Abstract:
1. A method for producing an antenna for a transponder on a substrate, which also includes a chip or a chip module, the method comprising a first work process comprising the steps of: a) producing electrically conducting connecting surfaces for connecting an antenna conductor and/or a chip or a chip module, wherein a plurality of first connecting surfaces are produced on a first substrate surface and a plurality of second connecting surfaces are produced on at least one second substrate surface different from the first substrate surface, b) producing a plurality of electrically conducting connections between each of two or more of the first and second connecting surfaces arranged on different ones of the first and second substrate surfaces, the method further comprising a second work process following the first work process, the second work process comprising the steps of: c) producing a first antenna section on the first substrate surface, d) producing at least one second antenna section on the at least one second substrate surface, e) connecting the first antenna section with at least two first connecting surfaces arranged on the first substrate surface, and f) connecting the second antenna section with at least two second connecting surfaces arranged on the at least one second substrate surface, and g) forming a complete antenna by connecting the first and second antenna sections by way of the plurality of electrically conducting connections, wherein the complete antenna is arranged in at least two non-identical planes and the first and second connecting surfaces are configured for connection to the chip or chip module.
