Aperture-type and patch-type frequency selective surfaces (FSS) were prepared by using carbon fiber paper containing carbon fiber. Using honeycomb as the matching dielectric layer, microscopic characterization of carbon fiber distribution in carbon fiber paper was performed by stereo microscope, the reflectivity of the composite FSS structure was tested by a vector network analyzer. The influences of unit shape, carbon fiber content in carbon fibre paper and carbon fiber length on the wave absorbing performance of aperture type FSS and patch type FSS were studied with the same matrix area ratio of carbon fiber paper. The results show that in the range of 2-18 GHz, the absorbing properties of aperture-type FSS and patch-type FSS are related to the content and length of carbon fiber in carbon fiber paper, and has nothing to do with the shape of the unit. At 6-18 GHz, with the same the ratio of the matrix area of carbon fiber paper, the shape of unit, the length and content of carbon fiber in the carbon fiber paper, the absorbing properties of aperture-type FSS are better than that of patch-type FSS.
