The point:

Participation in the space demonstration theme of Innovative Satellite Technology Demonstration Unit 3

Beamforming technology realizes an array antenna on a soft, uneven film

Developed a highly storable 5G compatible satellite radio using origami technology

Overview:

Tokyo Institute of Technology: JAXA

-Innovative satellite technology demonstration No. 3-

As a space demonstration theme, we will develop a phased array radio that supports 5G.

This research is part of “Demonstration of lightweight membranes and deployable structures with power generation and antenna functions” for Society 5.0.

5G compatible phased array radio development:

High power generation of small satellites
Large capacity communication
Contributes to higher performance such as high-resolution observation
Research team at Tokyo Institute of Technology:

The research team will be in charge of “development of a phased array radio that can be installed on a deployable membrane” as “artificial satellite technology for 5G millimeter-wave bands.”

Phased array radio:

The antenna element attached on the film surface
By changing the radiation direction of radio waves,
The flatness of the film after unfolding is electrically compensated.
OrigamiSat-1 Membrane Deployment Technology:

It uses the membrane deployment technology onboard the OrigamiSat-1, a microsatellite developed by Associate Professor Kosakamoto.

Millimeter-wave band beamforming technology:

The beamforming technology of the millimeter-wave band phased array radio developed by Professor Okada and Assistant Professor Shirane will be integrated.

If this technology is realized, it will be possible to mount a large antenna on a small satellite.

The Internet will be realized using the constellation of small satellites.
