摘要：
To miniaturize the perfect metamaterial absorber, a fractal three-order oblique cross dipole slot structure is proposed and investigated. The fractal perfect metamaterial absorber (FPMA) consists of two metallic layers separated by a lossy dielectric substrate. The top layer etched a three-order oblique fractal-shaped cross dipole slot set in a square patch and the bottom one is a solid metal. A prototype with a thickness of 0.0106. (lambda is the wavelength at 3.18GHz) of the FPMA is designed, fabricated, measured, and is loaded on a 1x10 guidewave slot array antennas to reduce the in-band radar cross section (RCS). Experiments are carried out to verify the simulation results, and the experimental results show that the absorption at normal incidence is above 90% from 3.17 to 3.22GHz, and the array antennas significantly obtain the RCS reduction without the radiation deterioration.
