Abstract
An RFID system for tracking tagged items comprises an RFID reader and an RFID antenna coil arrangement in communication with the RFID reader. Each item has an RFID tag with a tag antenna coil and each item is positioned in a fixed location. The RFID antenna coil arrangement comprises a plurality of conductively connected antenna coils, wherein each antenna coil is oriented in a plane perpendicular to an orientation of the RFID tag antenna coil associated with the respective tagged item. Each antenna coil is also positioned to be aligned with the fixed location of a respective tagged item, so that the RFID tag antenna coil couples with a fringing flux produced by the antenna coil.
