摘　　要：设计了一种双三角形谐振环结构的左手材料,通过理论计算和仿真实验证明了其具有电磁左手材料性质;将双三角形谐振环结构的左手材料加载在矩形贴片微带天线上,并给出了矩形微带贴片天线的结构参数;利用HFSS仿真软件对比了加载左手材料前后矩形贴片微带天线的性能,仿真结果表明,左手材料的加载提高了天线的带宽,增大了天线的增益,有效地抑制了旁瓣。The paper designed a kind of left-handed material with the structure of double triangles and resonance ring,and proved that material has properties of electromagnetic left-handed material by theoretical calculation and simulation experiment.It loaded the left-handed material with structure of double triangles and resonance ring on a rectangular microstrip patch antenna,gave structure parameters of the antenna,and compared performance of the antenna before and after loading the left-handed materials using HFSS simulation software.The simulation results show that the loading of the left-handed materials improves bandwidth of the antenna,increases gain of the antenna,and suppresses the sidelobes.
