Abstract :This paper presents a wideband, thin, low-cost, and easy to fabricate linear polarization insert ignore into journalissuearticles values(LP); converter design utilizing metasurface insert ignore into journalissuearticles values(MS); for Ku-band insert ignore into journalissuearticles values(12-18 GHz); applications insert ignore into journalissuearticles values(also in the 18-19 GHz part of the K-band insert ignore into journalissuearticles values(18-27 GHz););. The design has a topology on a 1.6 mm thick FR-4 dielectric material with copper MS on the front and an entirely copper slab on the back. The presented design shows a polarization conversion ratio insert ignore into journalissuearticles values(PCR); of beyond 90% within the 12-19 GHz frequency band and also over 99% in the 12.5-13.1 and 16.32-17.64 GHz frequency ranges. To further give insight into the physical structure of the suggested MS-based polarization converter insert ignore into journalissuearticles values(PC);, both the u – v axes are analyzed, and the existing surface behaviors at resonance frequencies are investigated. We compare the performance outputs with other Ku-band PCs, and the efficiencies of the suggested strategy over current MS-based LP converters are emphasized.
