摘要
提出了一款用于集装箱上的超高频RFID标签天线。从实际制作角度详细分析了天线与金属板的不同距离和金属板不同尺寸对天线参数的影响。结果表明,通过适当选取天线与金属板的距离以及联系实际的使用环境,其阅读距离基本满足要求,并且金属板尺寸的增大,使天线的增益也随着增大,但对天线的匹配影响较小,适合集装箱上RFID标签天线的应用。
This paper presented a UHF RFID tag antenna used in container and analyzed the effect of the distance between antenna and metal plates and size of metal planes on antenna parameters in detail.It is demonstrated that by selecting the distance between antenna and metal planes and considering real environment properly,detection distance can meet requirement,and gain of the antenna will be enhanced as increase the size of metal plane,however there is a little effect on match of antenna.Therefore,the antenna is suitable for application as container RFID tag antenna.
