The Design and Implementation of Miniaturization Fractal Microstrip Antenna for RFID System

Abstract

RFID技术的飞速发展对RFID天线提出了更高的要求,分形天线技术在RFID系统中得到了越来越多的应用。本论文针对目前国内外RFID天线研究中存在的问题,以π型分形折叠结构为核心,设计了多款各具特色的高性能RFID天线,基于矩量法进行了仿真分析,制作并测试了天线样品,分析比较了仿真结果与实测结果,尝试使用了多种改进方法提高天线的性能。 论文工作主要包括三个方面: 1.π型分形折叠偶极子天线的设计与分析。将π型分形折叠结构、偶极子天线和镜像补偿结构相结合,设计了一款带镜像补偿结构的π型分形折叠偶极子天线,用矩量法对所设计的天线进行仿真分析,详细研究了天线各参数变化对天线性能的影响,指出实际制...The rapid development of RFID technology has higher demands for RFID antenna, and fractal antenna technology has been more and more applied in RFID systems. In this thesis, against the primary problems in RFID antenna researches at home and abroad, a variety of novel and distinctive fractal RFID antennae with high performance were designed by using a π-fractal folding structure as the core.
