Analogue watch comprising a micro-transponder associated with an antenna-resonator intended for increasing the reading distance of said micro-transponder using an RFID reader

摘要

The wristwatch (4) has a micro-transponder (1) e.g. ROM memory chip, including an antenna i.e. coil-on-chip type antenna, integrated to an integrated circuit chip. The micro-transponder is connected to a passive antenna i.e. antenna-resonator (2), of large dimensions without electrical connections, by using a magnetic/electromagnetic coupling. The antenna-resonator is situated near the micro-transponder and formed by printing an ink formed of transparent electrically conducting polymer compound, on an inner surface of a watch glass (3) i.e. support.
