Abstract: An antenna structure for mobile phone includes a branch antenna acting with a metal shell of the mobile phone, an insulating body located in the metal shell, a main antenna disposed on the insulating body to be coupled to the metal shell and having a feed portion, and a feed-line including a conductive portion welded with the feed portion. The metal shell has a back cover and a ring-shaped metal frame integrated with the back cover. A circuit board is located in the metal shell. The main antenna has a ground portion connected to a ground circuit of the circuit board, and the feed-line includes a braid portion connected with the ground circuit. The metal frame is formed into a continuous metallic loop configuration to ensure integrality and beauty of the metal shell for the mobile phone.
