1. An electronic device, comprising:

  • a housing having peripheral conductive structures;

    first and second dielectric gaps formed on opposing sides of the electronic device that divide the peripheral conductive housing structures;

    an antenna resonating element formed from a segment of the peripheral conductive structures located between the first and second dielectric gaps;

    an antenna ground;

    an antenna feed having a first antenna feed terminal coupled to the segment and a second antenna feed terminal coupled to the antenna ground;

    a parasitic antenna resonating element formed between the segment of the peripheral conductive structures and the antenna ground; and

    an adjustable component that is coupled to the segment and the antenna ground and that overlaps the parasitic antenna resonating element.
