Pantograph Deployable High-Gain Reflectarray (“P-DaHGR”) Antenna
MMA’s DaHGR Antennas enable a range of high-performance systems packaged in small stowed volumes. Our DaHGRs are configurable and feature both wideband and narrowband architectures.
The P-DaHGR antenna architecture is realized using very lightweight, flexible membrane substrates, tensioned via a pantographic mechanism, where the prefix “P” denotes the Pantograph-tensioning method.
The P-DaHGR antenna solution 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 equivalent performance as a conventional parabolic reflector for all missions not requiring extremely large bandwidth. Bandwidths achievable by reflectarrays easily support a multitude of mission requirements.
Key characteristics:
- Prime offset-fed reflector configurations
- UHF – Ka band
- 5 – 10+% bandwidth
- 1m² – 20m² aperture
- Up to 0.4m²/U packing efficiency
- 6U+ volume
