The paper describes how chipless RFID tags in motion can be read at higher distances than what is currently done without taking into account displacement. The movement results in the appearance of a tag backscattered field containing frequencies different from those emitted by the reader according to the Doppler effect. The use of these frequencies not generated by the reader considerably increases the reading distance of the tag, especially in a real environment. This paper is focused on a rotational movement of the tag. The proof of concept is carried out on elementary chipless tags which will be read up to 10 m.
