摘要： An antenna device includes a base including a planar conductor disposed thereon, and a coil antenna. The coil antenna includes a coil conductor wound around a magnetic core. The coil antenna is arranged such that a coil opening of the coil conductor is closed to an edge of the planar conductor. A current passing through the coil conductor induces a current in the planar conductor. Thus, a first magnetic flux occurs in the coil antenna, and a second magnetic flux occurs in the planar conductor. Therefore, a third magnetic flux occurs in an area of the planar conductor. Accordingly, the antenna device achieves a small footprint, a small-sized communication terminal apparatus and a desired communication distance.

摘要： An antenna includes a flexible sheet that includes a first main surface including a first coil electrode located thereon and a second main surface including a second coil electrode located thereon. The first and second coil electrodes are wound in opposite directions when viewed from different directions. A first end of the first coil electrode faces a first end of the second coil electrode through the flexible sheet. Similarly, a second end of the first coil electrode faces a second end of the second coil electrode through the flexible sheet. The first and second coil electrodes define an inductor, the first ends of the first and second coil electrodes define a capacitor, and the second ends of the first and second coil electrodes define a capacitor whereby a resonant antenna is provided.
