一种小型化蓝牙印刷天线的设计

The Design of a Miniaturized Bluetooth Printed Antenna

基于曲流技术,设计了一个覆盖整个ISM频段(2.4—2.484GHz)的小型化的印刷蓝牙天线。通过CST Microwave Studio软件对天线的阻抗和辐射特性进行仿真分析,得到了优化后天线结构参数。并制作了天线实物进行了测试。该天线尺寸仅有15mm×6mm×1mm,具有体积小、质量轻、全向辐射等优点,能够满足各种蓝牙系统的设计需求。

Based on the meandering technology,a miniaturized printed Bluetooth antenna covering the whole ISM band （2.4-2.484 GHz） is designed.The impendence and radiation characteristics of the antenna is analyzed by the software CST Microwave Studio,its volume is only 15 mm×6 mm×1 mm,thus the optimized parameters of the structure of the antenna is concluded.The proposed antenna with small size,light weight and omni-directional radiation is realized and tested,it can meet the require of all kinds of Bluetooth system。
