| Summary: | In this paper, we propose a high-efficiency and wide-bandwidth linear polarization converter using double U-shaped metasurface. The design is based on the two dimensional artificial electromagnetic materials and micro-antenna array. Theoretical analysis and simulation results show that the proposed polarization converter can realize the orthogonal polarization transformation for the reflected electromagnetic wave, the conversion bandwidth is 6.91-14.31GHz and the polarization conversion ratio is above 90%. Additionally, the measurement results have good agreement with the simulation data. The proposed double U-shaped structure not only has a simple geometry but also can realize the wide bandwidth and high efficiency conversion. Hence it can find wide applications in novel polarization-control devices. |
