Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] In order to solve the above-mentioned technical problems of relatively weak radiation performance and limited bandwidth of mobile phone antennas in the traditional technology, in one embodiment, a terminal back cover is proposed. The terminal back cover is suitable for terminals with an all-metal shell design, that is, the back cover and side wrapping of the terminal are made of metal. In this embodiment, the terminal back cover may be a mobile phone back co...

Abstract

The embodiment of the invention discloses a terminal back cover. The terminal back cover comprises a main ground part and a radiation part made of metal material, a gap parallel to a short side of the rectangular mobile back cover and filled by an insulation material is arranged between the main ground part and the radiation part, and the main ground part is connected with a ground wire on a terminal main board; the radiation part is used as a radiating body of an antenna of the terminal, the inner surface of the radiation part is provided with a first feed point to connect with a feed wire on the terminal main board; the edge of the radiation part of the terminal back cover is further provided with a first metal route extending to the internal of the terminal and parallel to the inner surface of the radiation part. An antenna system at the terminal back cover provided by the invention is lower in antenna clearance rate requirement and higher in radiation performance.

Description

technical field [0001] The invention relates to the technical field of mobile phone antennas, in particular to a terminal back cover. Background technique [0002] In the traditional technology, as users' requirements on the appearance and experience of mobile terminals continue to improve, more and more metal casings are used in mobile phones. However, if the mobile phone antenna is designed according to the method of the built-in antenna in the traditional technology, the mobile phone antenna will be easily shielded by the metal case due to the closeness of the metal case. Mobile phone antennas are often middle-frame antennas, loop or slot antennas, usually in the form of a metal middle frame + plastic back cover, and plastic is filled to the breakpoint or gap, but the above-mentioned metal middle frame + plastic back cover mobile phone Neither support full metal back cover. [0003] In the traditional technology, in order to use an all-metal back cover and maximize the ...
