RADOMES DESIGNED FOR SPECIFIC APPLICATIONS
We take an iterative and proven approach to radome design and analysis. First, we draw upon our experience to determine an initial radome configuration that is likely to meet your requirements. Second, we then optimize the design using high fidelity electromagnetic and structural analysis. Next, accurate 3D CAD, Finite Element Analysis, and Computational Fluid Dynamics models are used to predict lift, drag, and overturning forces under the specified environmental conditions. Lastly, the forces placed upon the radome structure by environmental loads from wind, ice, snow, and shock are applied to the structural analysis to achieve a structurally compliant design with adequate safety factors to ensure we meet your needs.
Typically, we supply A-sandwich, C-sandwich and solid laminate radome configurations. The configuration chosen is dependent on the application and performance requirements of the antenna system.
A-sandwich configurations are made up of three dielectric layers consisting of a low dielectric core with thin fiberglass skins on both sides. A-sandwich configurations provide excellent cost/performance benefits at lower frequencies. The thicknesses of the core material and skins are adjusted as necessary to achieve optimum RF performance while maintaining adequate structural integrity.
C-sandwich configurations are made up of five dielectric layers with two layers of core separated by three layers of fiberglass. C-sandwich configurations display better RF performance at higher frequencies, but are more expensive due to complexity in the analysis and manufacturing processes. Like in an A-Sandwich construction, the thicknesses of the core materials and skins are also adjusted as necessary to achieve optimum RF performance and adequate structural integrity.
Solid laminate configurations are constructed using a number of structurally sufficient layers of fiberglass or other materials. We have provided solid laminate solutions of up to 30ft (9.1m) in diameter.
