In this paper, a novel design method for chipless RFID tags in frequency domain has been introduced. The tags are designed based on letters and symbols, and printed on the cheap substrates, such as plastic and paper. These tags are part of a bigger system which uses Artificial Intelligence for decoding. This paper demonstrates the way to adjust the dimensions of the letters so that desired backscatter frequency response can be achieved. This work makes the implementation of cheap and flexible tags easier for the IoT application in the mm-wave band.
