Abstract
An antenna structure includes a metal shell including a grounded middle frame provided with a main body and sides bent and extending from two sides of the main body and a radiating part serving as an antenna radiating body. The radiating part forms an insulation filled gap with the middle frame. Two ends of the radiating part are arranged opposed to each other for forming an insulation filled breaking joint. A circuit board is arranged below the metal shell, and one side of the circuit board adjacent to the radiating part forms a clearance zone between the circuit board and the radiating part. The antenna further includes a feeding point, at least one ground point, and a tuning circuit. The feeding point is close to the breaking joint, and the ground point includes a first ground point and a second ground point.
