SSPS activities at Japan Space Systems

Abstract

  Japan Space Systems (J-spacesystems) has been studying wireless power transmission (WPT) since the beginning of 2000 as a key technology for the realization of future Space Solar Power System (SSPS). From 2014, we have started new research and development project of the Microwave Power Transmission under the contract of Ministry of Economy, Trade and Industry (METI). In this program, we have developed high power amplifiers with high efficient GaN HEMT, and the high efficient rectenna element. In this paper, status of this project is introduced.
