摘要： A timepiece is provided which ensures connection reliability and improves antenna characteristics. This timepiece includes a wristwatch case which houses a timepiece module, and an antenna which is provided on the upper surface of the wristwatch case in a discontinuous annular shape along the circumferential direction of the wristwatch case and electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case. As a result, since the antenna is electrically connected to the timepiece module in the wristwatch case from outside the wristwatch case, the antenna and the timepiece module are unfailingly and favorably connected to each other. Accordingly, the connection reliability of the antenna is ensured and radio waves are favorably received. In addition, the reception performance and the antenna gain are improved, whereby the antenna characteristics are improved.

摘要： An antenna device includes a parasitic antenna which is a metal member used as a windshield fixing frame of a wristwatch type electronic device, and a feed antenna which is a conductor. The parasitic antenna has an annular shape, and is disposed close to the feed antenna, and is electromagnetically or capacitively coupled with the feed antenna, and acts as a parasitic antenna to which power is fed from the feed antenna in a non-contact manner, and thereby the feed antenna and the parasitic antenna act in cooperation with each other as a circular polarized antenna for receiving radar waves which are circularly polarized waves having a predetermined wavelength.
