摘要
射频识别技术(RFID)是一种自动身份识别技术,其出现和普及极大地方便了人们的工作和生活。RFID系统天线设计涉及电磁场电磁波理论,难度最大,也是最重要环节,故工程实践中天线设计都需经过计算机辅助设计软件仿真,再加工成实物。现有RFID天线辅助设计软件功能丰富,但使用繁琐,初学者很难快速掌握。本文探讨一种高频RFID天线计算机辅助设计软件,采用Python语言建模高频RFID线圈与匹配电路,实现高频RFID天线特性仿真,包括高频RFID天线线圈等效电感、电阻和电容仿真计算,以及天线回路频率特性仿真分析。与现有RFID天线辅助设计软件相比,软件提供设计指导,可以帮助初学者快速掌握高频RFID天线设计。
Radio frequency identification(RFID)is an automatic identification technology.Its emergence and popularization greatly facilitate people's work and life.RFID system antenna design involves electromagnetic wave theory,which is the most difficult and important step.Therefore,in engineering practice,antenna design needs to be simulated by computer-aided design(CAD)software and then be processed into real objects.The existing RFID antenna CAD software has rich functions,but the use is cumbersome,so it is difficult for beginners to master quickly.This paper discussed a CAD software of high-frequency RFID antenna,which uses Python language for modelling high-frequency RFID coil and matching circuit to realize the simulation of high-frequency RFID antenna,including the calculation of equivalent inductance,resistance and capacitance of high-frequency RFID antenna coil and the analysis of antenna frequency characteristics.Compared with the existing RFID antenna aided design software,the software provides design guidance to help beginners quickly master the design of high-frequency RFID antenna.
