Abstract
An RFID antenna system is described comprising an elongated antenna disposed proximate an interrogation path for interrogating transponders moving along the interrogation path. The antenna is oriented such that the longitudinal axis of the antenna is substantially perpendicular to said interrogation path. The antenna provides an active RF interrogation zone that intersects at least 40% of the horizontal longitudinal plane of the interrogation path.
