<P>PROBLEM TO BE SOLVED: To provide an antenna device mounted with an antenna integrated magnetic sheet which is made thin and lightweight, is inexpensive, and has superior productivity and high performance. <P>SOLUTION: The antenna device 1 of an RFID system communicating data without contacting comprises the magnetic sheet 2, a base material 6 arranged closely to the magnetic sheet 2, an antenna 3 provided in the base material 6, and a matching circuit 4 provided in the base material 6. A chip capacitor constituting the matching circuit 4 is mounted bridging a conductor of the antenna 3 to improve productivity, and further the antenna device is suppressed in cost for the base material 6 and made thin and lightweight. <P>COPYRIGHT: (C)2007,JPO&INPIT |
