A single-layered broadband linear-linear reflective type polarization converter is proposed in this article. The top patch comprises a 45° tilted novel H-shaped dipole printed on a 33.5μm thin polyamide substrate grounded on the other side. The design exhibits a minimum 90% Polarization Conversion Ratio (PCR) over 0.64 THz (0.67-1.31 THz) bandwidth and 64.65% Fractional Bandwidth (FBW). The motivation lies in this converter's design exhibiting near-unity conversion at 1 THz. The structure shows a stable broadband response up to 40° for both Transverse Electric (TE) and Transverse Magnetic (TM) modes with a bandwidth reduction of up to 30% without compromising the cell's performance. The proposed unit cell is compact with the structural periodicity of 0.188λL and thickness 0.075λL, where λL is the free-space wavelength corresponding to the lowest frequency of the broadband. The authors strongly believe that the proposed design possesses features like compactness angular stability, making this design suitable for applications where the reflective type linear-cross polarization conversion is the primary need. © 2022 IEEE.
