[Development Case] Antenna for Asteroid Exploration Rover

Introducing a case where image data was successfully transmitted to the asteroid explorer "Hayabusa2."

We would like to introduce a case where we developed an "antenna for asteroid exploration rovers." As background, there was a request for the development of an antenna to be used for communication between the "asteroid exploration rover" and the Hayabusa2 spacecraft. As a solution, we selected substrate materials that meet environmental conditions and aimed to minimize thickness, reduce profile, and lighten weight, thereby mitigating the impact of vibrations during launch and enabling placement in the gaps between solar panels. [Development Overview (Partial)] ■Challenges - Shape and material that meet the specific conditions of the rover - Resistance to space environment ■Results - Coverage of -5 dBi or more in frequency characteristics and polarization at ±90 degrees or more *For more details, please refer to the related links or feel free to contact us.
