An electromechanical timepiece module (1) has a main plate (10) with an actuator module (40) driving at least one mobile part (30) by a gear train (42). The mobile part (30) displays a time or non-time function. A wireless communication module (2) is configured for transmitting and/or receiving a wireless signal. And a control unit (6) is configured for controlling the actuator module (40) depending on a received wireless signal. The mobile part (30) and the gearing (42) are made of an electrically conductive material and are in electrical contact with each other but electrically isolated from the remainder of the timepiece module (1). The mobile part (30) is electrically connected to the communication module (2) so as to act as an antenna for the transmission and/or reception of the wireless signal and to transmit the wireless signal between the mobile part (30) and the wireless communication module (2).

A coupled antenna apparatus particularly well adapted for small form factor, metal encased applications that utilize satellite wireless links, e.g. GPS. Certain examples use electromagnetic feeding that includes one or more separate feed elements that are not galvanically connected to a radiator element of the antenna. Additionally, one radiator element of the antenna can be located on an outermost surface of a bezel of an electronic device, for example a wrist-wearable device. A resonating circuit is housed within an electronic device and electrically coupled to such an outer radiator element.

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.

An antenna is provided for a wearable personal computing device, such as a smartwatch. The antenna integrates with other components of the wearable device, such as a second antenna. For example, the first antenna may be a coupled loop antenna in proximity to a second antenna that may be a monopole antenna, without causing interference between the two antennas. In one example, the first antenna shares a common ground with the second antenna.
