新型电谐振人工异向介质抑制阵列天线单元间互耦

内容简介：基于电谐振原理和镜像原理设计了一种周期性接地边耦合SRRs(split ring resonators)结构的新型电谐振人工异向介质,进而将该人工异向介质应用于抑制微带阵列天线元间的互耦.与传统微带阵列天线中的用于抑制互耦的电磁结构相比,该人工电磁结构不仅体积小(厚度仅为0.005λ_0),而且能获得优异的阵列单元间互耦抑制性能(抑制度达16.8 dB).该研究成果表明人工异向介质在高密度高性能微带天线阵列设计中具有良好的应用潜能.

Abstract：Based on electric resonance principle and image theory,a new type of periodical grounded edge-coupled split ring resonator(SRR)structure is designed in this paper.Then the proposed metamaterial structure is used to suppress the mutual coupling between elements in microstrip array.Compared with the traditional structures for suppressing mutual coupling,the proposed metamaterial structure has not only small size(to be specific,a small thickness of 0.005 operation wavelength),but also the ability to suppress the mutual coupling with excellent performance(-16.8 dB).The obtained results indicate that the metamaterial has an enormous potential in designing compact and high-performance microstrip arrays.
