Abstract
The present invention discloses a single-plate dual-band antenna for a wireless network device. The antenna comprises a base portion, a ground portion, a radiating portion and a signal portion. The base portion is combined with the wireless network device. The ground portion has an end connected with the base portion and extends upwards from the base portion to a certain height. The signal portion is generally perpendicular to the radiating portion, the ground portion and the base portion, respectively. The signal portion has an upper side and a lower end. The upper side is formed with a connecting edge connected with the radiating portion while the lower end is formed with a feed pin, so that the signal portion generally has a downwardly tapered, inverted triangular structure. The radiating portion further comprises a first radiating section and a second radiating section. The first radiating section extends a first length from an upper end of the ground portion along the connecting edge of the signal portion, while the second radiating section extends a second length sinuously from an end of the first radiating section distal from the ground portion.
