Isoflux Antennas

Quadrifilar Helix Antennas

Description

Our range of quadrifilar helix antennas, available in both deployable and fixed versions, is well-suited for a variety of space applications requiring an isoflux radiation pattern. These antennas are designed to ensure a consistent distribution of radio frequency (RF) energy across a specific coverage area, thereby maintaining reliable signal strength and quality between satellites and ground-based stations. This uniform signal distribution is particularly beneficial for applications such as data transmission, LEO-PNT (Position Navigation and Timing), IoT (Internet of Things), and more.

In cases where your satellite space is limited, our deployable antennas offer a mast-based technology with an excellent stowed-to-deployed ratio. Our antennas are versatile, covering a range from UHF to S-band frequencies.

Our antennas meet rigorous space standards for thermal and mechanical robustness and undergo a qualification campaign involving thorough testing for vibration, shocks, and thermal vacuum cycling. Additionally, we provide the flexibility of customized acceptance tests to meet your specific requirements.

Please note that our quadrifilar helix antennas are not a COTS (Commercial Off The Shelf) product. They are custom-made upond demand, hence why we do not have a generic datasheet to provide.
