该文提出了一种加载超表面(MetaSurface,MS)的宽带低剖面双极化交叉偶极子天线.天线由三部分结构组成:1对交叉偶极子、4个寄生贴片和超表面结构.交叉偶极子用于实现天线的双极化特性.通过在交叉偶极子上方加载寄生贴片和在偶极子臂处开槽,扩展了天线的阻抗带宽.同时将交叉偶极子下方的金属反射板替换为超表面,实现了天线的低剖面.为了提高馈电端口间的隔离度,引入了4个金属短路柱.仿真和测试结果表明,天线

In this paper
a broadband low-profile dual-polarized cross-dipole antenna loaded with a metasurface (MS) is proposed. The antenna is consisted of three parts: a pair of crossed dipoles
four parasitic patches
and a metasurface structure. The crossed dipoles are used to achieve dual-polarization characteristics of the antenna. By loading parasitic patches above the dipoles and slotting the dipole arms
the impedance bandwidth of the antenna is extended
and the low profile of the antenna is achieved by replacing the metal reflector below the dipole with a metasurface. In order to improve the isolation between the input ports
four metal shorting columns are introduced. The simulation and measured results show that the impedance bandwidth of
