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： In antenna device, a coil conductor of an antenna coil module and a conductor layer at least partially overlap. A current flows in the conductor layer to block a magnetic field generated by a current flowing in the coil conductor. A current flows along the periphery of a slit and around the periphery of the conductor layer due to a cut-edge effect. Since magnetic flux does not pass through the conductor layer, magnetic flux attempts to bypass the conductor layer along a path in which the conductor opening of the conductor layer is on the inside and the outer edge of the conductor layer is on the outside. As a result, the magnetic flux generates large loops that link the inside and the outside of a coil conductor of an antenna on a reader/writer side to couple an antenna device and the antenna on the reader/writer side.

摘要： An antenna includes two feeding points, and includes a loop-shaped loop electrode and an auxiliary electrode electrically connected to the loop electrode and located at a position along the outer circumference of the loop electrode. The first end portion of the auxiliary electrode is electrically connected to the vicinity of one feeding point of the loop electrode. The second end portion of the auxiliary electrode is open. A resonant circuit is defined by the auxiliary electrode and the loop electrode to enhance the impedance of the antenna, compared with a case in which the antenna is configured using the simple loop electrode, and it is easy to achieve impedance matching with the wireless IC.

摘要： An antenna includes first and second radiation portions including one lead wire that is folded back into a loop shape to define a folded-back portion and that includes a first power feed portion at a first end and a second power feed portion at a second end. The lead wire portion extending toward the folded-back portion and the lead wire portion extending through the folded-back portion are close enough to each other near each of the first and second power feed portions in the first and second radiation portions, respectively, to be electromagnetically coupled to each other. The power feed portions of the antenna are coupled to a wireless IC chip. The power feed portions may be coupled to a feed circuit in a feed circuit board coupled to a wireless IC.
