| 摘 要： | 为了获得具有高增益特性的天线，对传统透镜天线工作原理进行了分析。因为透镜天线板间电场模式与波导中电场模式类似，以此为依据通过改变金属透镜的金属平板间距和板脊高度，设计了一种新型金属透镜天线，迥异于传统金属透镜天线的凹形曲面结构。该天线金属透镜由多片长方形侧面加脊金属板组成，能够很好地调节口径面的相位分布，以此实现口径面同相分布，从而获得高增益性能。

| Abstract: | Analyzing the working principle of traditional lens antenna can know the electric mode between metal plates is similar to that of waveguide. A new metal lens antenna is designed through changing the distance between metal plates and changing the heights of ridge. It is different from traditional metal lens antenna with concave surface structure. This metal lens antenna is composed of a plurality of rectangular metal plates with ridge on the side. This new lens antenna can adjust the aperture to make the phase distribution consistent, and therefore it can obtain high gain characteristic. |
