Completed TRL 2 (started at 2, targeting 4)
We are developing a class of planar antennas consisting of a textured surface or metasurface (MTS) on a thin support. The antenna aperture is divided in panels, which are folded in the CubeSat chassis during launch and deployed when the CubeSat reaches the desired orbit. The developed high-performance MTS antenna will be light-weight, low-profile, and will have integrated feed structure. In addition, the novel MTS design will lead to an efficient on-surface control of the aperture fields and, hence, to low-level of cross-polarized fields and beam-shaping capabilities.
One of the main advantage of the antenna we are developing compared to other technologies such as deployable mesh reflectors and reflectarrays lies in having the feed on the aperture plane, which eliminates the complexity associated to the feed deployment. This translates into the possibility of having larger apertures and, hence, higher gains. With this development, NASA will have flat high-gain antennas available for future CubeSats and SmallSats telecommunication systems. This high-gain antenna system is flat, has low-mass, and is much easier to implement and lower-cost compared to phased array technology.
The technology developed here will enable NASA to field low-profile, low-weight, and high gain antenna system for space comminication systems.
The flat antenna development could be used for future telecommunication antennas.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
