摘　　要：近年来提出的新型人工电磁结构(metamaterial)凭借其特有的电磁属性成为国际物理、材料和电磁领域的研究前沿和热点。将人工电磁结构作为系统的一部分加载到天线中,将大大改善微带天线的近远场特性,给微带天线的物理尺寸、制造成本和性能指标等方面带来突破,有利于促进新型微带天线在通信系统中的应用。文章首先简要介绍了新型人工电磁结构的概念及其发展历史和现状。然后重点分析总结了新型人工电磁结构在微带天线中的应用,分别从新型人工电磁结构在小型化微带天线中的应用、新型人工电磁结构在多频多模微带天线中的应用、新型人工电磁结构在波束控制微带天线中的应用以及新型人工电磁结构在微带天线其他方面的应用几个方面进行详细阐述。最后,展望了新型人工电磁结构未来在微带天线中的应用前景。With the unique electromagnetic properties, metamaterial has become a hot point among physics, electromagnetics and material science research nowadays. With the metamaterial as part of the antenna structure, the near and far field characteristics including the physical size, fabrication cost and the performance index can be improved, which also contributes to the appli- cation of the novel antennas in communication systems. Firstly the concept, the history and the condition of the metamaterial were introduced briefly. Then special stress was laid on the analysis of microstrip antennas based on metamaterial structures including meta-based miniaturization an- tennas, meta-based multi-band multi-mode antennas, meta-based beam-controllable antennas and meta-based other kinds antennas. Finally, future application of the meta-based antennas was pre- dicted.
