Abstract: An ID transmitter for a motor vehicle access system includes a printed circuit board which is enclosed by a plastic housing. An antenna subassembly arranged next to the printed circuit board is connected thereto and includes a carrier film carrying conductor tracks. The components include a power supply cell, an LF 3D coil assembly, and HF transceiver components, an NFC module and at least one controller component. The conductor tracks of the carrier film form an NFC antenna coil which is coupled to the NFC modules via the conductors of the printed circuit board. The carrier film is arranged substantially in a plane parallel to the printed circuit board and protrudes over the edge of the printed circuit board on all sides. The conductor tracks forming the NFC antenna coil are arranged primarily in the edge region of the carrier film protruding over the edge of the printed circuit board.
