摘　　要：文章提出了一种新型的电磁带隙结构,该结构通过在贴片上面挖槽增大了电流在贴片表面上的路径。仿真比较新型EBG结构在微带阵列天线之间的3种不同排列方式对阵列天线降低耦合的影响,仿真结果显示,在中心频率为5.3GHz时,耦合减小了11.73dB,此新型电磁带隙结构具有明显的电磁带隙特性,可以有效抑制表面波,降低微带阵列天线间的相互耦合。A new type of EBG(Electromagnetic Band Gap) structure is proposed in this paper, which increases the path of current on the surface of the patch by slotting on the patch. By comparing the effect of three different arrangement modes of the new EBG structure on the array antenna coupling, the simulation results show that the coupling decreases by 11.73 dB at the center frequency of 5.3 GHz. The novel EBG structure has obvious electromagnetic bandgap characteristics, which can effectively suppress surface waves and reduce the coupling between micro strip array antennas.
