description The utility model discloses a multi-frequency antenna made of metal material, which is provided with an antenna main body and a fed in part. The antenna main body includes a first long strip part, a second long strip part perpendicular to one end of the first long strip part and a convex part approximately arranged on the other end of the first long strip part. The fed in part is connected with the convex part, the fed in part comprises a plurality of continuous bending parts, one end of the fed in part is connected with the convex part to form a fed in point, the other end of the fed in part forms a signal transmit and receive part, a grounding part is adjacent to the signal transmit and receive part, a matching circuit is connected between the signal transmit and receive part and the grounding part. So through the shape and connection position design of the antenna main body and the fed in part, the multi-frequency antenna is suitable for transceiving the more low frequency GSM850 and EGSM frequency band and the more high frequency DCS1800 and PCS1900, W-CDMA2100 and Wi-Fi frequency band.
