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.

Abstract: A microstrip antenna includes a radiator and a first feed and a second feed that are configured to feed a radio frequency signal, and a first feedpoint and two second feedpoints are disposed on the radiator. The first feedpoint is located at a central position of the radiator, and the first feedpoint is electrically connected to the first feed, and is configured to feed a radio frequency signal into the radiator, to excite the radiator to generate a TM02 mode. The two second feedpoints deviate from the central position of the radiator and are spaced apart from the first feedpoint. The second feed is electrically connected to the second feedpoints through an adjustment circuit. The second feedpoints are configured to feed a radio frequency signal into the radiator, and the second feedpoints excite, by using the adjustment circuit, the radiator to generate a TM10 mode.
