Abstract: An antenna of a mobile terminal is provided. At least two slots are disposed in a metal bezel of the mobile terminal, and the two slots divide the metal bezel into a first metal section, a second metal section, and a third metal section. A radiating element of the antenna includes the second metal section located between the two slots, a first conductor, and a second conductor. The first conductor and the second conductor are separately connected to the second metal section. A feed point is connected to the first conductor by using a matching network. A ground point is connected to the second conductor to form a loop antenna. An electrical length path of current from the feed point to the second metal section is not equal to an electrical length path of current from the ground point to the second metal section.
