Abstract
The present invention discloses an antenna adapted for use in a wireless network device. The antenna includes a base and two antenna portions. Each antenna portion includes a ground section, a radiation portion and a signal section. The ground sections of the two antenna portions are connected with the same base. The radiation portion is connected with the ground section. The radiation portion has a first radiation section and a second radiation section wherein an external arm of the first radiation section is extending beyond and along the outer edge of the second radiation section and is separate from the second radiation section at a distance. The signal section is connected with the radiation portion in the manner that the first radiation section and the second radiation section are respectively positioned at two opposite side and a free end of the signal section is separate from the base. The antenna is a single component integrally formed by stamping an electrically conductive thin metal plate, which not only facilitates fabrication thereof, but also the assembly of the antenna to a substrate of the wireless network device, thereby increasing the gain of the wireless network device along a vertical direction.
