This work presents a broadband linear-cross polarizer for K and Ka-band applications. The design consists of a simple asymmetric widths based meander-line metasurface printed on a thin FR-4 grounded-dielectric substrate. Normal incidence demonstrates 90% Polarization Conversion Ratio (PCR) Bandwidth (BW) of 20.64 GHz from 18.31 to 38.95 GHz with 72.1% Fractional Bandwidth (FBW). Due to the destructive interference involved at greater oblique angles, reflective polarizers experience severe degradation of 90% PCR BW response. The proposed polarizer is obliquely stable up to 43° for Transverse Electric (TE), 45° for Transverse Magnetic (TM) incidence with a lesser 90% PCR BW reduction of only 13.95% (TE) and 15.25% (TM) compared to normal incidence.
