An antenna and a mobile terminal, relating to the technical field of antennae, and solving the problem of designing an antenna within a small space. The antenna comprises a first radiator (2) and a first capacitor structure (3). A first end (21) of the first radiator (2) is electrically connected to a signal feed end (11) of a printed circuit board (1) via the first capacitor structure (3). A second end (22) of the first radiator (2) is electrically connected to a ground end (12) of the printed circuit board (1). The first radiator (2), the first capacitor structure (3), the signal feed end (11) and the ground end (12) form a first antenna, used to generate a first resonant frequency. The electrical length of the first radiator (2) is less than or equal to an eighth of a wavelength corresponding to the first resonant frequency. |
