Abstract

The present invention discloses a monopole antenna adapted for a wireless network device. The antenna includes a base portion, a ground portion, a radiating portion and a signal portion. The ground portion extends a predetermined height upwardly from the base portion. The radiating portion is connected to an end of the ground portion away from the base portion and is substantially perpendicular to the ground portion. The signal portion is connected to the radiating portion and is substantially and respectively perpendicular to the signal portion and the ground portion. The signal portion has a feed terminal formed on an end thereof away from the radiating portion. A connecting side, where the ground portion and the base portion are connected, has a width that is smaller than a width of another connecting side, where the ground portion and the radiating portion are connected; and a connecting side, where the signal portion and the radiating portion are connected, has a width that is larger than a width of the end of signal portion away from the radiating portion. The antenna is a single component integrally formed by stamping an electrically conductive thin metal plate, which facilitates not only fabrication thereof, but also the assembly of the antenna to a substrate of the wireless network device and increases the gain and bandwidth of the wireless network device along a vertical direction as well.
