Broadband antenna and wireless communication device

Disclosed are a broadband antenna and a wireless communication device. The broadband antenna comprises a first radiating body, a second radiating body and a feed-in end; the first radiating body forms a part of a metal outer frame and is used to resonate a first signal component of a radio-frequency signal, the second radiating body is disposed an area surrounded by the metal outer frame and is used to resonate a second signal component of the radio-frequency signal, and the feed-in end is electrically connected between the second radiating body and a ground part and is used to feed the radio-frequency signal in; and the first radiating body and the second radiating body are spaced for a distance, and the distance enables the first radiating body and the second radiating body to generate a coupling effect so that first signal component of the radio-frequency signal is fed in the first radiating body via the second radiating body. The metal outer frame can be used to transmit and receive a wireless signal, so the antenna is cleverly integrated into appearance molding of the wireless communication device, a broadband effect is achieved then, and a product mechanism can be met then.
