A communication device including a ground element and an antenna element is provided. The antenna element is disposed adjacent to an edge of the ground element, and a loop structure is formed by the antenna element and the edge of the ground element. The antenna element includes a first and a second metal portions, and a first and second switches. When the first switch is turned on and the second switch is turned off, the first metal portion, the second metal portion, a shorting metal portion and the first switch form a loop antenna with the ground element. When the second switch is turned on and the first switch is turned off, an inverted-F antenna is formed by the second metal portion.

Communication device with reconfigurable low-profile antenna element

A communication device including a ground element and an antenna element is provided. The antenna element includes a metal element. The metal element is disposed at or adjacent to an edge of the ground element. The metal element is substantially perpendicular to the ground element. The metal element has a projection on the ground element, and the whole projection is in the internal of the ground element. The antenna element has a first feeding point and a second feeding point. The first and second feeding points are away from each other. The first and second feeding points are substantially positioned at two ends of the metal element, respectively. The first feeding point is coupled through a first switch and a first matching circuit to a communication module. The second feeding point is coupled through a second switch and a second matching circuit to the communication module.

Communication device and antenna element therein

A communication device includes a ground element and an antenna element. The antenna element includes a loop metal element and a branch metal element. The loop metal element is adjacent to an edge of the ground element. The loop metal element has a feeding end and a grounding end. The grounding end is coupled to the ground element. The feeding end is coupled through a capacitive element and a first inductive element to a signal source. A closed region is enclosed by the loop metal element and the edge of the ground element. The branch metal element is coupled through a second inductive element to a connection point on the loop metal element. The connection point is at the front-half portion of the loop metal element. The front-half portion includes the feeding end. The branch metal element substantially extends along an outer periphery of the loop metal element.
