An ultra-thin and broadband absorber is proposed in this paper. It is composed of a periodic array of slotted metal loop-dielectric multilayered structure and the thickness of the absorber is only 3.4 mm. Moreover, the absorption at normal incidence is above 90% (S11 <-10 dB) in the frequency range of 7.8-22.2 GHz. The design results are verified using FEM and FDTD and the experimental results are also given. They are very consistent. Then, we analysed above results based on the anti-reflection and resonance theory.
