摘要：
A Ku band high gain reflectarray antenna was proposed based on metasurface. Firstly, adopting a "lantern meander-line" structure combined with an open square ring structure, a metasurface element was designed with a unit size of 0.3λ0. The simulation analysis results show that, the unit can achieve a phase shift range 520° and a better phase shift characteristics. And then, a ku band high gain reflectarray antenna was designed with the unit. The reflectarray antenna was designed with a caliber size 160.8 mm×160.8 mm(7.2λ0×7.2λ0), fed by a pyramidal horn. The simulation analysis results show that, the reflectarray antenna can achieve higher gain and aperture efficiency. At the same time, it shows a better performance in the uplink frequency band 14.0~14.5 GHz and the downlink frequency band 12.25~12.75 GHz in the satellite communication. And the practical testing results are agreement with the simulated results, verifying the effectiveness of the design of the reflectarray antenna. © 2021, Editorial Department of Transaction of Beijing Institute of Technology.
