An ultra-thin and ultra-wideband anisotropic metasurface, acting as a linear polarization converter through reflection is designed and simulated in this research. The operation frequency range covers almost completely the Ku-band and the entire K- and Ka-band. The unit cell of the proposed metasurface is composed of a arrangement of concentric square metallic loops on a grounded dielectric substrate, in which a diagonal split is made, providing properties of an anisotropic material. Simulation results show that an efficient cross-polarization conversion, both for normal as well as for oblique incidence, is achieved with $ -10 $ −10 dB fractional bandwidth of 98.7% from 13.8 GHz to 40.7 GHz and with an average polarization conversion ratio of 97.5%. The ultra-wideband of the proposed structure results from multiple plasmonic resonances occurring at three neighboring frequencies (15.2 GHz, 25.9 GHz, and 38 GHz) resulting in a significant expansion of the operating frequency range. |
