Abstract：Metasurface has opened an effective way to handle the polarization states of electromagnetic waves since their intrinsic parameters could be flexibly tailored. In this paper， a simple anisotropic metasurface is presented to realize the polarization manipulation of linearly polarized wave with high conversion efficiency in a wide frequency band. The presented simple metasurface is able to convert the linearly polarized incident wave into its orthogonal polarized reflected wave at the frequency range of 8.16～15.32 GHz. Both the simulated and experimental results demonstrate that the bandwidths of the polarization conversion ratio reach more than 90% with the relative bandwidths of 60%. The conversion mechanism of the polarization is discussed with the theoretical calculations and surface current distributions.
