On May 6, the System Engineering Department (SED) of Calian Group Ltd. (Saskatchewan, Canada) launched a new series of medium and large diameter radio frequency (RF) antennas composed of carbon fiber composite materials. 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.
With the development of satellite communication networks to higher frequency ranges such as Q and V bands, the technical challenges of satellite RF ground systems are increasing. At these higher frequencies, environmental factors such as rainfall, wind, and uneven heating of the antenna surface can degrade signal performance. Calian SED's new composite carbon fiber satellite communications antennas are designed to improve performance by reducing the structural distortion that traditional ground systems composed of steel or aluminum can generate.
"With the support of the Canadian Space Agency, the European Space Agency, the Dominion Radio Astrophysics Observatory, the National Research Council Industrial Research Assistance Program of Canada, and the innovative design team of the Calian SED research organization, we can make the necessary innovations. Patrick, President of Calian SED Sierra said the establishment, qualification and commercialization of this breakthrough technology. "These antennas have made significant advances in RF antenna design and performance. "
Currently equipped with 10-meter or 6-meter high-performance composite carbon fiber reflector and back structure, the design minimizes heat, wind and gravity load distortion and provides improved performance in all frequency bands (including Q / V range and above) . The lightweight reflector design has the added benefit of quick installation and reduced transport weight-a key factor in reducing deployment costs. Calian SED said it plans to introduce additional aperture sizes in the future.
