1. An electronic device having a periphery, comprising:

  • radio-frequency transceiver circuitry;

    an antenna having an antenna feed and ground plane structures;

    a transmission line path coupled between the radio-frequency transceiver circuitry and the antenna feed;

    peripheral conductive housing structures that run along the periphery and surround the ground plane structures, wherein the peripheral conductive housing structures include a portion that forms at least part of the antenna;

    storage and processing circuitry configured to generate a control signal; and

    an adjustable electrical component coupled to the peripheral conductive housing structures, wherein the adjustable electrical component has a control input that receives the control signal and the adjustable electrical component is configured to adjust a frequency response of the antenna based on the control signal.
