Abstract: A communication device includes a ground metal element and an antenna element. The antenna element includes a first metal element, a second metal element, a third metal element, a first capacitive element, a second capacitive element, an inductive element, and a signal feeding source. A first connection point of the first metal element is coupled through the first capacitive element to the third metal element. A second connection point of the first metal element is coupled through the second capacitive element to the ground metal element. A third connection point of the second metal element is coupled through the inductive element to the third metal element. A shorting end of the third metal element is coupled to the ground metal element. The signal feeding source is coupled between the first metal element and the third metal element or the ground metal element.
