Example Embodiment

[0020] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, a person of ordinary skill in the art can understand that, in each embodiment of the present invention, many technical details are proposed for the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed in this application can be realized.

[0021] The first embodiment of the present invention relates to a metal frame antenna without breakpoints, such as figure 2 As shown, it includes: a metal frame 1, a metal ground plate 2, an antenna feed point 4, a first antenna branch 5, a second antenna branch 6 and an antenna matching module 7. Among them, the metal frame 1 is provided with a first g...

Abstract

The invention relates to the technical field of communication and discloses an unbroken metal frame antenna comprising a metal frame, a metal grounding plate, an antenna feed point, a first antenna branch, a second antenna branch, and an antenna matching module. The metal frame is provided with a first grounding terminal and a second grounding terminal which are both connected with the metal grounding plate so that a part of the metal frame and the metal grounding plate form a closed metal rectangular ring structure. The antenna feed point, the first antenna branch, and the second antenna branch are disposed on the metal frame and in the metal rectangular ring structure, wherein the antenna feed point is arranged between the first antenna branch and the second antenna branch. The antenna matching module is arranged in the metal rectangular ring structure for adjusting the high and low frequency bandwidth of the antenna. Thus, the appearance of a cell phone can meet the needs of a user, and can reduce the influence of holding the cell phone with a hand on the antenna performance, thereby improving the antenna performance under a holding state and improving call quality.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a non-breakpoint metal frame antenna. Background technique [0002] With the rapid development of communication technology, contemporary smartphones not only need to ensure functions such as calling, downloading, and navigation, but also continue to pursue the experience effect brought by the appearance of mobile phones to users. At present, most smart phones have introduced a metal frame, which can not only increase the firmness of the mobile phone, but also be more beautiful. However, the existence of the metal frame will affect the radiation of the internal antenna of the mobile phone, making the signal of the mobile phone poor, so that it will affect the normal use of the mobile phone by the user. [0003] In the process of realizing the present invention, the inventors found that the antenna design solutions with metal frames in the prior art are usually the following...
