A new design concept of a wideband radar absorbing structure consisting of load-bearing glass/MWCNT added epoxy composite and having low density/lightweight characteristics for C- to X-band and X-to Ku-band radar is presented. The proposed radar absorbing structures have triple layers which are the low density and light weight layer to reduce the total weight, covering layers to protect the foam layer from humidity absorption, and a load-bearing layer as the actual structural layer. The proposed designs satisfied -10 dB absorption in the C-band to X-band and X-band to Ku-band using only two different materials. Moreover, from a practical point of view, since thickness control of absorbing structures is an important factor for the absorbing performance, the proposed structures could minimise fabrication errors (precise thickness controls) by employing multiple layers for wideband absorbing performance.
