1. An electronic device comprising:

  • a housing having a conductive member that runs around a periphery of the housing;

    an inverted-F antenna that is formed from an antenna ground and a portion of the conductive member, wherein the inverted-F antenna is configured to operate in a low-band frequency range centered at a first frequency and a high-band frequency range centered at a second frequency that is greater than the first frequency; and

    a switchable inductor coupled between the antenna ground and the portion of the peripheral conductive member, wherein the switchable inductor is configured to center the high-band frequency range at a third frequency that is greater than the first and second frequencies while the inverted-F antenna maintains operation in the low-band frequency range centered at the first frequency.
