Carbon fiber satellite communication antennas provide higher performance

The new carbon fiber composite satellite communication antenna from the Calian SED is designed to provide improved performance by reducing structural distortions that may be caused by conventional ground systems consisting of steel or aluminum.

On May 6, Calian Group Ltd. (Saskatchewan, Canada) Systems Engineering (SED) introduced a new line of medium and large diameter RF (RF) antennas made of carbon fiber composites. The lightweight antenna system is said to be the result of years of research and development of composite materials and high performance antenna designs by Calian SED. With more than 30 years of experience in advanced RF ground systems, the company has designed composite carbon fiber antennas to meet the emerging needs of customers of advanced RF ground systems.

As satellite communication networks evolve to higher frequency ranges, such as Q and V bands, the technical challenges of satellite RF terrestrial systems are increasing. At these higher frequencies, environmental factors such as rain, wind, and uneven heating of the antenna surface can degrade signal performance. Calian SED’s new composite carbon fiber satellite communication antenna is designed to improve performance by reducing structural distortions that may be caused by conventional ground systems consisting of steel or aluminum.

“With the support of the Canadian Space Agency, the European Space Agency, the Dominion Radio Astrophysics Observatory, the Canadian National Research Council Industrial Research Assistance Program and the innovative design team of the Calian SED Research Organization, we are able to make the necessary innovations. President of Cadence SED Patrick Serra said that the establishment, identification and commercialization of this breakthrough technology. “These antennas have made significant advances in RF antenna design and performance. ”

Currently equipped with a 10 m or 6 m high performance composite carbon fiber reflector and back structure, this design minimizes thermal, wind and gravity load distortion and provides improved performance in all frequency bands (including Q / V range and above) . The lightweight reflector design offers the added benefit of quick installation and reduced shipping weight – a key factor in reducing deployment costs. Calian SED said it plans to introduce additional aperture sizes in the future.
