Abstract: A method for producing at least one transmitting and/or receiving antenna (2) for transmitting and/or receiving electromagnetic waves. Electrically conductive threads are worked into a textile substrate material (1) as transmitting and/or receiving antennas (2) by means of a tricot machine or Raschel machine. The invention further relates to a corresponding transmitting and/or receiving antenna (2).

Abstract: An RFID system with an RFID chip and a transmitting and/or receiving antenna that are applied onto a substrate material for sending and/or receiving electromagnetic waves. The transmitting and/or receiving antenna is formed by only a single electrically conductive thread that forms a linear, non-intersecting structure. A segment of the electrically conductive thread loops around the RFID chip without touching it across an angle of at least 180°, by which a capacitive coupling is effected between the RFID chip and the transmitting and/or receiving antenna. The invention further relates to a method for producing an RFID system.

Abstract: The security packaging device according to the invention consists of a known cut-resistant textile structure having integrated conductive thread layers which, in the event of mechanical loading, trigger an alarm signal. When cut-resistant knitted spacer fabrics are used, the inner surfaces of the top side and the entire underside or the inner surfaces thereof are conductive. Additional weft insertion threads, which are parallel to the spacer threads, are arranged as spacers between the top side and underside, in order to prevent any unintentional contact if pressure is applied.
