16 Bit retransmission based chipless RFID tag

Abstract

A 16-bit Chipless RFID tags have been proposed in this report. The design will be fabricated on a Rogers RT 5880 board with a dielectric constant of 2.2 and a loss tangent of 0.0009. The tag is based on the concept of re-transmission and therefore require an external set of monopole patch antennas as part of the system. The design employ the use of L resonators with various,de ned lengths which in turn resonate at di erent frequencies. The presence or absence of a resonator at a particular frequency is encoded as a 1 or 0. These tags are intended to solve some of the issues that are faced by the conventional passive RFID and the main focus has been replacement of the barcode which is a smart retail use case.
