Claim:
1. A wideband antenna, comprising: a first radiator formed as a part of a metal frame for resonating a first signal component of a radio-frequency signal; a second radiator disposed within an area enclosed by the metal frame for resonating a second signal component of the radio-frequency signal, comprising: a first parasitic radiator comprising: a second parasitic radiator electrically connected to the ground, extending from the ground along the first direction, and disposed between the first arm and the first radiator; and the feed terminal electrically connected to the second radiator for feeding the radio-frequency signal; wherein there is a distance between the first and second radiators such that a coupling effect is induced between the first and second radiators, which allows the first signal component being fed from the second radiator into the first radiator via the coupling effect.
