摘要
提出了一种基于EBG结构的天线系统截面优化方案,采用EBG结构代替以往常用的λ/4反射腔结构,可以使天线系统截面高度大大缩减。并对背面加载EBG结构的阿基米德螺旋天线辐射特性进行了仿真分析,仿真结果表明EBG结构可以代替反射腔结构使天线具有单向辐射特性。
This paper introduced an optimized method of low - profile antenna based on electromagnetic band - gap structure. Utilization of an EBG structure greatly reduces the height of low - profile antenna, including the thickness of the EBG structure, instead of the traditional λ/4 Cavity backing implementation of spiral antennas. Then Archimedean spiral antenna with EBG structure is simulated by Ansoft HFSS. According to the simulation results, the antenna with EBG structure has single radial characteristic instead of the traditional λ/4 cavity.
