Abstract
The present invention provides radio frequency resonant tags and methods of manufacturing these tags for use in detection of theft of article for sale. In these tags, the radio frequency is transmitted through a resonance circuit without the need for direct connection of a conducting pattern or conducting patterns, but rather via a dielectric film which is adjacent to the conducting pattern or separates the conducting patterns.
