摘要： An electronic watch with a built in antenna includes a watch case including a case body configured of a conductive material, a bezel configured of a conductive material and provided on a watch front surface side of the case body, and a cover glass attached to the bezel. The electronic watch includes a dial disposed inside the watch case, a dial ring disposed around the dial, and an antenna disposed inside the watch case. At least a portion of the antenna is disposed outside an outer circumference of the dial in plan view as seen from a direction orthogonal to a front surface of the dial. At least one of the dial, the dial ring, and the cover glass is a dielectric disposed to be closer to the watch front surface side than to the antenna and disposed within a predetermined distance from the antenna, the distance being set in accordance with a wavelength of radio waves received by the antenna.

摘要： Provided is an electronic timepiece enabling reducing the size of an electronic timepiece. The electronic timepiece has an antenna having a first conductor element connected to a feed, a second conductor element superimposed with the first conductor element in plan view, and a dielectric disposed between the first conductor element and second conductor element, and the antenna holds a specific timepiece part. The specific timepiece part is preferably a dial, solar panel, or circuit board. The antenna also preferably has a shorting element that shorts the first conductor element and second conductor element.

摘要： An electronic timepiece has an antenna having a first conductor element connected to a feed, a second conductor element superimposed with the first conductor element in plan view, and a shorting element shorting the first and second conductor elements; a solar panel; a circuit board electrically connected to the feed; a connector electrically connecting the solar panel and the circuit board; and a case having a side wall and housing the antenna, solar panel, circuit board, feed, and connector. A through-hole through which a pivot passes is disposed to the antenna at a position different from the shorting element. The connector is disposed in plan view to a third area excluding from a first area surrounded by the side wall a second area defined by a line indicating a position one-third the distance from the center of the first or second conductor element to an outside circumference.

摘要： An inverted-F antenna is included in an electronic timepiece without increasing the thickness of the electronic timepiece. In an electronic timepiece having a dial, a plastic calendar plate disposed on the back cover side of the dial, and a main plate disposed on the back cover side of the calendar plate, a first conductor element, second conductor element, and a shorting element shorting the first conductor element and second conductor element are formed in unison with the calendar plate, enabling the calendar plate to function as an inverted-F antenna. The first conductor element is disposed on the dial side surface of the calendar plate, and superimposed with the dial in a plan view. The second conductor element is disposed on the main plate side of the calendar plate, and superimposed in the plan view with the first conductor element. The shorting element is disposed to the side of the calendar plate.
