| 发明名称 | Electronic timepiece with internal antenna | ||
| 摘要 | An electronic timepiece has a case of which at least part is made from a conductive material; an annular antenna housed in the case; and a dial disposed inside the antenna. The antenna has an annular dielectric base. The base has a sloped surface that slopes toward the dial and decreases in height to the dial with proximity to the inside. The antenna element is made from a conductive material and is fed by the feed part of the antenna, and is disposed to the sloped surface of the base. | ||
