英文摘要： RFID based on the mobile phone platform is a new technology, combining the RFID reader with mobile phone which is used as a mobile communication terminal, and it can help us obtain information rapidly through the mobile communication network platform. It brings a new development direction in the field of electronic information which will radically change the way of information obtaining. This issue conduct study thoroughly on several critical technology of RFID which is based on the mobile phone platform. According to the theoretical basis of the electromagnetic field distribution and transmission characteristics of the information obtaining process, the design method of antenna miniaturization which use EBG circuit as a reflector has been studied in order to improve the directivity of the RFID antenna and the isolation between RFID antenna and mobile phone antennas. Microwave matching circuit made by the method of LTCC craft has been adopted in order to realize the miniaturization of embedded RF modules. Express anti-collision algorithm and other critical theory and technology has been studied to adapt to the application characteristics of RFID which is base on the mobile phone platform in the case of multiple reader, providing theoretical basis for RFID design scheme and application standards based on the mobi
