设计了一种基于尺寸渐变超表面的宽带高增益低剖面天线，该天线由双层超表面和一层微带缝隙组合而成。双层超表面由分别印刷在 2个介质板上的尺寸渐变六边形阵列贴片组成,贴片之间存在非等距间隙。超表面单元尺寸渐变设计能够使天线产生多个邻近的谐振点，从而展宽带宽。通过改变超表面天线尺寸结构，分析天线的宽带辐射特性。为获得最佳宽带性能，采用遗传算法优化天线几何参数。制作并测试了一款边长为 43.3 mm，厚度为 4.853 mm的样本天线用于验证仿真结果。实测结果显示，该天线-10 dB阻抗带宽达到了 54%(3.99~6.93 GHz)，最高增益达到 12.05 dB，在 4~6 GHz范围内增益保持在 8 dB以上。该天线实现了宽频带、高增益、低剖面的特点，适用于宽带高速率无线通信的诸多领域。
