Design of RFID Reader Using Multi-Antenna with Difference Spatial Location

Radio-frequency identification (RFID) is contactless automatic identification technology which is rapidly development lately. In order to intelligent management systems using RFID technology have the ability of location identification, design scheme of RFID reader using multi-antenna of difference spatial location is presented in this paper. It is a separated setting of reader and multi detecting antennas. The receiving information from tags contains antenna code and data in tag's IC. Hence the reader can indicate the tags position through different antenna code. The managing system of intelligent medicine-chest based RFID technology with reader presented in this paper not only can provide location identification, but also can reduce system cost. It will have wide application in future.
