CHAPTER 12SIGNAL PROCESSING FOR MIMO-BASED CHIPLESS RFID SYSTEMS

12.1 INTRODUCTION

In Chapter 8, several chipless tags have been studied and it is concluded that multiresonator-based chipless tags will be further investigated in order to incorporate them with the proposed MIMO-based chipless RFID system. The main reason is that the multiresonator tags are reported as one of the chipless tag types with the largest data capacity. Also, Monash Microwave, Antennas, RFID and Sensors Laboratory (MMARS) has all the required equipment and facilities for tag fabrication and testing.

An overview of the proposed MIMO-based chipless RFID system is illustrated in Figure 12.1. The chipless tag used in the proposed system is multiresonator based, where each resonator acts as a bandstop filter introducing a frequency signature to the tag.

The tag considered earlier has one receiving antenna (Rx) and two transmitting antennas (c12-math-0001 and c12-math-0002) cross-polarized with Rx as shown in Figure 12.1. The RFID reader has one transmitting antenna (Tx) that is cross-polarized with its two receiving antennas ( and ), hence minimizing the coupling between transmitting and ...
