Development of a movable RFID antenna for recognizing contents of containers in living space (A prototype of the movable antenna realizing robust RFID tag reading regardless of container contents' postures)

摘要

This paper describes development of a movable RFID antenna for reading RFID tags which are attached to contents of containers in living space. Regardless of container contents postures, the equipment realizes robust RFID tags' reading by utilizing its swiveling and vertical motions of RFID antenna. The motions are actualized by two rotating mechanisms and one translating mechanism. By experiments, it is confirmed that the method to read RFID tags with movable RFID antenna is applicable to robust reading. The antenna moving speed and hold time has much relation to recognition performance. It's also showed that small quantities of metal material can make the body structure simple with no effect for reading performance.
