提出了一种基于频率选择表面（FSS）的超材料结构设计的紧凑高性能屏蔽外壳。外壳有大孔，方便气流和电缆的接入。然而，它可以通过保持40 dB以上的衰减来获得良好的屏蔽性能。盾构由n ×× n个单元格组成，每个单元格由通过过孔相互连接的2.5维环型元件编织而成。该设计具有减小尺寸、扩展带宽和提高屏蔽效能的良好性能。此外，FSS上的扩大孔有助于通风和散热。所提出的2.5维FSS尺寸仅为0.097λ0λ0××0.097λ0λ0，其中λ0λ0对应共振频率的自由空间波长。该结构提供3.38 GHz （3.21-6.59 GHz）宽屏蔽带宽。此外，它对0 ~ 85°的广角入射波有稳定的响应，在4.83 GHz时x偏振和y偏振衰减均大于40 dB。所提出的FSS对于第五代（5G）无线系统、WiMAX和WLAN的屏蔽实际上是有用的。
A compact and high-performance shielding enclosure designed by metamaterial structure based on frequency selective surface (FSS) is proposed. The enclosure has large holes for convenience of airflow and cable access. However, it can achieve great shielding performance by maintaining more than 40 dB attenuation. The shield is composed of n ×× n unit cells, and each unit cell is designed by knitting the 2.5-dimensional loop-type elements interconnected through vias. This design shows promising capability of size reduction, bandwidth expansion, and shielding effectiveness enhancement. Moreover, the enlarged holes on the FSS are helpful for the ventilation and heat dissipation. The size of the proposed 2.5-D FSS is only 0.097λ0λ0××0.097λ0λ0, where λ0λ0 corresponds to free space wavelength of resonance frequency. The proposed structure provides 3.38 GHz (3.21–6.59 GHz) wide shielding bandwidth. Furthermore, it has stable response to the wide-angle incident wave ranging from 0∘∘ to 85∘∘ with more than 40 dB attenuation at 4.83 GHz for both x-polarization and y-polarization. The proposed FSS is practically useful for the shielding of fifth generation (5G) wireless systems, WiMAX, and WLAN.
