摘要
This study focused on the radome and proposed an absorber with a meta-dome structure for ultra-wideband radar absorption using an FR-4 dielectric material on the metasurface absorber for protection. In addition to protecting the absorber, the metasurface absorber exhibited ultra-wideband frequency absorptivity from radar signals, with an absorptivity band from 4.6-12 GHz, including the C and X frequency bands of radar signals. A wide incidence angle should also be considered in addition to the absorption frequency band. Experimental results were obtained for all polarization angles at normal incidence for 5-14 GHz. Sensitivity to incident angle from 0 degrees to 40 degrees in the transverse electric mode and 0 degrees to 60 degrees in the transverse magnetic mode were observed. The proposed concept was demonstrated using full-wave simulation and experimental measurements.
