摘要
为了满足实际的应用需求,提出设计了一款小型化软质薄膜UHF频段RFID标签天线。天线的构形采用了典型的T形匹配结构,并且根据实际要求将尺寸控制为70mm×17mm。利用HFSS天线仿真软件对所设计的天线进行仿真分析,得出的结果图表明该标签天线的回波损耗值及方向性均良好,说明其与特定的标签芯片之间有良好的阻抗匹配特性并且天线具有良好的辐射特性。天线的结构以及厚度还有其良好的工作特性说明其可以很好地满足实际生产和应用的具体要求。
To satisfy the practical requirements,the paper proposes the design of a miniaturized soft film UHF band RFID tag antenna.The configuration of the antenna utilizes a typical T-shaped matching structure,and according to the practical requirements we control the size of the antenna as 70 mm×17 mm.We have used HFSS antenna simulation software to simulate and analyze the antenna,the results show that the tag antenna has a good impedance matching with the tag chip,and the antenna has good radiation characteristics.The configuration and good work characteristics of the antenna can satisfy the practical requirements of production and application.
