In the production radio frequency (RF) sensable objects, it is possible to produce a package, envelope, 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 which are separated by a non-conductive portion of the package or envelope and function as an RF antenna. Then by placing an otherwise conventional label with an RFID chip 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.

[ What is claimed is:] [1.]1. A container comprising:at least one container wall having a surface area;a first area of conductive ink at least in part disposed on said container wall and spaced from a second area of conductive ink, said first and second areas of conductive ink separated by substantially electrically non-conductive material, said first and second areas of conductive ink comprising at least part of an RF antenna;a label having a first face, and a second face;said second face having adhesive over at least a portion thereof, capable of attaching said label to said container wall;said label having an RFID chip mounted thereon; andelectrically conductive material associated with said label second face and positioned to connect said first and second areas of conductive ink to said RFID chip when said label second face is placed in a position engaging said first and second areas of conductive ink and bridges said area of substantially non-conductive material, so that said container is detectable by an RF receiver.
