1. An electronic device, comprising:

  • a housing having peripheral conductive housing structures that run around at least first, second, third, and fourth edges of the housing, wherein the first edge opposes the third edge and the second edge opposes the fourth edge;

    an antenna ground, wherein the antenna ground is formed at least partly from conductive portions of the housing;

    a first dielectric-filled gap in the peripheral conductive housing structures along the first edge of the housing;

    a second dielectric-filled gap in the peripheral conductive housing structure along the third edge of the housing; and

    an inverted-F antenna that includes an antenna resonating element arm formed from a segment of the peripheral conductive housing structures that extends from the first dielectric-filled gap to the second dielectric-filled gap, the antenna ground, a conductive structure coupled between the antenna resonating element arm and the antenna ground, and an antenna feed having a positive feed terminal coupled to the segment of the peripheral conductive housing structures and a ground feed terminal coupled to the antenna ground.
