Problems solved by technology

[0003] During the process of conceiving and implementing this application, the inventor found at least the following problems: due to the sharp increase in the number of antennas required by the mobile terminal and the occupation of the wiring space of the antennas, the distance between the antennas is relatively short, resulting in isolation between the antennas The accuracy cannot be guaranteed, and the radiation performance of the antenna is poor, which affects the consumer's experience of using the mobile terminal
In addition, the number of antennas in the existing mobile terminals is large, which greatly increases the design and manufacturing costs of the terminals.

Abstract

The invention relates to an antenna and a mobile terminal. The antenna comprises a feed end, a first radiator, a second radiator and a gap located between the first radiator and the second radiator. The feed end is electrically connected with the first radiator or the second radiator and provides a feed signal for the first radiator or the second radiator; the first radiator and / or the second radiator are / is part of a metal frame of the mobile terminal. According to the antenna, the space of the mobile terminal can be effectively saved, and the isolation between the antenna and other structures of the mobile terminal is improved.

Description

technical field [0001] The present application relates to the technical field of antennas, and in particular to an antenna and a mobile terminal having the antenna. Background technique [0002] With the rapid development of 5G technology, the number of antennas required for mobile terminals has increased significantly. At the same time, full screen is a new generation of innovative design. With the continuous popularization of full screen technology, major manufacturers continue to introduce the concept of full screen in order to increase the selling point of mobile terminals, which makes the design space of the antenna sharply reduced. [0003] During the process of conceiving and implementing this application, the inventor found at least the following problems: due to the sharp increase in the number of antennas required by the mobile terminal and the occupation of the wiring space of the antennas, the distance between the antennas is relatively short, resulting in isolat...
