Abstract
A communication device includes a ground plane and an antenna element. The antenna element includes a radiation metal strip and a feed metal line. The feed metal line is disposed between the radiation metal strip and the ground plane. A first metal strip of the radiation metal strip has a first end electrically connected to the ground plane by a first metal section. A second metal strip of the radiation metal strip has a second end electrically connected to the ground plane by a second metal section. The first metal strip is coupled to a first connection point on the feed metal line through a first capacitive element. The second metal strip is coupled to a second connection point on the feed metal line through a second capacitive element. The feed metal line has a third connection point as a feeding point of the antenna element.
