<P>PROBLEM TO BE SOLVED: To provide an RFID antenna which obtains stable communication characteristics at low cost, and to provide an electronic apparatus including the RFID antenna and a chip ferrite component used for the RFID antenna. <P>SOLUTION: Chip ferrite 34 is surface-mounted on an antenna pattern 32 of an antenna substrate 31. This structure improves the accuracy of the mounting position, suppresses variations of antenna characteristics, and increases the productivity. Further, a solder fillet is formed at a soldered portion between an electrode of each chip ferrite 34 and the antenna pattern to increase a cross section of the antenna pattern 32 substantially. <P>COPYRIGHT: (C)2012,JPO&INPIT |
