用于电子商务物流业务电子标签的双频分形天线
内容简介：电子标签（RFID）依托射频通信技术实现非接触式自动识别，在电子商务的物流业务上被广泛的应用。天线在RFID系统中具有重要的地位，天线设计及制造技术是RFID的核心关键技术之一。针对RFID系统双频工作的要求，设计了两款能够双频带工作的π型分形折叠偶极子天线，使其能够同时覆盖现代电子商务物流RFID系统常用的两个工作频段：0.902～0.928 GHz和2.4～2.4835 GHz，且在两个工作频段都有较好的性能，分别仿真并测试了两款天线的回波损耗和方向图特性。
Abstract：Radio frequency identification(RFID)technology achieves non-contact automatic identification by using RF com-munication technology. It has been widely used in E-commerce logistics business. The antenna plays an important part in RFID system. Antenna design and manufacturing technology are important for RFID system. Aiming at the dual- frequency running re-quirements of the RFID system,two kinds of dual-frequency π-type fractal folded dipole antennas were designed,which can cover two common frequency bands of 0.902~0.928 GHz and 2.4~2.483 5 GHz of modern E-commerce logistics RFID system. Both of them have good performance. The return loss and direction diagram characteristics of two antennas were simulated and measured respectively.
