BeetleSat Expandable Ka-band Parabolic Antenna
NSLComm (BeetleSat)
BeetleSat's 60 cm deployable Ka-band parabolic antenna stows into 2U of a 6U CubeSat and deploys in orbit via shape-memory polymer — achieving up to 2 Gbps throughput; first-ever in-orbit deployment from a nanosatellite confirmed May 2023 on BeetleSat-1 at 550 km SSO.

About
The BeetleSat Expandable Antenna is NSLComm/BeetleSat’s patented deployable Ka-band reflector — a lightweight (≈140 g) foldable parabolic dish made from proprietary shape-memory polymer that stows compactly inside just 2U of a 6U CubeSat and deploys fully in orbit to a 60 cm aperture. The antenna includes a FlexoSub adaptive sub-reflector that dynamically shapes and steers the beam footprint, enabling beam optimization without mechanical gimbals. Demonstrated on NSLSat-1 (2019) and fully proven in a world-first deployment on BeetleSat-1 / NSLSat-2 (launched January 2023 on SpaceX Falcon 9, deployment confirmed May 2023) in sun-synchronous orbit at approximately 550 km, the antenna achieved two-way Ka-band data communication at up to 2 Gbps — more than 100× the throughput of conventional nanosatellite antennas. A NISSAN (Nano ISS Antenna) technology demonstration experiment flew on the International Space Station with the Axiom-1 crew in April 2022, confirming antenna deployment and shape measurements in a microgravity environment. The antenna architecture forms the backbone of BeetleSat’s planned 250–264 satellite Ka-band LEO constellation targeting mobile network operator backhaul, defense, aviation, and maritime markets, with commercial service planned from 2026–2027. The constellation will cover latitudes ±65°. NSLComm/BeetleSat is an Israeli New Space company and built the BeetleSat-1 satellite in partnership with Clyde Space (UK).
