<P>PROBLEM TO BE SOLVED: To provide an antenna apparatus which is capable of stable communication even when the size of the antenna apparatus is relatively reduced as compared with that of an apparatus on the other end of the line, and even when two communicating antennas are disposed in close proximity to each other on the same axis. <P>SOLUTION: The antenna apparatus includes a conductor layer 2 having a conductor aperture CA and a slit portion SL linking between the conductor aperture CA and an outer edge. When a coil conductor 31 is planarly viewed, an aperture CW of the coil conductor 31 overlaps the aperture CA of the conductor layer 2. The area of the conductor layer 2 is larger than the area of a region in which the coil conductor 31 is formed. A magnetic sheet 39 is provided so as to cover the aperture CW of the coil conductor 31 and the aperture CA of the conductor layer 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
