A method for manufacturing wireless communication devices for use in tracking or identifying other items comprises a number of cutting techniques that allow the size of the antenna for the wireless communication device. Further, the chip for the wireless communication device is nested so as to be flush with the surface of the substrate of the wireless communication device. Rollers cut the tabs that form the antenna elements. In a first embodiment, a plurality of rollers are used, each one effecting a different cut whose position may be phased so as to shorten or lengthen the antenna element. In a second embodiment, the rollers are independently positionable to shorten or lengthen the antenna element.
