description The invention relates to a multi-band antenna used in a GSM frequency band, which comprises a base, a high-frequency radiation part and a low-frequency radiation part. The base comprises a first end and a second end opposite to the first end; wherein, the first end is provided with a grounding point; and the second end is provided with a signal feed point. The high-frequency radiation part extends outwards from one side of the second end, so as to work at the high-frequency band. The low-frequency radiation part extends outwards from the other side of the second end, so as to work at the low-frequency band. Moreover, the low-frequency radiation part comprises a first radiation segment which is connected with the second end and a second radiation segment which extends from one end of the first radiation segment to be far away from the first end; wherein, the first radiation segment is provided with at least one slot opening which is used for controlling the fall point of the low-frequency range.
