Radio-frequency identification (RFID) tags are widely used in the food supply chain where they can be used to hold identification data of tagged objects. They can also be used to provide information related to the quality and safety of the tagged object. This can be achieved by analyzing the RF signals emitted by the tag which couples with the tagged objects, and hence can be used to acquire useful information related to the safety and quality of that object. This paper investigates the correlation between the radiated signals from the tags and the quality characteristics of the tagged objects. It focuses on analyzing the mutual coupling between the tags in an array, in particular, of orthogonal polarization configuration, which shows that more information can be extracted by an array of tags compared to the use of a single RFID tag emitter.
