Completed TRL 5 (started at 3, targeting 5)
The antenna system on a small satellite is a critical component, as a failure of the antenna can lead to mission failure. Present antenna systems are typically wire 'whip' antennas that are fragile, prone to breakage, and are quite protrusive from the CubeSat body. The main objective of this research is to replace these off-the-shelf whip antennas with low-profile transparent microstrip antennas that are integrated into the frame of the CubeSat body, directly over the solar panels. The low-profile designs will not protrude from the CubeSat surface by more than 5 mm, and will be mechanically durable.
The antennas resulting from this work will be low profile and integrated direction onto the CubeSat frame, giving much better reliability and compactness in the CubeSat design. This new approach to CubeSat antenna design is expected to result in a major paradigm shift in the way CubeSats are designed. Making the antennas reconfigurable will allow for the same antennas to be used for different frequency bands and different polarizations, making the CubeSats a versatile as possible. This will allow for next-generation communication capabilities that do not yet exist for CubeSats.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 5) — 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.
