To realise wide‐band stealth of radar absorbing material, a special‐shaped honeycomb radar absorbing structure within nested cone‐shaped scattering configuration is designed. Based on the HS theory and the impedance matching design, the rule about the influence of the geometry parameter and electromagnetic parameter on the absorbing performance is analysed. In addition, the reflectivity performance is analysed on the condition of oblique incidence angles. By optimising the geometry parameters of the special‐shaped honeycomb structure and designing the multilayer composite structure based on impedance matching theory, the results indicate that the two absorbing peaks can be formed for the special‐shaped honeycomb radar absorbing structure, and the reflectivity is improved for both the vertical and oblique incidence angles.
