The microwave absorption properties of single-wall carbon nanotubes (SWNCTs) and barium ferrite nanocrystalline (SWCNT/BaFe12O19) composites with different doping ratios are investigated in the frequency region of 2–18 GHz. The transmission line theory is used to calculate the reflection loss properties, and microwave absorptive mechanism of the SWCNT/BaFe12O19composites is discussed. The experiment results reveal that the microwave absorption properties of composite are very sensitive to the volume percentage of SWCNTs. Owing to the multiple absorptive mechanisms, the microwave absorption properties of composite are evidently improved. When SWCNTs are doped with 6 vol % of the sample volume, the maximum reflection loss of the SWCNT/BaFe12O19composite with a 3 mm thickness reaches 30.79 dB at 10.5 GHz, and the range of resonance absorption peak below -10 dB is about 6 GHz.
