A method of tuning an electrically small antenna comprising a radiating element and a support structure comprises applying a force to the support structure to change a shape or a dimension of the radiating element to increase or decrease a frequency at which the electrically small antenna resonates.

An electronic device may include wireless circuitry with a baseband processor, a transceiver, and an antenna. The antenna may be coupled to one or more antenna tuning elements for tuning the antenna over multiple communications (frequency) bands of interest. The baseband processor may be configured to simultaneously broadcast, over a digital interface, an aggregate message that includes control bits for adjusting multiple antenna tuning elements coupled to the digital interface. Adjusting multiple antenna tuning elements by issuing a single broadcast command can help optimize interface efficiency while maintaining compatibility with existing industry standards.
