Abstract:
An electronic device that includes a metal element arranged to at least partially cover a high impedance region associated with an antenna of the electronic device. The metal element presents a capacitive load to the antenna to mimic or replicate a capacitance placed on the antenna by a conductive element, such as a user's finger, coming in contact or close proximity to the antenna area. The capacitive load applied by the metal element tunes the antenna system for a large capacitance to resist antenna de-tuning and radio link interruption caused by the unintended user contact or near contact with the high impedance region of the antenna.
