The PET film with the silver based UHF antenna pattern and adhesive layer were cut into strips and applied to a 2.8mm acrylic substrate using an 80 Durometer rubber wheel hot stamping press with a roller temperature of 195°C (383°F) and a contact time of 2 seconds at a pressure of 60 psi. The PET film was then removed from the substrate. The resistance of the antennas transferred onto the acrylic substrates were measured by placing two Fluke 189 Multimeter probes across the UHF ring loop on the previously marked points. The resistance of two sample strips, before and after heat stamping to a 2.8mm acrylic substrate, are listed in
