Abstract:
A method for fabricating a radio frequency identification tag device, the method comprising:providing a substrate comprising first and second major surfaces, wherein a first portion of the substrate comprises a connector tab; providing a circuit pattern on a first major surface of a substrate, the circuit pattern comprising: an antenna pattern comprising first and second ends; a first connection pad and a second connection pad, wherein the first connection pad is located on the first major surface of the substrate within the connector tab; a common capacitor plate in electrical communication with the antenna pattern; and a plurality of tuning capacitor plates, each of the tuning capacitor plates in electrical communication with the antenna pattern through a tuning capacitor plate connection; folding the connector tab along a connector tab fold line such that the first major surface of the substrate within the connector tab faces the first major surface of the substrate outside of the connector tab; wherein the plurality of tuning capacitor plates are located on the connector tab or the common capacitor plate is located on the connector tab such that the plurality of tuning capacitor plates and the common capacitor plate form a capacitor after the folding; and wherein the first connection pad faces the second connection pad after the folding.
