1. An electronic device, comprising:

  • a housing having peripheral conductive housing structures;

    an antenna resonating element arm formed from a segment of the peripheral conductive housing structures;

    an antenna ground;

    an antenna feed having a positive antenna feed terminal coupled to the antenna resonating element arm and a ground antenna feed terminal coupled to the antenna ground;

    a first adjustable component coupled between the antenna resonating element arm and the antenna ground on a first side of the antenna feed;

    a second adjustable component coupled between the antenna resonating element arm and the antenna ground on a second side of the antenna feed; and

    control circuitry configured to adjust the first and second adjustable components between a first tuning mode in which the first adjustable component forms an open circuit between the antenna resonating element arm and the antenna ground and the second adjustable component electrically couples the antenna resonating element arm to the antenna ground, a second tuning mode in which the second adjustable component forms an open circuit between the antenna resonating element arm and the antenna ground and the first adjustable component electrically couples the antenna resonating element arm to the antenna ground, and a third tuning mode in which both the first and second adjustable components electrically couple the antenna resonating element arm to the antenna ground.
