Medical Applications. During 2022-2024, he served as a member of the AP-S Technical Committee on Antenna Measurements and the AP-S Technical Directions Committee. His appointments at IEEE NSW Section, Region 10, include the committee member of the IEEE NSW Section, the Treasurer (2018-2019) and the Chair/Vice Chair (2020-2024) of the IEEE NSW AP/MTT Joint Chapter, the Secretary (2019) of IEEE NSW PH/ED/SSC/CAS Joint Chapter, the Inaugural Committee/Treasurer (2020) and Vice Chair (2022-2024) of IEEE NSW Electron Devices Chapter. He also volunteered in various conference organising committees, such as the General Co-Chair of the 2025 Australian Microwave Symposium, General Co-Chair (Executive Chair) of the inaugural annual international conference on IEEE Additively Manufactured Electronic Systems (AMES2025) and General Chair of IEEE MTT-S International Microwave Workshop Series on Advanced Materials and Processes for RF and THz Applications (IMWS-AMP 2026). He is the 2026 Secretary of the IEEE Microwave Theory and Technology Society.
