Abstract
In accordance with exemplary embodiments of the invention, antenna structures having specified geometries (e.g., serpentine, slot, etc.) are provided for incorporating into fixtures such as shelves. Preferred antenna structures of the invention can be used as tag reader antenna systems in RFID (radio frequency identification) applications and the like. In accordance with an exemplary embodiment, multiple RF (radio frequency) antennae are utilized as part of an intelligent station to track items comprising radio frequency identification (RFID) tags.
