A recently granted patent (Publication Number: US11894606B1) discloses a novel radome structure designed for electromagnetic applications. The radome structure comprises multiple core layers with varying dielectric constants, including a central core layer, interior and exterior intermediate core layers, and interior and exterior outside core layers. These layers are composed of woven fiber cloth impregnated with a matrix binder, with specific dielectric constants ranging from 1.5 to 8.5. Additionally, the structure includes syntactic foam layers formulated with microballoons and fillers embedded in a matrix binder to achieve the desired dielectric constants and thickness.

Furthermore, the patent outlines a method for manufacturing the radome structure, involving the provision of core layers with specific dielectric constants and compositions. The method includes the use of woven fiber cloth impregnated with a matrix binder, syntactic foam layers with microballoons and fillers, and the application of environmental and protective coatings. The manufacturing process ensures the tailored balance of structural reinforcement and tuned electromagnetic performance, with core layers ranging in thickness from 0.005" to 0.5". Overall, the patented radome structure and manufacturing method offer a unique approach to designing radomes for applications requiring precise electromagnetic properties and structural integrity.
