Abstract: An electronic device includes a metal frame, a feed unit, a switch, a matching network, and a first radiator. The first radiator is part of the metal frame and disposed along two adjacent edges of the electronic device, where a feed point of the first radiator is disposed in a junction area of two adjacent edges of the metal frame, and the feed unit feeds the first radiator at the feed point. The first radiator is configured with a first ground point located between the feed point and a first end of the first radiator, and the first radiator is grounded at the first ground point. The first radiator is configured with a second ground point located between the feed point and a second end of the first radiator. The switch is electrically coupled between the second ground point and the matching network.

Abstract: An antenna disposed on a mobile terminal, where the mobile terminal includes a radiation portion and a circuit board, the circuit board includes a lateral side and a grounding layer, and an insulating slot divides the radiation portion into a feed stub and a parasitic stub. A gap is encompassed by the circuit board and the radiation portion. There is a first branch that extends from the feed stub to the gap for feeding the antenna, and there is a second branch that extends from the parasitic stub to the gap and that is electrically connected to a grounding portion. The antenna excites a current loop winding around the gap on the grounding portion, the feed stub, and the parasitic stub.
