An antenna for a terminal includes: a metal frame surrounding four sides of the terminal, a circuit board positioned within the metal frame and at least two radiation units arranged on the circuit board. The metal frame includes a bottom frame and a side frame defined by two breaking joints disposed on a side of the metal frame. A signal feed point is arranged on the circuit board, the signal feed point is connected with the bottom frame through a first radiation unit. At least two first grounding points are also arranged on the circuit board, the at least two first grounding points are positioned on one side of the signal feed point, the at least two first grounding points are connected with the bottom frame through a second radiation unit, and the bottom frame is configured to generate low-frequency resonance.
