A mantle cloak with a novel unit cell design is proposed for the scattering suppression of cylindrical metasurfaces. The proposed cloak is designed for an electrically small cylindrical object. The Mie Theory is employed to calculate the surface impedance of the mantle cloak, which plays a critical role in determining the optimal design parameters. The unit cell parameters necessary for the design are obtained by analyzing the surface impedance. Bistatic Radar Cross-Section (RCS) analyses have been conducted for the cloaked and uncloaked cases of cylinders. The designed cylinder demonstrated remarkable scattering suppression at the operating frequency. Furthermore, the results obtained from the novel unit cell design are compared with findings in the literature, underscoring the improved cloaking performance achieved with the new design. As a demonstration, a single-layer novel unit cell cloaked cylinder is constructed with a total radius equal to 13 percent of the free-space wavelength, a total length corresponding to 1.94 times the free-space wavelength, and a dielectric spacer thickness of 1.27 percent of the free-space wavelength. This single-layer novel unit cell mantle cloak achieves a 16.65 dB total RCS reduction at 3.1 GHz, with a notable decrease in scattering at the operational frequency in all directions.
