In an aspect of the disclosure, a method and an apparatus are provided. The apparatus may be a wearable communication apparatus for wireless communication. The wearable communication apparatus includes communication circuitry, a bezel, and a base. The bezel and the base are conductive. The bezel and the base form at least a part of a housing structure supporting the communication circuitry. The base is electrically connected to the bezel. The communication circuitry is electrically connected to the bezel. The bezel is configured to function as a part of a slot antenna. The communication circuitry is configured to send a first communication signal to the bezel such that the bezel transmits the first communication signal over the air. The bezel is further configured to receive, over the air, a second communication signal and direct the second communication signal to the communication circuitry.

An embodiment of an electronic timepiece includes a cylindrical exterior case, a bezel and a windshield member. In the exterior case, a circuit board is housed. The bezel is formed of a metal material to be ring-shaped, includes an inward flange part that projects from an inner side surface toward a center of the ring-shaped bezel, is arranged on an outer upper side of the exterior case and is electrically connected with the circuit board. The windshield member is formed of a transparent dielectric substance, arranged in the bezel and supported by the inward flange part. The bezel is configured to resonate with a radio wave having a desired frequency by adjustment of at least one of (i) a relative permittivity of the dielectric substance and (ii) an area of an overlap region where the inward flange part and the windshield member overlap each other.
