Abstract: A wearable device and method for operating the same are provided. The wearable device includes an antenna element, a first matching circuit, a second matching circuit, and a switch element. The first matching circuit has a first impedance value. The second matching circuit has a second impedance value different from the first impedance value. The switch element is configured to determine whether the antenna element is electrically connected with the first matching circuit or the second matching circuit.
