摘要
该研究提出了一种由方形分裂环(SRR)单元构成的超表面隔板结构,该结构可降低工作于X波段的两个Vivaldi天线之间的干扰耦合。采用等效媒质理论,分析了超表面结构介电常数和磁导率的单负特性,从而引起的带阻效应。与相距为30mm的参考无耦合天线相比,加载超表面后的天线隔离度在10GHz处提升了16dB。此外,仿真结果同样证实了,加载论文提出的超表面结构后,天线的辐射方向图、峰值增益以及总效率均得到了有效提升。
In this paper,a super-surface clapboard structure consisting of square split ring(SRR)elements is proposed,which can reduce the interference coupling between two Vivaldi antennas operating in the X-band.Based on the equivalent medium theory,the single negative characteristics of permittivity and permeability of the super-surface structure are analyzed.Compared with the reference uncoupled antenna with a distance of 30 mm,the isolation of the antenna is increased by 16 dB at 10 GHz.In addition,the simulation results also confirm that the radiation pattern,peak gain and overall efficiency of the antenna are effectively improved after loading the proposed super-surface structure.
