摘要

覆盖范围广，对噪声的敏感度低，数据收发能力强，延迟低，基于物联网的大规模应用，以及连接性的增加，使得6ghz以下成为5G普遍使用的频段。然而，由于越来越多地使用sub-6 GHz频段而产生的大量有害电磁辐射所引起的健康问题引起了研究人员的注意。本文提出了一种宽带、极化、斜角不敏感的超材料吸收器，吸收带宽为1.9 GHz，从3.1 GHz延伸到5 GHz，覆盖5G分配的n77、n78和n79频段。该设计包括环，分裂环和弯曲交叉偶极子负载集总电阻的组合。采用准静态方法设计了等效电路，并对设计进行了制作和测量。在sub- 6ghz范围内分配的整个5G频段中，证明了所提出的吸收器可以减少电磁辐射和比吸收率。

Wide-band metamaterial absorber for sub-6 GHz 5G applications: Reducing specific absorption rate

Wide coverage area, less sensitivity to noise, high data transceiving, low latency, IOT-based mass application, and increased connectivity make sub-6 GHz, a popularly used frequency band for 5G. However, the health issues due to the high amount of harmful electromagnetic radiation generated from the growing usage of the sub-6 GHz band have drawn the attention of researchers. This article presents a wide-band, polarization, and oblique angle insensitive metamaterial absorber with an absorption bandwidth of 1.9 GHz stretching from 3.1 to 5 GHz, covering bands of n77, n78, and n79 allocated for 5G. The design consists of combination of rings, split rings, and meander-crossed dipoles loaded with lumped resistors. The equivalent circuit is designed using a quasi-static approach and the design is fabricated and measured. The proposed absorber is demonstrated for the reduction of electromagnetic radiation and specific absorption rate in the entire 5G band allocated in the sub-6 GHz range.
