Claim 10:
11. An antenna comprising:
an antenna ground;
a loop antenna resonating element configured to resonate in a first frequency band, wherein the loop antenna resonating element extends around a central opening;
an inverted-F antenna resonating element configured to resonate in a second frequency band, wherein a portion of the loop antenna resonating element forms a return path to the antenna ground for the inverted-F antenna resonating element;
an L-shaped antenna resonating element configured to resonate in a third frequency band, wherein the L-shaped antenna resonating element is disposed within the central opening of the loop antenna resonating element and has a proximal end connected to the antenna ground; and
an antenna feed configured to feed the loop antenna resonating element, the inverted-F antenna resonating element, and the L-shaped antenna resonating element.
