Problems solved by technology

However, the internal space of the mobile phone is limited and due to the structure and position of the metal frame, it cannot be flexibly designed according to the needs of the antenna. Therefore, how to use the metal frame with a given shape and position to achieve the coverage of multiple working frequency bands of the antenna has become a realistic demand.

Abstract

The invention relates to a multi-band antenna and a mobile terminal. The multi-band antenna is used for the mobile terminal with a metal frame and comprises a frame segment of the metal frame, a feeding point, a grounding point, a first branch, a second branch and a third branch, wherein the feeding point is connected with the frame segment via the first branch, the grounding point is connected with the frame segment via the second branch, the first branch, the second branch and the third branch are all connected with the frame segment, and the third branch is arranged between the first branchand the second branch. In the multi-band antenna, the coverage of various working frequency bands, particularly a 2.4GHz WiFi frequency band, a 5GHz WiFi frequency band and a GPS frequency band, canbe conveniently achieved by employing a part of the mobile terminal as the metal frame, the antenna is simple in structure and small in occupancy space and is convenient to debug, and miniaturizationand multiple frequencies of the antenna are achieved.

Description

technical field [0001] The present disclosure relates to a multi-band antenna and a mobile terminal. Background technique [0002] With the continuous development of communication technology, the demand for multi-band antennas is getting higher and higher. In order to cover multiple working frequency bands, in related technologies, multiple antennas need to be installed inside the mobile phone or the metal frame of the mobile phone is used as the antenna. However, the internal space of the mobile phone is limited and due to the structure and position of the metal frame, it cannot be flexibly designed according to the needs of the antenna. Therefore, how to use the metal frame with a given shape and position to achieve the coverage of multiple working frequency bands of the antenna has become a realistic demand. . Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure provides a multi-band antenna and ...
