摘　　要：为实现天线的柔性可穿戴和多频特性,采用毛毡作为介质基板,引入Durer 5边分形天线结构和电磁带隙(EBG)结构,采用锥形微带作为馈电,并利用全波电磁仿真软件HFSS建模仿真和参数优化,天线在3.56、3.76、4.67、5.62、6.6、7.89、9.90 GHz处的回波损耗值都低于-10 dB.此外,通过建模对天线在靠近人体模型和发生形变时的工作特性对比分析,验证了天线在靠近人体以及弯曲情况下的稳定性.证明该天线实现了可穿戴性和多频特性.In order to achieve a flexible,wearable and multiband antenna,the substrate is made o feltis,the Durer Pentagon fractal antenna structure and the electromagnetic band gap(EBG)structure has been used,and the tapered microstrip feed is adopted..Modeling simulation and parameter optimization of antenna by using full wave electromagnetic simulation sofware HFSS,the results show that the return loss of the antenna in 3.56,3.76,4.67,5.62,6.6,7.89,9.9 GHz values are less than-10 dB.In addition,the stability of the antenna near the human body and the bending condition are verified by comparing the working characteristics of the antenna near the human model and the deformation.It is proved that the an-tenna is a wearable multiband antenna.
