摘要
提出一种超材料频率选择表面结构,可以提高超宽带天线的增益,解决超宽带天线辐射效率低、反向辐射损耗大的问题。圆形贴片微带天线具有超宽带的辐射特性,作为反射面的频率选择表面位于超宽带天线介质基板的正下方,超材料单元以5×6方式排列于反射面的上表面。所设计的超材料频率选择表面结构具有超宽的频率带隙特性,置于超宽带天线下方,提高了天线的辐射效率,仿真结果表明在原天线的工作频段范围内,具有反射面的超宽带天线比原天线增益平均提高了3.28 dB。天线整体结构尺寸小且易于集成,可应用于使用超宽带技术的小体积便携式移动通信设备中。
In order to solve the problem of low radiation efficiency and reradiation loss,a metamaterial FSS structure is designed to improve UWB antenna gain in this paper.The microstrip antenna with circle patch has ultrawide radiation characteristics.The FSS structure is a reflection surface under the substrate of the UWB antenna,and the metamaterial units are arranged in 5×6 matrix on the reflection surface.The proposed metamaterial FSS structure with ultrawide frequency bandgap is located in the bottom of UWB antenna to enhance antenna radiation efficiency.The simulation result shows compared with original antenna,the average gain has been increased by 3.28 dB.The overall structure is small and liable to integration for portable mobile communication equipments with UWB technology.
