Embodiment 1

[0026] This embodiment provides a full metal casing antenna system. Such as figure 1 Shown is a structural diagram of an all-metal housing antenna system according to the first embodiment of the present invention.

[0027] The full metal case antenna system includes: a radiating element for radiating or receiving radio frequency signals.

[0028] The radiation unit includes: a full metal casing 1 , a feeding point 2 and a grounding point 3 .

[0029] The radiation unit may serve as a part of the appearance of the mobile terminal, and it may be installed on the mobile terminal. Further, the all-metal casing 1 is an integrated structure of the back cover and the middle frame of the mobile terminal.

[0030] The full metal casing 1 includes: three sections of the metal casing. The three metal casings are in the same plane and connected by non-metallic materials. The three-section metal casing includes: a first-section metal casing 11 , a second-section metal casing 12 and a ...

Embodiment 2

[0039] Based on the full metal case antenna system in Embodiment 1, this embodiment provides a multi-working mode full metal case antenna system. Such as image 3 Shown is a structural diagram of a full metal casing antenna system according to a second embodiment of the present invention.

[0040] Facing the inner side of the full metal casing 1, between the first section metal casing 11 and the second section metal casing 12, along the length direction of the junction of the first section metal casing 11 and the second section metal casing 12, set a distance between the first section metal casing 11 and the second section metal casing 12 A distance between the first feed point 21 and the second feed point 22, and setting the first ground point 31 corresponding to the first feed point 21 and the second ground point 32 corresponding to the second feed point 22; Between the second section of the metal casing 12 and the third section of the metal casing 13, along the length dire...

Embodiment 3

[0053] Applying the full metal case antenna system to the mobile terminal forms a full metal case mobile terminal. The all-metal casing mobile terminal includes the all-metal casing 1 and the main board of the mobile terminal. The main board of the mobile terminal is located under the inner side of the full metal casing 1 . The all-metal-case mobile terminal applies the above-mentioned all-metal-case antenna system.

[0054] The signal unit for connecting with the feeding point 2 and the grounding unit for connecting with the grounding point 3 are arranged on the main board of the mobile terminal. Generally speaking, the main board of the mobile terminal is already provided with a signal unit and a grounding unit, so that the all-metal antenna system can share the signal unit and the grounding unit with the main board of the mobile terminal.

[0055] When the all-metal shell antenna system includes the first working mode, the second working mode and the third working mode as...

Abstract

The present invention provides a full metal jacket type mobile terminal and an antenna system thereof. The full metal jacket type antenna system comprises a full metal jacket, feed points and ground points. The full metal jacket is composed of three sections of a metal jacket, wherein the three sections of the metal jacket are in the same plane and are connected through the non-metallic material. On the inner side surface of the full metal jacket, the feed points and the ground points corresponding to the feed points are arranged at the connection parts of every two adjacent sections of the metal jacket. According to the technical scheme of the invention, the full metal jacket is designed as three sections, and every two adjacent sections of the metal jacket are connected through the non-metallic material. In this way, the formed full metal jacket has no adverse influence on the radio frequency signal radiation effect of the mobile terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a mobile terminal with a full metal shell and an antenna system thereof. Background technique [0002] In response to users' requirements on the aesthetic appearance of mobile terminals, people have begun to try to use metal casings in mobile terminals, thereby improving the aesthetic appearance of mobile terminals. However, the mobile terminal usually uses a built-in metal loop antenna, and the metal shell will shield or affect the radiation of the radio frequency signal of the antenna, reducing the communication performance of the mobile terminal. Contents of the invention [0003] The main purpose of the present invention is to provide a mobile terminal with a metal casing and its antenna system, so as to solve the problem in the prior art that the metal casing is easy to shield or affect radio frequency signal radiation. [0004] Based on the above technical problems, the present...
