【摘要】：在当今的社会,随着科技和经济的发展进步,单纯的互联网已经不能满足社会发展的需求,新一代网络物联网应运而生。它作为互联网的下一代网络,是互联网的进一步延伸。在这个过程中,RFID射频识别技术在其中起着至关重要的作用。它作为一个纽带,将物体与网络连接起来。所以说RFID射频识别技术是现代物联网研究之中非常重要的一个环节。本文在对微带天线的理论知识进行了学习掌握,在了解了 RFID射频识别技术的相关内容的基础之上,对RFID系统中的天线技术进行了研究与设计。本次设计包括了读写器的天线设计以及电子标签的天线设计。在对圆极化天线的实现方式总结的基础上,我对经典的方法进行了融合,开拓了新的思路。本篇文章的主要内容包括了三大部分:第一部分,首先对本次研究的意义进行了说明并对现如今发展情况进行简单的介绍。然后就是对这次我们研究的两种RFID天线所涉及到的一些理论和知识进行总结。第二部分,则是在对RFID读写器天线的相关理论知识进行分析总结后设计了三款读写器天线。其中前两款是对两种经典圆极化结构的融合,第三款是双频圆极化天线,它是在多次分析实验过后,选定了一款易于实现圆极化的结构进行多频化设计。第三部分,则是在对RFID电子标签天线的相关理论知识分析的基础上,对多种结构进行比对,最终设计出了一种位于超高频段的电子标签天线。这款天线采用的是弯折偶极子结构,阻抗匹配采用的是电磁耦合的方式。由于现在还未出现适用于微波频段的电子标签芯片,所以文章最后对在微波频段的无源标签天线进行了探索性的设计。
[Abstract]:In today's society, with the development and progress of science and technology and economy, the simple Internet has been unable to meet the needs of social development, the new generation of Internet of things came into being. As the next generation network of the Internet, it is the further extension of the Internet. In this process, RFID radio frequency identification technology plays a vital role. As a link, it connects objects with the network. So RFID radio frequency identification technology is a very important link in the research of modern Internet of things. This paper has mastered the theoretical knowledge of microstrip antenna, and on the basis of understanding the related internal capacity of RFID radio frequency identification technology, the antenna technology in the RFID system The design includes the design of the antenna of the reader and the antenna design of the electronic label. On the basis of the summary of the realization of the circular polarization antenna, I have merged the classical methods and opened up a new idea. The main contents of this article include three parts: first, this is the first part The significance of the study is explained and the present development situation is briefly introduced. Then, some theories and knowledge involved in the two kinds of RFID antennas we have been studied are summarized. The second part, after analyzing and summarizing the relevant theoretical knowledge of the RFID reader and writer antenna, designs the three reader antenna. The first two sections are the fusion of two classical circular polarization structures, and the third is a dual frequency circular polarization antenna. After several analysis experiments, it selects a multi frequency design which is easy to realize circular polarization. The third part is on the basis of the analysis of the theoretical knowledge of the phase correlation of the RFID electronic tag antenna. An electronic tag antenna is designed at ultra high frequency section. This antenna uses a bending dipole structure, and the impedance matching is used in electromagnetic coupling. Since there is no electronic tag chip for microwave frequency band, the paper has been used for passive tag antenna at microwave frequency band. Exploratory design.
