Abstract

In this contribution we analyse the read probability enhancement using two simple dual-antenna techniques for passive RFID tags for Tyre Pressure Monitoring applications. Our analysis is based on real-world channel measurements carried out with a full vehicle body for different antenna and steering angle configurations. Two frequency ranges were analysed: European UHF band at about 866 MHz and 2.45GHz ISM band. Two antenna combining methods were investigated: Antenna selection and power combining. With the latter a read probability enhancement from 49% to 75% is achievable.

双天线轮胎压力监测RFID标签的双频信道增益统计

在这篇文章中，我们分析了使用两种简单的双天线技术用于轮胎压力监测应用的无源RFID标签的读取概率增强。我们的分析是基于真实世界的信道测量，在不同的天线和转向角度配置下，对整个车身进行测量。分析了两个频率范围:欧洲UHF频段约866 MHz和2.45GHz ISM频段。研究了两种天线组合方法:天线选择和功率组合。使用后者，可以实现从49%到75%的读概率增强。
