Abstract
Antenna structures and methods of operating the same of a phase-controlled antenna of an electronic device are described. A phase-controlled antenna includes a radio frequency (RF) feed, an antenna structured coupled to the RF feed and including a ground path coupled to a ground node, and a phase-controlling circuit coupled between the ground path and the ground node. The antenna structure is configured to operate at a resonant frequency in a first state, and the phase-controlling circuit is configured to introduce a phase shift in the antenna structure to change the resonant frequency of the antenna structure to a second resonant frequency in a second state.
