Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes a radio coupled to a RF feed and an RF switch, a first antenna element coupled to the RF feed, and a second antenna element coupled to the RF switch, the RF switch being coupled to a grounding point of a ground plane. The radio controls the RF switch between a first mode and a second mode. The radio causes the first antenna element to radiate electromagnetic energy in a first radiation pattern in the first mode and causes the second antenna element to radiate electromagnetic energy in a second radiation pattern in the second mode. The second radiation pattern is different than the first radiation pattern.
