CHAPTER 8INTRODUCTION

Item tagging and monitoring have become significant than ever before, due to the recent emergence of new technologies and their mass-market penetration. Particularly in mass production sites, automated item tagging can increase the productivity and efficiency, which in turn will increase the company revenue. Optical barcode technology is dominant in the item tagging market at present due to its relatively low implementation cost. However, there are a number of limitations such as low reading range, line of sight (LOS) requirement for reading, and its inability to identify multiple items simultaneously. All these challenges suggest barcodes is not a feasible solution in automating item tagging. Radio frequency identification (RFID) shades the light to overcome these limitations toward automating the process, however with high-priced tags. The focus of this research is to produce tags that are comparable to optical barcodes in price, while providing the functionality. This is achieved by removing the microchip and using special techniques hence, called chipless RFID tags. This section of the book presents a few advanced tag detection techniques and a high-data-capacity chipless tag using likelihood-based detection techniques and multiple input multiple output (MIMO) tag design.
