摘要
研究一种新型夹层电磁带隙结构微带天线。首先分析这种电磁带隙结构的带隙特性,然后设计一个基于该电磁带隙结构的矩形贴片天线,并进行仿真实验。仿真结果表明,该结构的微带天线能有效地抑制天线表面波的传播,其增益比普通贴片天线提高了1.9dB,回波损耗小于-10dB的带宽增加了38.5%。
A novel microstrip antenna with sandwich EBG structure is studied in this paper.The EBG characteristics are analyzed and a rectangular patch antenna design with this structure is presented with simulation results. The results show that this kind of structure suppresses surface waves effectively and enhances the antenna gain by 1.9dB as compared with that of a normal rectangular patch antenna,besides the-10dB bandwidth of return loss is increased by 38.5%.
