Document Type and Number:
Japanese Patent JP7070611
Kind Code:
B2
Abstract:
To provide an antenna device that does not deteriorate characteristics of an antenna even if the antenna device is contained in a metal enclosure, and does not increase manufacturing steps while maintaining unity of its design.SOLUTION: An antenna device includes: an antenna part 20 in which a conductor wire 22 is wound around a magnetic substance 21; and a metal enclosure 110 for containing the antenna part 20 therein. On the metal enclosure 110, there is formed a slit 111 (first notch) in an X-axis direction orthogonal to (intersecting with) a Y-axis direction in which the conductor wire 22 is wound around so that a magnetic field generated by the antenna part 20 passes through.SELECTED DRAWING: Figure 5
