摘要：
In this paper, a novel structure of reflective circular polarizer for millimeter wave band is proposed, which can convert the linear polarization to the circular polarization in a wide band. The proposed reflection-type circular polarizer is a metallic grating consisting of mushroom-shaped elements. The grating profile and period are optimized to provide great converting performance. The simulation results show that the 1.2 dB axial ratio bandwidth is about 5.6 GHz. The designed grating circular polarizer features simple structure and wide bandwidth, which can be used for broadband transmission systems in the millimeter wave range.
