Abstract
An improved RFID tag reader is provided. More specifically, an RFID tag reader is provided that includes a plurality of antenna panels arranged to form a sensing volume in which RFID tags are read. Additionally, the RFID tag reader includes a novel switching mechanism that activates the antenna panels in sequence while minimizing cross coupling between the antenna panels. Furthermore, a novel antenna geometry also reduces antenna cross coupling.
