ANTENNA OF MOBILE TERMINAL AND MOBILE TERMINAL

WIPO Patent Application WO/2018/171057

A1

An antenna of a mobile terminal and the mobile terminal. At least two gaps are provided on a metal frame of the mobile terminal. The two gaps divide the metal frame into a first metal section, a second metal section, and a third metal section. A radiating unit of the antenna comprises the second metal section arranged between the two gaps, a first conductor, and a second conductor, the first conductor and the second conductor respectively being connected to the second metal section. A feedpoint is connected to the first conductor via a matching network; a ground point is connected to the second conductor, thus forming an annular antenna. Moreover, an electrical length path of a current from the feedpoint to the second metal section is not equal to an electrical length path of the current from the ground point to the second metal section. In the described technical solution, the feedpoint and the ground point are provided at a side of the center line of the metal sections, and the radiating unit employs an annular structure to form the annular antenna, thus changing the maximum point of an electric field to be away from the gaps of the metal frame, reducing impact that a hand has on a modal electric field, and increasing the performance of the antenna.
