摘要

本文提出了一种具有增强隔离性的超薄且位置非常近的双频频率选择表面(FSS)。单元电池由两个典型的同心圆六边形环组成，内环的每一侧都装有几个存根。通过存根负载配置，相邻谐振腔的相互耦合得到了高度解耦，实现了非常紧密的频带间距和较好的隔离，两个工作频带的比值可低至1.06。此外，由于谐振频率独立，可以在1.06-2.43的范围内设置频带比。此外，为了更好地理解所提出的FSS的潜在机制，开发和分析了相应的等效电路模型(ECM)。通过样机验证了设计的有效性，实测结果与仿真结果吻合较好。

A single layer and very close band spacing frequency selective surface with enhanced isolation

An ultrathin and very closely located dual-band frequency selective surface (FSS) with enhanced isolation is proposed in this letter. The unit cell consists of two typical concentric hexagon rings, with several stubs loaded on each side of the inner ring. Through the stub-loaded configuration, the mutual coupling of adjacent resonators is highly decoupled and a very close band spacing FSS with better isolation can be achieved, and the ratio of the two operating bands can be as low as 1.06. Additionally, due to the independent resonant frequencies, the band ratio can be set over a wide range, from 1.06–2.43. Furthermore, the corresponding equivalent circuit model (ECM) is developed and analyzed for better comprehension of the underlying mechanisms of the proposed FSS. The validity of the design is then checked with a prototype, and the measured results show good agreement with the simulated ones.
