COMMUNICATION DEVICE

摘要

A communication device includes a housing, a system circuit board, and an antenna element. A metal plane of the housing is disposed on a back surface of the housing. An edge of the metal plane is aligned with an edge of the back surface. The antenna element includes a metal piece and a printed circuit board. The metal piece is disposed on a side surface of the housing. The metal piece extends along the edge of the metal plane. The metal piece is also separated from the edge of the metal plane by a nonconductive region. The printed circuit board includes a circuit. The printed circuit board has a first connection point and a second connection point. The first connection point is coupled to a signal source. The second connection point is coupled to the metal piece, and is used as a feeding point of the antenna element.
