Hey there,

If you're looking for prices, lead times and any other information for components, subsystems or services, submit a free tender with preliminary specifications, and suppliers will respond to you:


The Antenna System for 6/12U CubeSats design is based on the hugely successful ISISPACE deployable antenna system for 1U up to 3U CubeSats. This system has been redesigned from a more modular approach, to fit into 6/12U structures while, at the same time, providing the same capabilities. The antenna system allows the same options in antenna configuration such as 4x monopole, 2x dipole, 1x turnstile. Other configurations such as hybrids between dipole and monopole are also available that can cover from the VHF to UHF frequency ranges and they are deployed under user command.

Antenna main beam gain:

UHF: 0 dBi

VHF: 0 dBi

Max RF Power: 2W


UHF: >50 Mhz (-10db bandwidth)

VHF: >10 Mhz (-10db bandwidth)

Antenna element deployment duration: <3s at 15°C

Mass: 90-115g (depends on configuration)

Envelope stowed (l x w x h): 98x98x6.6mm3

Antenna length

UHF: 17cm average

VHF: 55cm average

Power consumption o Nominal: < 30 mW o During deployment: < 2.3W

Interfaces: o Electrical: Miniature 9 pin OMNETICS connector o Data: I2C

RF input/output: MMCX female 50 ohm

Operational temperature range: -20°C to +80°C

RF Antenna configurations

Single/multiple monopoles (UHF and/or VHF)

Single/dual dipoles (UHF and/or VHF)

Combination of monopole and dipole o UHF or VHF turnstile

Supply voltage 4V to 17V

RF Harness length and connector type and orientation (MMCX, MCX, SMA)

Customization and simulation on request
