新型圆极化微带天线在物流仓储中的研究与设计
Research and Design of New Circularly Polarized Microstrip Antenna for Logistics Warehousing
摘要
Abstract
The reader antenna plays a vital role in the communication of RFID system,antenna design and manufacturing technology directly affect the function of the RFID system.In order to achieve flexibility,efficiency and accuracy of information gathering process in RFID system,this paper presents a new type of circular polarization microstrip antenna using Rogers TMM4 as the dielectric layer.A coaxial probe radiation patch is used to feed the rectangular radiating patches in the two long sides which are cut by two equilateral triangles.The cut microstrip antenna works in a circular polarization,and can increase the operating bandwidth of microstrip antenna,reduce the reflection coefficient.Simulation shows that the lowest reflection coefficient of the antenna is-14.426 dB,center frequency is 915 MHz,the reflection coefficient is less than-10 dB,and bandwidth range is 910～ 923 MHz,Its gain is up to 5 dB.关键词
