Fabrication of Radar Array Antennas Using Large-Area, High-Resolution Lithography-on-Flex, Phase II

As the important role of NASA "missions to earth" has been clearly demonstrated in recent years, the need for radar antenna systems that have large fields of coverage has gained increased emphasis. In order to achieve the desired performance from space, the antenna systems must have surface areas that are hundreds of square meters in size. However, to make it affordable to deploy such large-area antennas into space, it is necessary to fabricate these antennas on flexible substrates, which are lightweight, and can be rolled into small volumes. The fabrication of flexible antennas calls for new manufacturing techniques that are capable of addressing the challenges of patterning high-resolution features on very-large area flexible substrates, while achieving precise registration of the antenna features over the entire substrate area. In this Phase II proposal we will develop and demonstrate processes to fabricate large-area antennas on flexible substrates, focusing, in particular, on JPL's 2 x 3 m active membrane phased array radar; and we will fabricate the flexible panels required for JPL's antenna. The fabrication of the array antenna will be performed using Anvik's novel large-area roll-to-roll photolithography technology, which enables high-resolution and micron-level registration on large-area flexible substrates.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
