Provided are a combined antenna system and a mobile terminal. The combined antenna system comprises: a metal shell arranged at the rear part of a mobile terminal and a multi-interval tunable antenna, wherein the metal shell comprises a first side shell, a middle shell and a first gap arranged between the first side shell and the middle shell, and the multi-interval tunable antenna covers a low frequency band, a middle frequency band and a high frequency band at the same time, and comprises a first metal wire and a second metal wire, with the first metal wire being electrically connected to the first side shell and a radio frequency power supply inside the mobile terminal respectively, the second metal wire and the first metal wire being arranged at an interval, and the second metal wire being electrically connected to the first side shell. The combined antenna system provided by the present invention matches an all-metal shell, and can realize coupling tuning by adjusting the size of a coupling interval on a first metal wire and a second metal wire, thereby relatively improving the radiation efficiency of a product, and enabling the product to meet performance requirements of various network standards of a mobile terminal in the future. |
