| Summary: | We propose a broadband metasurface consisting of a novel compact resonator to achieve linear polarization conversion in reflection mode. This compact resonator is designed on Roger 5880 substrate, measuring 1.575 mm in thickness, and possessing a loss tangent of 0.004. This structure is also upheld by a metal ground. The described unit cell effectively sends back incoming waves by converting 900 across a wide range of frequencies. This unit cell presents an efficiency exceeding 90 % for polarization conversion in the following frequency regimes: 12.2–41.5 GHz for normal incident waves. At the same time, this design includes polarization conversion with 90 % efficiency in broadband from 12.5 GHz to 30.6 GHz for angularly polarized waves up to 300. Behind this broadband polarization transformation lies the concept of surface current distribution and a high impedance surface. Given the broad-spectrum coverage and high-efficiency polarization conversion capabilities, our proposal holds significant potential for a wide range of applications. |
