test chamber can hardly affect the reading range of the RFID tag.
The height of the RFID tag from the ground in the range of 0.7–1.3 m has a great
impact on the property of the RFID tag. Since the conveyor height and antenna height
are fixed, the antenna has a reading range. To test the optimal ground clearance for
