阅读说明：本技术 透镜、透镜天线、射频拉远单元及基站 (Lens, lens antenna, radio remote unit and base station ) 是由 罗昕 陈一 孔龙 于 2018-02-06 设计创作，主要内容包括：本申请提供了一种透镜、透镜天线、射频拉远单元RRU及基站。该透镜包括基材层和金属层；该基材层的至少一面是凹面或者凸面；该基材层的至少一面存在该金属层；该金属层包括金属部分和镂空部分,该金属部分或该镂空部分以图形阵列呈现；该图形阵列包括多个第一环形,该第一环形包括多个图形单元,多个该第一环形中尺寸较大的环形包围尺寸较小的环形；其中,相邻的两个该第一环形包括的多个该图形单元的尺寸、旋转角度,以及相邻的两个第一间隔中的至少一个不同,其中,该第一间隔为相邻的两个该第一环形之间的间隔。本申请提供的技术方案可以利用金属层使透射电磁波产生移相量,从而可以减少依靠改变基材层厚度产生移相量,减小基材层的厚度,进而减小透镜的厚度。(The application provides a lens, a lens antenna, a Radio Remote Unit (RRU) and a base station. The lens comprises a substrate layer and a metal layer; at least one surface of the substrate layer is a concave surface or a convex surface; the metal layer is arranged on at least one surface of the substrate layer; the metal layer comprises a metal part and a hollow part, and the metal part or the hollow part is presented in a graphic array; the graphic array comprises a plurality of first rings, each first ring comprises a plurality of graphic units, and the ring with the larger size in the plurality of first rings surrounds the ring with the smaller size; at least one of the size, the rotation angle, and two adjacent first intervals of the plurality of graphic units included in two adjacent first rings is different, wherein the first interval is an interval between two adjacent first rings. The application provides a technical scheme can utilize the metal level to make the transmission electromagnetic wave produce the phase displacement volume to can reduce to rely on changing substrate layer thickness and produce the phase displacement volume, reduce the thickness of substrate layer, and then reduce the thickness of lens.)
