Metal frame terminal antenna and terminal

The present invention discloses a metal frame terminal antenna and a terminal. The disclosed metal frame terminal antenna is used for a metal frame terminal, a metal frame comprises a lower frame, a first side frame and a second side frame, and the break-joint width between the lower frame and the first side frame and the break-joint width between the lower frame and the second side frame are both increased to a preset width. The antenna comprises a feeding point, a first grounding point and a switching switch, wherein the feeding point and the lower frame are connected via a first branch, and the first branch is connected with the lower frame. The first grounding point and the switching switch are connected via a second branch, the second branch is connected with the lower frame, and the switching switch is used to realize the switching between at least two communication modes. According to the present invention, by increasing the break-joint width between the lower frame of the metal frame and the first sid
