An antenna and a mobile terminal are provided. The antenna may include a radiation unit and at least one parasitic unit. The radiation unit includes a first radiation sub-unit and a second radiation sub-unit. A first terminal of the first radiation sub-unit is connected to a bottom edge of a rear cover of the mobile terminal. A second terminal of the first radiation sub-unit is provided with a feed point, a first terminal of the second radiation sub-unit is connected to the bottom edge. A second terminal of the second radiation sub-unit is provided with a ground point. A distance from the feed point to the ground point is greater than zero and less than a preset value. The at least one parasitic unit is coupleable with the radiation unit via the feed point.
