ABSTRACT:
An antenna applied to a wireless network device comprises a base, a pair of embedded portions, and an antenna portion. The base has two sides opposite to each other. Each of the embedded portions has a side wall portion and a locking wing portion. The side wall portion is substantially vertical to the base and connected to the sides of the base, while the locking wing portion is connected to the side wall portion, substantially parallel to the base, and spaced apart from the base with a first height. The antenna portion is provided with a ground member, a radiation member, and a signal member. The ground member is substantially vertical to the base, connected to one of the two sides of the base, and spaced apart from the embedded portion with an interval. The radiation member is connected to the ground member, substantially parallel to the base, and spaced apart from the base with a second height. The signal member is connected to the radiation member, substantially vertical to the base, and formed with a free end separated from the base. When the antenna is positioned in at least one slot formed on a substrate of the wireless network device, the radiation member is spaced apart from the substrate with a height difference between the second height and the first height.
