In the production radio frequency (RF) sensable objects, it is possible to produce a package, envelope (10), or like container which has enhanced read distance, producable by a simple method. Large areas are printed on the envelope or package in conductive ink (12, 14) which are separated by a non-conductive portion (15) of the package or envelope and function as an RF antenna. Then by placing an otherwise conventional label (17) with an RFID chip (19) associated with it so that it bridges the conductive ink portions of the RF antenna, a much easier to sense or read product is produced. The conductive ink can be applied in a pattern, logo, and letters or character indicia. The label may have conductive pressure sensitive adhesive on one face, which actually connects the antenna sections to the RFID chip to form the operable structure that can be sensed by an RF receiver at a distance of three meters or more. |
