Abstract
A dual wideband dipole antenna used for wireless communication and receiving electromagnetic signals is revealed. The antenna mainly includes a dielectric substrate, two radiating metal portions and a feed line. Each radiating metal portion consists of a metal plate, an L-shaped metal piece and a rectangular metal sheet. An initial end of the metal plate has a feeding point. The metal plate has a regulatory segment and a projecting segment. The L-shaped metal piece is between a terminal end of the metal plate and the regulatory segment. The L-shaped metal piece has a turning portion. The rectangular metal sheet is between the terminal end of the metal plate and a rear end of the regulatory segment of the other metal plate. The feed line connects the feeding points. Thus the antenna is excited to produce resonance frequencies at 0.85, 1.13, 1.68, 1.93 and 2.29 GHz and cover GSM850/900/1800/1900 bands.
