中文摘要：

异向介质的发现是电磁学发展史上的重要事件，具有重要的科学意义和应用前景。本文采用新型边开口谐振环异向介质作为天线的覆盖层，并用AnsoftHFSS软件进行仿真。仿真结果表明，采用异向介质后，天线的谐振频率向低处移动了0．1GHz，回波损耗减小了12dB，天线的阻抗匹配更佳。同时，加载异向介质后天线的增益提高了1．1dB，半功率波瓣宽度减小了7度。

英文摘要：

The discovery of the metamaterials is a significant event in the development of electromagnetism. It is of great scientific significance and application prospect. The metamaterials based on the side open loop resonators is used as the cover of microstrip antenna. Simulation by the Ansoft HFSS shows that by using metamaterials, the resonance frequency reduces by 0.1GHz and the echo loss decreases by 12dB. It indicates that the antenna＇s impedance matches better. At the same time, the gain of the antenna, increases by 1. ldB and the lobe by 7 degrees.
