An apparatus for manufacturing wireless communication devices for use in tracking or identifying other items uses cutting techniques that allow the size of an antenna for the wireless communication device to vary. 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.

1. An apparatus for accepting passage of a conductive material to prepare an antenna for use with a wireless communication device, the apparatus comprising: a first die cut roller configured to make a first cut in the conductive material, the first cut defining a portion of a perimeter of one or more antenna tabs; anda second die cut roller configured to make a second cut in the conductive material, the second cut defining a portion of the perimeter of the one or more antenna tabs, wherein the second cut overlaps the first cut to cut the perimeter of the one or more antenna tabs;wherein the overlap of the cuts made by the first die cut roller and the second die cut roller is adjustable to vary the size of the perimeter of the one or more antenna tabs cut by the die cut rollers. 2. The apparatus of claim 1, wherein the first die cut roller and the second die cut roller are respectively configured to make the first and second cuts in a conductive material that is a copper foil. 3. The apparatus of claim 1, wherein the first die cut roller and the second die cut roller are respectively configured to make the first and second cuts in a conductive material that is an aluminum foil. 4. The apparatus of claim 1 wherein the conductive material is secured to an adhesive backing, and wherein the first die cut roller and the second die cut roller are positioned such that the die cut rollers are spaced from the adhesive backing by the conductive material. 5. The apparatus of claim 4, further comprising a waste roller configured to remove conductive material from outside the perimeter of the one or more antenna tabs and from the adhesive backing. 6. The apparatus of claim 1, further comprising a radiator configured to measure an electrical characteristic of a substrate, wherein the overlap of the cuts made by the first die cut roller and the second die cut roller is adjustable based on the measured electrical characteristic of the substrate. 7. The apparatus of claim 1, further comprising a low signal level, low-frequency radiator configured to assess an electrical characteristic of the one or more antenna tabs, wherein the overlap of the cuts made by the first die cut roller and the second die cut roller is adjustable to provide one or more antenna tabs having a selected optimum read range at a desired operating frequency based on the assessed electrical characteristic of the one or more antenna tabs. 8. The apparatus of claim 1, further comprising a heater configured to heat pins of a wireless communication chip to he coupled to the one or more antenna tabs. 9. The apparatus of claim 8, further comprising a pressure roller configured to mate the pins of the wireless communication chip with fingers on the one or more antenna tabs and with a substrate so that the fingers on the one or more antenna tabs wrap around the pins. 10. The apparatus of claim 1, further comprising a welder configured to weld pins of a wireless communication chip to the one or more antenna tabs. 11. The apparatus of claim 10, wherein the welder is further configured to weld the pins of the wireless communication chip with a low-voltage, high-current electrical pulse. 12. The apparatus of claim 11, wherein the welder is further configured to pass the low-voltage, high-current electrical pulse through the pins of the wireless communication chip. 13. The apparatus of claim 1, wherein the overlap of the cuts made by the first die cut roller and the second die cut roller is adjustable based on a desired capacitance of the one or more antenna tabs. 14. The apparatus of claim 13, wherein the relative phases of the first die cut roller and the second die cut roller are adjustable based on the desired capacitance of the one or more antenna tabs. 15. An apparatus for preparing an antenna for use with a wireless communication device, the apparatus comprising: means for making a first cut in a conductive material passed through the apparatus, the first cut defining a portion of a perimeter of one or more antenna tabs; andmeans for making a second cut in the conductive material, the second cut defining a portion of the perimeter of the one or more antenna tabs, wherein the second cut overlaps the first cut to form the one or more antenna tabs;wherein the means for making the first cut and the means for making the second cut are adjustable to vary the overlap of the first cut and the second cut, thereby varying a size of the perimeter of the one or more antenna tabs. 16. The apparatus of claim 15, wherein the apparatus further comprises means for removing conductive material from outside the perimeter of the one or more antenna tabs and from an adhesive backing. 17. The apparatus of claim 15, further comprising means for measuring an electrical characteristic of a substrate, wherein the overlap of the first cut and the second cut is adjustable based on the electrical characteristic of the substrate. 18. The apparatus of claim 15, further comprising means for heating pins of a wireless communication chip to be coupled to the one or more antenna tabs. 19. The apparatus of claim 18, further comprising means for mating the heated pins of the wireless communication chip with fingers on the one or more antenna tabs and with a substrate so that the fingers on the one or more antenna tabs wrap around the pins. 20. The apparatus of claim 15, further comprising means for welding pins of a wireless communication chip to the one or more antenna tabs.
