Mobile phone antenna

The utility model provides a mobile phone antenna which comprises a carrier, a main antenna used for debugging the resonance point and the band width of the antenna, an auxiliary antenna used for improving the antenna performance, a feed point and a ground point, wherein the carrier comprises a first surface, a second surface and a side wall positioned between the first surface and the second surface; the main antenna is formed on the first surface of the carrier; the auxiliary antenna is formed on the second surface of the carrier; the main antenna and the auxiliary antenna are electrically connected through a connecting part, and the connecting part is formed on the side wall. By adopting the structure, the response frequency range can be increased under the condition of maintaining the small size of the antenna, so that the mobile phone antenna is favorable for the miniaturization of the mobile phone.
