The present utility model discloses an antenna and a mobile terminal, and relates to the communications field. The antenna includes a ground cable and a feeder, where the feeder includes a low-frequency branch and a high-frequency branch; the low-frequency branch and the high-frequency branch have a common endpoint; the low-frequency branch is surrounded by the ground cable to form a coupled loading mode and an equivalent coupled feed loop antenna radiation mode; and the high-frequency branch is set outside the ground cable to complete a high-frequency monopole radiation mode. The mobile terminal includes a PCB board and the antenna, and the antenna is printed on the PCB board. An embodiment of the present utility model resolves a problem of insufficient low-frequency bandwidth and insufficient high-frequency bandwidth in the prior art, effectively improves performance of the antenna, and can effectively disperse near-field energy to the PCB and the mobile terminal, thereby achieving an objective of reducing an SAR, saving cost, and increasing an effective distance from the antenna to an SAR test instrument trunk model. |
