Abstract:
1. An antenna circuit comprising a substrate, an antenna coil on only one side of the substrate, and a low-profile crossover element on said one side of the substrate and which bridges at least one turn of the antenna coil to electrically interconnect an inner end portion and an outer end portion of the antenna coil, the crossover element comprising an electrically insulative layer on or adjacent to said turn of the antenna coil, a first electrically conductive layer above the electrically insulative layer, and a second electrically conductive layer which is disposed directly on the first electrically conductive layer and which is of a different electrically conductive material, the substrate including a body portion and a chip-connecting portion connected on one end to the antenna coil.
