摘要: A novel radio frequency transponder (tag) with a minimum of components and connects is thin flexible because these can be unsupported by substrate layer. This accomplished using conducting leadframe structure not only as connection medium but also circuit element, i.e., the antenna. In various preferred embodiments, mechanically positioned fixably attached to chip so that (antenna) self supporting. protective coating added where chip. Further surrounding envelops entire antenna, chip, and, if provided, coating.
