摘要
射频识别（RFID）系统在交通、物流货运、lT业生产、设备监控以及服务行业等诸多领域中已经得到了广泛的应用。对近场天线的应用及设计方法进行深入研究，结合天线近场耦合原理和微带天线谐振腔模型法，提出了一种近场天线的优化设计方法，还将天线应用到电信机柜管理系统中，利用HFSS对设计出的天线进行仿真，并加以测试验证。制作出的天线经过测试，在电信机柜环境下的回波损耗在频带918～926MHz中小于-10dB，并且谐振于922MHz。单根近场天线的近场场强能够覆盖电信机柜管理平面内的500mm×300mm的区域，并据此确定出覆盖整个电信机柜平面的天线系统的设计方案。
Radio frequency identification （RFID） system has been applied to many domains ： traffic, logistics freight, industrial production, equipment monitoring and service industry, etc.. This paper deeply studies the application and design method of near field antenna, puts forward an optimization design method of near field antenna,and applies the antenna to telecom cabinet management system combining antenna near field coupling principle and microstrip antenna resonator model method, u- ses HFSS to simulate the designed antenna and performs test ＆validation. For the made antenna, the echo loss is less than --10 dB in the frequency band 918～926 MHz in telecom cabinet environ- ment,resonates at 922 MHz. According to that near field strength of single near field antenna can cover 500 min× 300 mm in telecom cabinet management plane,the design scheme of antenna system covering total telecom cabinet plane is determined.
