Basic Learning of Antennas and Propagation
Organizer / Chair :   Tomohiro Seki (Nihon Univ.)
The history of terrestrial mobile communications starting with pagers is surprisingly old, and the fundamental concept of antenna propagation in the fifth generation (5G) remains unchanged. However, in order to cope with high speed and multimedia, operation frequency increase and bandwidth expansion are essential, and technical progress has been made to improve processing speed and software. As a result, apparent scatterers (people, buildings, etc.) became larger, and the propagation characteristic resolution improved. In the fifth generation mobile communication system, it is necessary to work closely with active beam technology that utilizes this technology advance, cognitive and MIMO technology.
In this lecture, I begin with the basic design concept of mobile communication antenna/propagation research, and introduce the latest application technology. I will also briefly mention terminal antennas and describe further design points of antenna systems in mobile communications, which will become important in the future of people's lives.
