摘要:
Antenna structures and methods of operating the same of a dual-feed antenna of an electronic device are described. A dual-feed antenna includes a first antenna element coupled to a controllable circuit that is coupled a first radio frequency (RF) feed, and a second antenna element coupled to a second RF feed. The controllable circuit is configured to electrically connect the first antenna element to the first RF feed in a first antenna configuration and to electrically connect the first antenna element to ground in a second antenna configuration. During the second antenna configuration, the second antenna element is driven by the second RF feed.
