COMMUNICATION DEVICE AND ANTENNA ELEMENT THEREIN

摘要

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.
