The multifunctional metasurface achieves low insertion loss and high polarization conversion in specific frequency ranges, suggesting broad applications in radar stealth.
In this brief, a multifunctional metasurface combining frequency selective surface (FSS) and polarization converter is presented. A novel structure integrating anFSS and a polarization converter is introduced, which is cascaded with a low‐frequency polarization converter to form a frequencyselective polarization converter (FSPC). The FSPC achieves a flat transmission window with an insertion loss of less than 1 dB in the frequency range of 8.7–10.7 GHz, while achieving polarization conversion bands (polarization conversion ratio > 90%) across the 4.7–6.7 GHz and 13.6–6.3 GHz frequency ranges. The structure also demonstrates angular stability within a range of 30°. A four‐port equivalent circuit model is employed to analyze the proposed FSPC. Furthermore, the checkerboard arrangement effectively reduces backward scattering within 4.7–15.4 GHz. A prototype was fabricated and experimentally validated, with test results showing good agreement with simulation results. The design shows promising application prospects in radar stealth systems.
