摘　　要：提出了几种不同周期性单元的PBG结构的贴片天线。采用有限元法对其进行仿真分析,通过相互对比,研究出这几种不同PBG结构对贴片天线性能的影响。结果表明,在贴片天线中增加PBG结构能减少天线的回波损耗,提高天线的增益和辐射效率。并得出周期性单元的形状和数目对其特性的影响。In this paper,several patch antennas based on different periodic cell photonic bandgap structures are proposed.The method based on finite element was used to analyze those different antennas,and we get some results about the influence of different photonic bandgap structure to the patch antenna by compared with each other.We found that its input return losses were reduced,the radiation efficiency was higher and its gain was improved in the patch antenna by adding the PBG structure.And it also contains that the shape and number of periodic cell influenced the properties.
