Abstract
An RFID read antenna assembly () for use on a metal substrate () is used to read an RFID tag () carried by an article () positioned relative to the metal substrate. The antenna assembly comprises a high permeability layer () mountable to the metal substrate, an elongate carrier () mounted to the high permeability layer and defining a longitudinal axis (), and at least one antenna coil () carried by the elongate carrier. The at least one antenna coil has a plurality of uniformly spaced transversely arranged portions () defining a sequence of antenna loops () of substantially constant width. The width of each antenna loop is substantially the same as the spacing between adjacent transversely arranged portions.
