In this study, a novel microwave absorber which consists of a structural part, a resistive sheet, and a lowdielectric layer is proposed. Unlike the conventional Salisbury screen, a newly proposed absorber is capable of a rangeof absorbing performance, from narrowband to broadband. In the case of the narrowband absorber, the fabricatedabsorber with optimized design parameters has a strong resonance at 9.25 GHz and reflection loss of .44 dB withsatisfying the .10 dB absorption in whole X-band (8.2 GHz~12.4 GHz). For the broadband absorber design, thereflectivity was minimized in the considered frequency ranges. The designed absorber showed two weak resonancesnear 6.5 GHz and 16.5 GHz and satisfied the .10 dB absorption from C-band to Ku-band (4 GHz~18 GHz). Themeasured reflection loss of fabricated absorber was well matched with simulation results, though the measurement wasonly performed on X-band. For the Salisbury screen to be capable of broadband absorption, it should be stackedmultiply in a structure known as the Jaumann absorber. However, for the microwave absorber presented here,broadband as well as narrowband capabilities can be implemented without a change of the structure.
