讲座人介绍

Jiro Hirokawa received the D.E. degrees in electrical and electronic engineering from Tokyo Institute of Technology, Japan in 1994. He is currently a Professor there. From 1994 to 1995, he was with the antenna group of Chalmers University of Technology, Gothenburg, Sweden, as a Postdoctoral Fellow. He received Tokyo Tech Award for Challenging Research in 2003, Young Scientists' Prize from the Minister of Education, Cultures, Sports, Science and Technology in Japan in 2005, Best Paper Award in 2007 and a Best Letter Award in 2009 from IEICE Communications Society, and IEICE Best Paper Award in 2016 and 2018. He is a Fellow of IEEE and IEICE.

讲座内容

This speech presents the rectangular coordinate orthogonal multiplexing (ROM) antenna system for non-far region communication. ROM uses beam orthogonality in the rectangular coordinate system. The orthogonality based on polarity relating to the symmetry of the antenna structure gives wideband operation and the extension to two-dimensional orthogonality is easy. These features would be advantageous in comparison with OAM transmission based on the orthogonality in the cylindrical coordinate system in microwave and millimeter-wave areas. The feasibility is discussed on one system, where a corporate-feed waveguide slot array antenna and a monopulse circuit are combined. 4-multiplexing 40cmcommunication using 16x16-slot arrays are confirmed experimentally in 80GHz band.
