Abstract

Described are RFID structures and methods for forming RFID structures. An RFID structure includes an antenna substrate and a loop antenna assembly positioned on the antenna substrate. The loop antenna assembly includes at least two contact pads and a plurality of antenna loop windings having an average spacing between adjacent antenna loop windings of the plurality of loop windings. The plurality of antenna loop windings define one or more gap regions that separate adjacent or adjoining antenna segments of the plurality of antenna loop windings by at least twice the average spacing.
