The lab studies integrated circuits for wireless communication and wireless power transfer that extend into space.
AboutAbout the lab
Wireless technology reaching into space, and radios that need no power source.
The Shirane Lab studies integrated circuits for wireless communication and wireless power transfer.
To extend the reach of wireless communication into space, the lab builds radios and wireless ICs to be mounted on satellites.
Using wireless power transfer, which sends power by radio waves, the lab also aims to realize radios that need no power source.
As the power used for communication keeps growing, the lab works on research into wireless devices that are gentle on the global environment.
Key terms
- Integrated circuit
- An electronic circuit in which many components, such as transistors, are built together on a small chip. Also called an IC
- Wireless power transfer
- Technology that sends power to a distant device using radio waves or similar means, without connecting wires
- Satellite constellation
- A system in which many satellites work together to form, for example, a communication network covering a wide area of the Earth
- Millimeter wave
- Radio waves of very high frequency, used for high-speed wireless communication such as 5G

ResearchResearch themes
The lab studies integrated circuits that enable wireless communication extending into space and wireless power transfer. From radios mounted on satellites to power-source-free 5G radios on the ground, it works to advance wireless devices both in space and on Earth.
*Illustrative imageRadios for ultra-small satellites
Aimed at low-Earth-orbit satellite constellations, the lab studies compact, lightweight radios that work in space, in collaboration with researchers inside and outside the university and with companies. Some of this research involves arranging radios on a film that unfolds to a large size in space.
*Illustrative imageRadiation-hardened wireless ICs
Radiation in space gradually degrades wireless ICs. The lab studies radiation-hardened, low-power wireless ICs that keep working for a long time in the harsh space environment, even on a satellite's limited power.
*Illustrative imagePower-source-free 5G radios
The lab develops millimeter-wave 5G relay radios that run on wireless power transfer and need no power source. This makes 5G communication possible even in places that radio waves have not previously reached.
