Abstract: The present disclosure pertains to a transponder device (10) having an antenna arrangement and a chip (13) disposed on an antenna substrate (11), wherein the antenna arrangement comprises at least a first antenna unit formed as a loop antenna (16) that is connected electrically conductively to contact surfaces (14, 15) of the chip via conductor ends of an antenna conductor (17) that is used for the formation of the loop antenna, and wherein the antenna arrangement besides the first antenna unit comprises at least one further antenna unit formed as a dipole antenna (19).

Abstract: An RFID Tag (10, 25, 36, 37) includes a transponder unit (29) that has at least a chip (21) and an antenna means (17) and further including a molded body (15, 27, 38, 44) for accommodating the transponder unit, the molded body being made from an elastic and deformable material.

Abstract: The present disclosure generally pertains to a transponder device (10) comprising a transponder unit (37), which is arranged in a housing (13) and has an antenna device (38) and a chip (39), the housing forming a receiving space between a transparent front wall (15) and a housing rear wall (16) having arranged therein an optically readable information carrier (34), the housing rear wall having a fastening edge (22) defining a fastening plane (21) of the housing.

Abstract: A method and apparatus of forming a battery enabled flexible circuit. The invention includes forming a first insulating layer and positioning a battery on the first insulating layer, the battery having at least a first and a second terminal. A second insulating layer is then formed on the first insulating layer and the battery. The second insulating layer has vias that are in electrical contact with at least one of the first and the second terminals.
