摘要

本文设计了一种基于超表面的高频扫描天线。本文提出的天线由三部分组成:1 × 16不等分频器、16个BJ900波导和160个超表面。该天线采用覆盖周期性超表面的标准波导BJ900馈电。工作频段为76-81 GHz。为了实现二维波束扫描，设计了不等分频器。经过最后的优化，仿真结果表明，二维工作角均为30°，辐射效率可达-0.1 dB。该天线的总实现增益可达20 dB。

Two Dimension Frequency Scanning Antenna

In this paper, a high-frequency frequency scanning antenna based on metasurface is designed. The antenna proposed here consists of three parts: an 1 × 16 unequal divider, 16 BJ900 waveguides and 160 metasurface. The proposed antenna is fed by a standard waveguide BJ900 with periodic metasurface covered on it. The working band is 76–81 GHz. To realize two-dimension beam scanning, an unequal divider is designed. After the final optimization, we can get from the simulation results that the working angle is 30° in both two dimension and the radiation efficiency can reach -0.1 dB. The total realized gain of the antenna can reach 20 dB.
