We demonstrate a wideband polarization rotator with characteristics of high efficiency and large-range incidence angle by using a very simple anisotropic reflective metasurface. The calculated results show that reflection coefficient of cross polarization is larger than 71% over an octave frequency bandwidth from similar to 4.9 GHz to similar to 10.4 GHz. The proposed metasurface can still work very well even at incidence angle of 60A degrees. The experiment at microwave frequencies is carried out and its results agree well with the simulated ones.
