Abstract
A communication device including a ground element and an antenna element is provided. An edge of the ground element has a notch, and the antenna element includes a metal element disposed inside the notch. The metal element of the antenna element has a first end and a second end. The first and second ends are spaced away from each other and are respectively positioned adjacent to two ends of a diagonal line of the notch. The first end is used as a first feeding point of the antenna element, and the second end is used as a second feeding point of the antenna element. The first feeding point is coupled through a switch and a first matching circuit to a first signal source, and the second feeding point is coupled through an inductive element and a second matching circuit to a second signal source.
