In our R&D study, we found that antenna patterns printed on the film by thermal transfer ribbon bear the basic frequency characteristics as film antenna, which are used for inlet of IC tags, car navigation systems, etc. We are convinced that the manufacturing of film antennas can be more simple process and lower cost by using thermal transfer printing technology.
