A novel metal-only reflectarray element with double split square ring slot laser cut into a metallic thick stainless steel plate is proposed in this paper. By using this unified slot structure, the dielectric substrate usually used in traditional reflectarray designs can be removed. The proposed technique can provide a more than 400° phase range with relatively smoother slope. In order to verify the phase data, a 25°-beam-steering metal-only reflectarray operating at 12.5 GHz is designed and simulated. A 1-dB gain bandwidth of 12% is achieved, which is slightly wider than that of reflectarray designs consisting of conventional patch elements. The proposed metal-only structure can better withstand the extreme outer space environment and effectively reduce the antenna cost.
