Electronic timepiece with internal antenna |
| 摘要 |
A small electronic timepiece with an internal antenna can maintain high GPS reception performance and affords greater freedom developing different models. The timepiece has an outside case; a time display unit that displays time and that is disposed inside the outside case; a drive unit that drives the time display unit and that is disposed inside the outside case; and an antenna that is disposed around the drive unit inside the outside case, and includes an C-shaped or annular antenna element in contact with the dielectric base. The timepiece may include power supply nodes from which power is supplied to the antenna, one such node being disposed at one end of the C-shaped antenna element and the other being disposed at the other end of the C-shaped antenna element. The annular antenna element may be embedded in the dielectric base. |
