面向RFID应用的几种2．45GHz微带天线的分析比较

摘要

With the wide use of RFID, microstrip antenna has become the indispensable part in RFID, common microstrip antennas have single dipole and double dipole antennas. Based on the current application of RFID, some on-board antennas based on 2.45 GHz are put forward. The structures are analyzed combining with the the basic theory of antenna. This paper discusses the advantages and disadvantages of various microstrip antennas through the analysis of the simulation results which generated by using simulation software HFSS. It provides suggest for the application of RFID.%随着RFID的广泛应用，微带天线已经成为RFID中不可缺少的一部分，常见的微带天线有单偶极子和双偶极子天线。根据目前RFID的应用，提出了几种基于2．45GHz的板载天线，同时结合天线的基本理论对这几种结构进行了分析，并通过HFSS软件进行仿真比较。通过对仿真结果的分析，讨论了各种微带天线的优缺点，为RFID的应用提供了参考。
