Terminal

A terminal, wherein a metal back cover of the terminal includes a slot that divides the metal back cover into two parts, and one of the two parts is used as an antenna radiator of the terminal;

• wherein the antenna radiator includes a signal feed point, a first ground point, and at least one second ground point, so that an antenna of the terminal has four resonance points, wherein
• the signal feed point is connected to a matching network, the first ground point is grounded by a switch device, and the second ground point is grounded;
• and a distance between the signal feed point and the first ground point is less than a distance between the signal feed point and the second ground point, and none of the signal feed point, the first ground point, and the second ground point is located in a position, corresponding to an end of the slot, on the antenna radiator.
