研究一种新型的EBG结构在波导缝隙天线中的应用。这种新型的EBG具有可以有效抑制表面波的特性,提出了在阵面缝隙单元间加载EBG周期单元结构的方案,抑制波导缝隙天线之间的互耦。通过与传统的波导缝隙天线进行比较得出加载新型EBG结构的波导缝隙天线在互耦上有很大改善。
The application of a new type of EBG structure in waveguide slot antenna is studied. The novel EBG has the property of effectively suppressing the surface wave. A scheme of loading EBG periodic cell structures between the crevice cells is proposed to suppress the mutual coupling between the waveguide slot antennas. Compared with the traditional waveguide slot antenna, it can be concluded that the waveguide slot antenna with the new EBG structure is greatly improved in mutual coupling.
