Transponder incorporated into an electronic device

Abstract

An electronic device. The device comprises a metalization layer and an integrated circuit chip incorporated into the device wherein the integrated circuit chip is capacitively coupled to the metalization layer. The device comprises a first substrate having the metalization layer formed on the substrate, a cap layer covering at least the entire metalization layer and at least a portion of the first substrate not covered by the metalization layer. The integrated circuit chip is coupled to the first substrate, and is placed in proximity and in non-physical contact with the metalization layer. A conductive layer is attached to the integrated circuit chip. The conductive layer has at least a portion placed in a non-physical contact with the metalization layer. The integrated circuit chip is capacitively coupled to the metalization layer through the conductive layer and the metalization layer.
