超材料板材及由其制成的超材料天线罩和天线系统
摘要：
本发明涉及一种超材料板材，其包括一超材料片层，所述超材料片层包括两基板和置于所述两基板之间的结构层，所述结构层包括多个金属微结构，每一金属微结构包括一圆环、两连接于所述圆环且位于所述圆环的同一直径方向上的第一金属直线段和两分别垂直地连接于所述两第一金属直线段且相互平行的第二金属直线段，所述两第一金属直线段分别连接于相应第二金属直线段的中点，从而使其对电磁波的反射变小、透波性能提高，减小了对天线的辐射波的影响，这样可维持天线的原有增益和其方向图主瓣形态。本发明还提供了一种由该超材料板材制成的超材料天线罩和天线系统。
摘要（英）：

The invention relates to a metamaterial plate which comprises a metamaterial piece layer. The metamaterial piece layer comprises two base plates and a structural layer arranged between the base plates, wherein the structural layer comprises multiple metal microstructures. Each metal microstructure comprises a circular ring, two first metal straight-line segments connected to the circular ring and located in the same diameter direction of the circular ring and two paralleled second metal straight-line segments perpendicularly connected to the first metal straight-line segments respectively. The first metal straight-line segments are respectively connected to midpoints of the corresponding second metal straight-line segments, accordingly the reflection ratio of the first metal straight-line segments to electromagnetic waves is decreased, the wave-transparent performance is improved, and the influence on radiation waves of an antenna is reduced. Therefore, the original gain of the antenna and the major lobe form of a directional diagram can be maintained. The invention further provides a metamaterial antenna housing and an antenna system made of the metamaterial plate.
