RF Design, Analysis and Testing
Our engineered SHEERGARD® RF materials are designed to provide excellent hydrophobicity and RF transmission. They are then tested and analyzed to provide peak performance in tough, real-world applications.
Extremely robust, yet thin and flexible, SHEERGARD® RF transparent materials are band agnostic and designed to provide superior RF transmission performance and permanent hydrophobicity. Tested and analyzed for applications like air-supported radomes, electromagnetic windows, antenna covers, and other special structure configurations – in challenging environments worldwide.
Communications technologies like 5G, mmWave, IoT, and LEO Internet have higher operating frequencies than their incumbent technologies. They carry more data at faster speeds to a greater number of users but also cause structural challenges the infrastructure must overcome. SHEERGARD® fabrics are optimized for high-frequency systems, with a high-strength Kevlar or fiberglass construction and dielectric constants of less than 2.8 and loss tangents below 0.008. Band agnostic, they operate excellently at high incidence angles. And their blended fluoropolymer matrix not only prevents water accumulation but also actively encourages rain to slide off the surface. They are tested during rain events and offer optimal and permanent hydrophobicity. SHEERGARD® sandwich radomes are electrically designed and their performance is validated through independent testing.
Saint-Gobain Composite Solutions is a long-trusted partner for creating highly specialized, technology-driven material solutions that deliver extraordinary performance across a spectrum of demanding settings. Through collaboration with our customers, we co-develop versatile materials and real application tests to ensure that you have the best possible solution for your application. We help create innovative materials that provide protection, easy release, insulation, and friction control. And we seek to collaborate in making it even more possible.
Rigorous testing standards
Saint-Gobain Composite Solutions rigorously tests all SHEERGARD® radome products via software-modeled analytics, lab-scale material characterization, and most importantly, directly relevant application testing. Every SHEERGARD® radome complies with strict MIL.STD.810 testing – the military-leading standard for all environmental conditions including temperature, humidity, salt, fungus, and many more. Software modeling such as Finite Element Analysis and Thermal Analysis can yield information on deflections, factors of safety, and thermal management requirements. Application tests such as physical hail storm testing, destructive fabric testing, and real-life application exposure reveal key learnings in creating a truly optimized product. Our testing begins during the co-development process to develop relevant tests and gather data that allows us to create market-ready solutions quickly.
