Abstract
Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes an antenna element that is self-resonant at a first frequency in a first mode and self-resonant at a second frequency in a second mode. A radio frequency (RF) is coupled between the antenna element and a ground plane. A RF circuit, coupled to the antenna element via an RF feed, is operable to control the RF switch to switch the antenna element between the first mode and the second mode. The RF circuit is operable to cause the antenna element to radiate or receive electromagnetic energy in a first radiation pattern in the first mode and to radiate or electromagnetic energy in a second radiation pattern in the second mode.
