Abstract
Antenna structures and methods of operating the same are described. One apparatus includes a metal cover having a first corner ground element, a second corner ground element, a first strip element, a second strip element, a radio frequency (RF) feed, and a RF circuit. The first strip element is physically separated from the first corner ground element by a first cutout in the metal cover. The first strip element is physically separated from the second strip element by a second cutout in the metal cover. The second strip element is physically separated from the second corner ground element by a third cutout in the metal cover. The RF circuitry is coupled to the RF feed, where the RF circuitry is operable to cause the first corner ground element and the first strip element as well as the second corner ground element and the second strip element to radiate electromagnetic energy.
