Abstract
A dipole antenna is disclosed. The dipole antenna includes a feed-in terminal, a balun, a first radiator and a second radiator. The feed-in terminal is used for feeding in a radio-frequency signal. The balun is electrically connected to the feed-in terminal for driving out a return current of the dipole antenna to balance a feed-in impedance of the dipole antenna. The first radiator is electrically connected to the feed-in terminal and the balun for radiating the radio-frequency signal in a first frequency band. The second radiator is electrically connected to the first radiator, the feed-in terminal and the balun for radiating the radio-frequency signal in a second frequency band.
