We report a wideband and wide-angle insensitive linear cross-polarization converter based on an anisotropic metamaterial. The converter structure consists of a periodic array of a top metallic crescent-shaped resonator and a bottom metallic ground plane separated by a dielectric layer of FR-4. Both simulation and experiment methods have performed to evaluate the proposed polarization converter performance. The results show a good agreement between the simulation and experimental results. The polarization converter efficiency above 90% is obtained for a wide bandwidth of 6 GHz covering the entire Ku-band (12–18 GHz) at normal incidence. Furthermore, the wideband polarization conversion properties are maintained with a large incident angle up to 45° for both transverse electric (TE) and transverse magnetic (TM) modes. Hence, the designed structure can be used for Ku-band applications.
