The Square Kilometre Array (SKA), a global project with twelve member countries aims to answer fundamental questions about the origin and evolution of the Universe. This talk will start with an overview of Square Kilometre Array (SKA) project, including e.g. what is the SKA?, SKA science goals? SKA sites, operating frequency range, performance, schedule, cost, etc. Then, the research and development of SKA dish antennas are described. The key technology and challenges of the dish antennas are discussed. The optical and feed design, structural design, FEA analysis and the calculated efficiency, error beam of dish are also introduced. Finally, the schedule of dish prototype R&D is given.
Professor Dr. Biao Du received the B.S. Degree in electrical engineering from the Xidian University, Xi’an, China, in 1983, and the M.S. Degree from CTI (Communication Telemetry and Telecontrol Research Institute), Shijiazhuang, in 1987, and the Ph.D. degree in electronic engineering from Shanghai University, Shanghai, China, in 1996. From 1987 to 1995, he was an Antenna Engineer in the Antenna Servo Department, CETC 54 (The 54th Insititue of China Electronics Technology Group Coopration). From 1996 to 1998, he worked as a senior engineer. From 1999 to 2000, he was a visiting scholar in the Department of Electronic Engineering, City University of Hong Kong. Currently, he is a Professor, Chief Antenna Expert and the Deputy Chief Engineer of CETC 54. He is the Chief Designer of Shanghai 65-m Tian Ma radio telescope antenna and The Square Kilometre Array (SKA) Dish antenna. His research interests include
EDA Research Seminar Series (2016/17) satellite communication antennas, radio telescope antennas, corrugated horns, utral-wideband feeds, microstrip antennas, phased array antennas, etc. Dr. Du received the Bao Gang Education Award for the excellent students in 1995. He obtained the special allowance of China Govermant for his outstanding contribution in natural science in 2016. He also received five National Advancement Awards in Science and Technology, and published more than 60 papers. He has got more than 20 patents. He is a senior member of Chinese Institute of Electronics (CIE).
All members of staff are welcome to the seminar. RAs and postgraduate students are particularly encouraged to attend the event.The Seminar will be chaired by Professor Steven Gao.
