Abstract
A communication device includes a system circuit board, a ground plane, a first antenna, a second antenna, a first metal element, and a second metal element. The ground plane is disposed on the system circuit board. The first metal element is substantially located between the first antenna and the second antenna. The first metal element is coupled to the ground plane such that a system ground plane is formed. The second metal element is adjacent to the first metal element and substantially located between the first antenna and the second antenna. The second metal element is coupled to the system ground plane. The first antenna, the second antenna, and the first metal element are substantially located at an edge of the system circuit board.
