摘要

电磁带隙(EBG)结构自发展以来一直受到射频和微波工程师的极大关注。由于其独特的特性，如零相位反射和表面波抑制，它们已被用于设计高效天线和许多其他应用。本文简要回顾了EBG结构的三种最新应用，即抑制地面反射噪声(GBN)或抑制同步开关噪声(SSN)，降低雷达横截面(RCS)和降低比吸收率(SAR)。通过在混合信号系统的功率平面上打印EBG结构，实现了SSN降低- 60 dB。通过在RCS中嵌入贴片天线，实现了高达20 dB的衰减。与没有任何EBG加载的相同天线相比，移动电话天线的SAR降低了84%。当无线体域网络(WBAN)天线与EBG结构集成时，也观察到其SAR的大幅降低。

Electromagnetic Band Gap Structure Applications in Modern Wireless Perspective: A Review

Electromagnetic Band Gap (EBG) Structures are of great interest among RF and microwave engineers since their development. Because of their unique characteristics like zero phase reflection and surface wave suppression, they have been used for design of efficient antennas and numerous other applications. This article briefs a review of the three state of the art applications where EBG structures have been utilized namely: Ground Bounce Noise (GBN) suppression or Simultaneous Switching Noise (SSN) suppression, Radar Cross Section (RCS) reduction and Specific Absorption Rate (SAR) reduction. SSN reduction up to −60 dB is achieved by printing EBG structures on power plane of mixed signal system. By embedding the EBG structures with patch antenna up to 20 dB reduction in RCS is realized. Up to 84% reduction in the SAR of a mobile phone antenna is obtained as compared to same antenna without any EBG loading. Substantial reduction in the SAR of a Wireless Body Area Network (WBAN) antenna is also observed when integrated with EBG structures.
