摘要

本文分析了三种类型的后向散射无线电阅读器天线，并提出了一种测量天线后向散射信号的方法，该方法涉及使用一个连接到消声室的网络分析仪，该消声室有或没有接收天线。我们分析了工作频率为1.8 GHz的线偶极子和工作频率为900 MHz的微带偶极子两种类型的反向散射信号。实验结果表明，与微带偶极子相比，接收天线偶极子线对后向散射信号的反射效果更好。偶极子天线具有比宽带微带天线更高的增益，可以作为后向散射无线电阅读器的良好选择。

Performance analysis of antennas for backscatter radio reader

This paper presents an analysis of three types of antennas for backscatter radio reader and a method for measuring backscattering signal from antennas which involves using a network analyzer connected to an anechoic chamber with and without the receiving antenna. We analyzed the backscattered signals of two types of dipole: wire dipole at the operating frequency 1.8 GHz and microstrip dipole operating frequency of 900 MHz. The experimental results showed that the receiving antenna dipole wire showed a better reflection of the backscattered signal compared to the microstrip dipole. The dipoles presented higher gain than broadband microstrip antenna, can be a good options for backscatter radio reader.
