Novel wire grid embedded C-sandwich radome structures for broadband airborne applications

摘要

The application of symmetric wire grid structures for the broadbanding of C-sandwich radome panel, with core thickness optimized for power transmission, is presented. The performance parameters of wire grid embedded C-sandwich wall are evaluated based on equivalent transmission line method. The superior broadband EM performance of wire compensated C-sandwich wall is established based on a comparative study with the conventional structure at normal incidence and at a high incidence angle often encountered in streamlined airborne radomes.
