摘　　要：通过将矩形环分形天线嵌入到左手材料中,形成一种基于左手材料的矩形环分形微带天线。采用有限元法对该复合天线进行分析和仿真,发现基于左手材料的矩形环分形微带天线在各频段增益明显增大,同时具有较低的回波损耗和电压驻波比,实现了较好的匹配性,且有效地改善了天线的性能。由此可以看出基于左手材料的矩形环分形微带天线在移动通信、卫星通信以及航空航天等领域具有潜在的应用价值。In this article,the fractal rectangular ring antenna is embedded in the left-handed material to compose a fractal rectangular ring microstrip antenna based on the left-handed material. The finite element method is used to analyze and simulate the composite fractal antenna. It is found that the proposed antenna has a higher gain at different frequencies with a relatively low return loss and voltage standing wave ratio,favorably matching with single chips and improving the antenna＇s performance parameters. The proposed antenna has potential applications in such fields as mobile communications,satellite communications,and aerospace.
