This paper presents two new compact unit cells for single and dual broadband linear co to cross-polarization conversion. Two metasurfaces are printed on perfect conductor-backed dielectric substrate. The first unit cell consists of slotted rectangular patch with meander line at the center. The structure exhibits a broadband linear cross conversion from 10.63-22.27 GHz (11.64 GHz or 70.8 %) with a polarization conversion ratio (PCR) is > 90 %. The converter response is found incidence angle stable up to 38°. Periodicity of the unit cell is 0.43 λ0, where λ0 is free-space wavelength. A linear dipole is incorporated in the first structure to realize the second converter with dual broadband characteristics. The design shows PCR > 80% from 7.28-10.52 GHz (36.4 %) and from 17.44-24.13 GHz (32.2 %). © 2021 IEEE.
