Contact UsTape Deployable high-Gain Reflectarray (“T-DaHGR”) Antenna
MMA’s DaHGR Antennas enables a range of high-performance systems packaged in small stowed volumes. Our DaHGRs are configurable and feature both wideband and narrowband architectures.
The T-DaHGR antenna architecture is realized using very lightweight flexible membrane substrates, tensioned via tape spring, where the prefix “T” denotes the Tape-tensioning method.
The solution builds on innovations by MMA in extremely lightweight deployable systems specific to large antennas and aerobraking systems. The T-DaHGR antenna combines the best attributes of successfully flown solutions, but with advantages in performance, compaction and simplicity, and significantly reduces the development and implementation risk by leveraging proven technologies. A large, space-fed reflectarray provides bandwidths achievable by reflectarrays, and can be configured to support larger bandwidths, to easily support a multitude of mission requirements.
Key Characteristics:
- Cassegrain and prime offset-fed reflector configurations
- UHF-Ka band
- 20+% bandwidth
- 1.0 – 50+m² aperture
- Up to 1+m²/U packing efficiency
- 1U+ volume
