Abstract: An antenna and a mobile terminal are disclosed that relate 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 printed circuit board (PCB) and the antenna, and the antenna is printed on the PCB. An embodiment of the present invention 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.
