In this letter, a reflective metasurface composed of double-layer metallic L-patterns is designed. Both the simulated and measured results demonstrate that when the incident angle ranges from 0 degrees to 30 degrees, the metasurface can be regarded as a three-band polarization converter. On the one hand, the metasurface can convert TM (TE) polarized incident wave into right (left)-handed circularly polarized wave from 9.1 to 16.5 GHz as well as left (right)-handed circularly polarized wave from 20.0 to 25.4 GHz. On the other hand, the metasurface can realize cross-polarization conversion between TM and TE polarized waves from 17.4 to 18.9 GHz. In addition, the transmission model is expanded from monolayer reflective metasurface to multilayer reflective metasurface to explain the conversion mechanism whose theoretical results are highly consistent with the simulated and measured results.
