ISISPACE's VHF/UHF antenna for 6U+ platforms is a configurable deployable antenna subsystem for 6U-and-larger CubeSats and microsatellites.

The ISISPACE VHF/UHF Antenna for 6U+ is a deployable very high frequency (VHF) and ultra high frequency (UHF) antenna for CubeSats of 6U and larger and for microsatellites. It is a modular evolution of ISISPACE's 1U-3U antenna, built from two corner printed circuit boards, a radio frequency (RF) phasing board and tailored harnesses.[1] ISISPACE also names it Antenna Subsystem 2 and reports flight heritage since 2020 with more than 100 units.[1]

It can be configured as a monopole, dipole, turnstile or hybrid antenna, with circular or linear polarisation. Elements can deploy automatically or individually, and the antenna has safe/arm control and telemetry.[1] ISISPACE advertises Automatic Identification System (AIS) and LoRa capabilities and identifies the antenna with IRIDE constellation applications.[1]

The published frequency range is 145-868 MHz, with 0 dBi gain on both VHF and UHF and 2 W RF power handling. Bandwidth at -10 dB exceeds 50 MHz at UHF and 10 MHz at VHF.[1] Deployment takes less than five seconds. Consumption is 80 mW nominal and less than 2.3 W during deployment.[1]

Mass is 90-115 g and the footprint 98 x 98 mm, with a configuration-dependent height. The interfaces are a nine-pin OMNETICS connector, Inter-Integrated Circuit (I2C) and a female 50-ohm MMCX RF connector.[1] The operating temperature range is -20 to +80 C and the deployment temperature range -5 to +80 C.[1]

Qualification includes functional, thermal-vacuum, thermal-cycling and vibration tests; acceptance includes functional and thermal-cycling tests.[1]
