An antenna comprises an antenna coil 21 and a planar conductor 2. The antenna coil includes a magnetic-material core 1 and a coil conductor CW. The coil is arranged toward a certain side S of the planar conductor 2. A first conductor part 11 of the coil conductor is situated close to a first main face MS1 of the core, and a second conductor part 12 is close to a second main face MS2 of the core. The two conductor parts are arranged such that they are offset from one another and do not overlap. The second conductor part 12 is arranged further from the center of the planar conductor than is the first conductor part 11. In addition, a coil axis CA of the coil conductor CW is orthogonal to a side S of the planar conductor 2. The antenna is suited to application with a radio frequency identification device (RFID). The antenna can provide for a longer communicable distance. |
