A method for optimizing the position of passive UHF RFID tags

As a core technology, RFID technology has been more and more widely used with the development of Internet of Things. But in current RFID applications, there is a key problem waiting to be solved. That is, how to make the reader read better? For this problem, we propose a method for optimizing the position of passive UHF RFID tags. Firstly, a relative ideal test environment has been built. And then, for each location of the label attached on the container, change the distance between the container and the antenna along a fixed direction. For each distance, test the read rates. In this way, study the read rate trend of each tag position which is changed with the distance between the antenna and the container. Finally, we come to a general conclusion on how to determine the preferred location of a RFID tag.
