The document (1) has sheets (11, 12, 13) connected with one another, where one of the sheets has a carrier layer (20), an antenna structure (21) for radio frequency communication and an electronic circuit (22) connected to the structure. Another sheet has a carrier layer (30) and electrically conductive layers for forming an inductance-capacitance-resistance (LCR) circuit (3). The structure and the LCR circuit are arranged on the respective carrier layers, such that regions of the sheets overlap when a booklet is closed and the LCR circuit is electromagnetically coupled to the structure. |
