摘要
在电子标签的印制中,采用分层印刷电子标签天线的思路,提出了分层蝶形天线模型,并进行了仿真模拟,研究了墨层厚度对蝶形天线辐射效率的影响。由仿真结果分析可知:不同区域电流密度的高低影响分层天线的辐射效率,在天线上找到了分层最佳点,分层天线的辐射效率比单层天线高。解决了印刷天线墨层厚度与辐射效率矛盾的问题。
A layered-printed RFID antenna idea and layered butterfly antenna model were put forward for RFID printing.Simulations were carried out and the influence of ink thickness on radiation efficiency of butterfly antenna was studied.Simulation results showed that the current density in different area has influence on radiation efficiency;there is a best point on the antenna which can improve the radiation efficiency of layered antenna higher than single-layer printed antenna.The problems of contradiction between ink thickness and radiation efficiency can be solved through optimization.
