Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, various implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.

[0024] A first embodiment of the invention relates to an antenna system. Such as figure 1 As shown, the mobile phone antenna with a metal frame includes a metal casing 101, a circuit board 104 disposed in the metal casing 101 and having a grounding point, a bracket 105 disposed in the metal casing 101 and p...

Abstract

The embodiment of the present invention relates to the field of communication technology, and discloses a mobile phone antenna with a metal frame, including: a metal case, a circuit board disposed in the metal case, a bracket disposed in the metal case, and a circuit board and the support. For the antenna part, the metal casing includes a metal middle frame and a metal frame. A gap is opened between the metal frame and the metal middle frame, and the antenna part includes a feeding point, a tuning switch circuit and a third antenna. By using a part of the circular metal frame of the metal middle frame as an antenna radiator, the metal middle frame and the metal frame of the mobile phone are seamless. The weakening of the strength of the metal frame of the mobile phone due to cutting is avoided, and the cost increase caused by the cutting and injection molding process in the prior art is saved. And the third antenna is added, and the metal frame and the third antenna are combined to form the overall antenna part, which avoids the problems of poor isolation and poor signal transmission performance of the mobile phone antenna caused by the independent design of the antenna.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a mobile phone antenna with a metal frame. Background technique [0002] With the advancement of science and technology and the development of electronics and communications, mobile terminals such as mobile phones and tablet computers are becoming more and more popular, and more and more terminals use full metal shells or metal frames to improve the appearance and texture of products. However, the appearance or texture of this product and the antenna performance of the terminal often restrict each other, coupled with the development trend of thinner and lighter terminals, the design space of the antenna is getting smaller and smaller. In order for the RF signal generated by the antenna to penetrate metal, special designs must be used in most cases. A commonly used design is to create a break on the metal casing or metal frame, so that part of...
