A wrist phone with a single button includes a molded-plastic wristband and a wristband cap. A wireless transceiver module is mounted on a printed circuit board and is contained in a component cavity between the wristband and the wristband cap. A foil antenna is attached directly to the printed circuit board and extends between an outer layer and a wrist-facing layer of a flexible strap portion of the wristband. A microphone is located between the layers of the opposite flexible strap portion of the wristband at least two centimeters away from the wireless transceiver module. The single button is formed using the interleaved fingers of a landing pad on a surface beneath the inner surface of the wristband. The inner surface of the wristband is covered by a layer of conductive material that makes an electrical connection between the interleaved fingers when the outer surface of the wristband is pressed.
