HANT – Highly innovative antenna technologies for new space applications
In this project, the partners are developing an approach for modular antenna technology for use in low Earth orbit.
Project Partners
HPS GmbH, Fraunhofer ISC
Duration
22.10.2023 – 30.08.2025
Funding authority
Bavarian Ministry of Economic Affairs, Regional Development and Energy
Motivation
The HANT research project between HPS GmbH, Fraunhofer ISC, and TUM focuses on the concept development for a small, deployable antenna system concerning the requirements driven by the “new space” market. Individual components in development are not just aligned to a single antenna model; even common parts made of mesh and additively manufactured composites in lightweight construction or mold construction are identified to apply the principle of modularity to a comprehensive antenna family. The critical aspect is the combination of lightweight technology with mesh technologies for the reflective surface of the reflector, together with an innovative deployment mechanism, to realize a competitive development tailored to the global small satellite and satellite constellations. This promises cost savings in development and production.
Method
The main goal is the cost-effective and modular production of antenna connection components in lightweight construction. For this purpose, the structure is generated from PEEK using additive manufacturing. Different connection concepts regarding tensile strength, topology, and durability in low Earth orbit are being investigated. In addition, a tool (parabolic mold shell) with a low coefficient of thermal expansion is additively manufactured using a large-format 3D printer.
