一种面向多频段的小型化RFID读写天线设计
Design of miniaturized RFID read-write antenna for multi-band
摘要
Abstract
With the development of high-speed communication and various intelligent ubiquitous in Internet of Things,radio frequency identification(RFID)has been widely used as one of the core key technologies.In allusion to the current engineering demand for multi-band miniaturized RFID antennas,a four fold-band ultra-high frequency antenna with improved microstrip patch configuration is designed for the RFID multi-band communication system.Based on a microstrip rectangular patch antenna,this antenna can realize communication in four operating frequency bands by introducing the"mountain"shaped slot antenna and the dual-ring split ring resonator(SRR)structure.The operating frequencies are 0.9 GHz,1.2 GHz,2.22 GHz,and 2.56 GHz,with relative bandwidths of 7.9%,8.2%,7.3%,and 5.9%,respectively.In comparison with existing RFID antenna design schemes,the designed antenna has more operating frequency points and more ideal relative bandwidth.关键词
