ANTENNA DEVICE AND PORTABLE ELECTRONIC DEVICE USING THE SAME |
| 摘要 |
Disclosed herein is antenna device that includes: a first metal member having a first main surface; a second metal member having a second main surface parallel to the first main surface; and an antenna coil having a coil axis perpendicular to the first and second main surfaces, wherein the first metal member constitutes at least a part of a housing of a portable electronic device in which the antenna coil is mounted, at least one slit is formed between the first and second metal members, an inner diameter section of the antenna coil overlaps with the slit in planar view, and the slit has a constant width at least in a region that overlaps with the antenna coil in planar view. |
